Use of CCW （Civil Construction Waste） in Soil Improvement

The vast production of CCW （Civil Construction Waste） has caused socio-environmental concern as a result of the exploration of natural resources, clandestine disposal and proliferation of vector-borne diseases, for example. It now gives priority to non-generation, reduction and recycling of CCW. This study, therefore, seeks an alternative for CCW by comparing the physical and mechanical characteristics, both in laboratory and onsite, of the recycled CCW aggregate and natural aggregate （stone powder）, commonly used in the composition of compaction piles for improving soils in foundation works in the city of Recife, Pernambuco, Brazil. All results showed similar behaviours among the investigated samples （CCW recycled and natural）, confirming the satisfactory performance of the investigated CCW material.

Research Characterized the Physical Properties of Recycled Aggregate of Civil Construction Wastes

One of the big problems of the urban centres of the cities in Brazil is the growth of the generation of the Civil Construction Waste （CCW）. A disturbing concern for the public and private sectors is to find proper disposal of Urban Solid Waste （USW） in large cities, since suitable dumping sites for this waste are increasingly scarce due to the spread and development of large urban centres. In general, recycling is currently one of the procedures most studied by researchers for disposal of such waste. In this context and aiming a new application for recycled CCW aggregates, the research characterized the physical properties of the material to use in fill compaction piles in soil improvement. The analysis shows results from laboratorial tests executed in CCW recycled samples, which came from works in different construction stages from Recife-PE, and natural aggregate, adopted as a reference. Characterization tests were performed with samples CCW recycled CLue aggregates and samples of natural fine aggregate （stone powder）. The results of characterization tests showed similarities between the CCW samples tested and the reference samples, indicating that the civil construction wastes has potcntial use as material for consolidation piles in foundation works.

How does the construction of China’s ecological civilization affect the health burden of urban and rural residents?

Accelerating the construction of ecological civilization and promoting the management of health environment problems is one of the core elements of the implementation of the“Beautiful China”and“Healthy China”strategies with Chinese characteristics in the new era.Based on the scientific connotation of ecological civilization,this paper systematically assesses the level of interprovincial ecological civilization construction in China using the combined CRITIC empowerment method and explores the impact of ecological civilization construction on the health burden of urban and rural residents using interprovincial panel data from 2003 to 2018 with the help of panel feasible generalized least squares,simultaneous equation estimation,and the extended regression model.It is found that there is a significant inverted U-shaped relationship between provincial ecological civilization construction and urban and rural residents’economic health burden,as well as a significant U-shaped relationship between ecological civilization construction and urban and rural residents’disease burden.Fiscal decentralization,urbanization,and industrialization are the three important indirect mechanisms through which ecological civilization affects the health burden of urban and rural residents,and fiscal decentralization plays a typical role in crowding out the health effect of ecological civilization.In the eastern and central regions,ecological civilization construction has effectively reduced the health burden of urban and rural residents,but it is more significant for improving the economic health burden of rural residents.While the“catching-up trend”of the progress of ecological civilization construction in the western region is obvious,ecological civilization plays an important role in alleviating the economic health burden of urban residents.After the robustness test,the conclusion still holds.This study provides an important empirical basis for local governments to improve the accuracy of their policies in promoting the“Beautiful China”and“Healthy China”strategies.

An analysis on ecological civilization construction in Gansu based on a quantified SWOT framework

Ecological civilization （EC） construction has become one of the key elements of China＇s reform and development process, since it was put forward at the 17th National People＇s Congress （NPC） in 2007 and improved at the 18th NPC in 2012, and stressed at the third plenary session of the 18th NPC. The provincial areas are the most important pilot units of EC strategy. Therefore, research on EC at the provincial level can meet the practical demand for EC in China. Based on the existing provincial circumstances in Gansu and its significant position as an ecological barrier in northwestern China, and aiming at the core issue of why and how to build EC in Gansu, this paper employs SWOT （strengths, weaknesses, opportunities, threats） analysis, the Delphi method, and a combined quantitative analysis and coordinate method, and then calculates the relevant strategic orientation angle （0 = 1.4605） and strength coefficient （p = 0.53）. The results show that Gansu should take an opportunities-dominated strategy, and choose opportunity-strength measures, so the province can increase its in- ternal strengths and decrease its weaknesses with external promote an EC construction strategy. opportunities. Specific measures are recommended to actively

A Methodology for Collection of Residential Construction Residue in Manaus

Civil construction is one of the largest consumers of raw materials and producers of waste, which has been causing environmental problems both through the extraction of raw materials and through building activity by generation of waste. Notwithstanding the need to find an optimum use for solid construction residue to try to solve or minimize this problem, there are no standards for the process of obtaining the CDR （construction and demolition residue）. Thus, the aim of this study was to develop a method of collecting solid waste at the construction site that is easy and low-cost and thus can be applied throughout the construction industry. This collection method was designed to produce residue with the desired proprieties and obtain the best possible homogeneity. This method permitted to evaluate the factors generating construction residue more precisely.

Obstacles to the Success of Organizational and Managerial Innovation in Construction SMEs in Burkina Faso

This research is based on a qualitative approach based on the exploitation of secondary data.The objective of the research is to determine the factors likely to influence the success of innovation in small and medium enterprises(SMEs)of Building and Public Works(BTP)in Burkina Faso.To do this,we issued two research proposals that served as a guide for our research.It emerged that 77% of SMEs reported having innovated in 2019,while the same study concluded to the underperformance of these companies.Hence,there is the need to distinguish between innovation actions and the success of innovation.For us,the success of innovation is based on information transparency in the company and the development of human resources.The results showed that the information does not circulate the construction companies and it results in a lack of meeting place.In addition,construction and civil engineering SMEs lack competent and qualified staff and are not very motivated.Indeed,only 52% of business leaders are satisfied with the motivation of their staff.In terms of competence,97% business leaders say that they have qualified staff and even 87% say not to delegate because they lack qualified staff.In fact,obtaining approval requires the existence of qualified personnel in the company,which justifies this assertion to 97%.And yet,the staff presented for the approval is not the one available in the company.Moreover,the lack of competent and motivated staff is confirmed by the MOE and MOD.Our two research proposals have been validated.However,we noted that this is a partial search for the factors that influence the success of innovation in construction SMEs that could be complemented by other research.

Identification of the Origins and Risks of Pathologies in Steel Structure Buildings Using Total Quality Management Tools

The steel structure construction is an interesting option to the already established concrete structure at a time when the Brazilian civil construction seeks more efficiency.To promote the use of this material it is necessary to have a better understanding of its characteristics and,especially,of its possible pathologies,to avoid degradation,costs,and even the collapse of the structure.In this study Total Quality Management tools were applied to analyze the pathologies found in five medium and large steel-structured buildings.The most frequent ones were structure corrosion,cracks in the closures,and infiltrations in the interface closure/structure.The Ishikawa Diagram is used to identify the origin of the causes of pathologies and the Gravity Urgency Tendency Matrix(GUT Matrix)is used in the risk analysis of each pathology.The results obtained show that it is possible,through these Quality Management tools,to understand the origin of the pathologies,establishing their dangerousness and the degree of risk each one offers.

BIM Implementation--A Bibliographic Study of the Benefits and Costs Involved

The construction sector has always been constantly changing, becoming increasingly aggressive, requiring new strategies to adapt to international and national scenarios. In the development of a project, there are many constraints, which often end up in problems such as waste materials, generating waste affecting the environment and also resulting in high costs oftbe work that could be avoided. Then came the concept of BIM （building information modeling） defined by a digital model consists of a database, allowing the development of projects with various professionals working in an integrated manner, being able to support all aspects of the life cycle of the project. Therefore, from the research information on the implementation of BIM methodology, it was possible to propose new ways of thinking and designing buildings, contributing to the completion of research in the management of projects and sustainability areas relevant to the development of engineering.

Review of Tourism Ecological Security from the Perspective of Ecological Civilization Construction

In the era of sustainable development,the ecological impact of the development of the tourism industry has attracted extensive attention from all walks of life.Generally considered,tourism ecological security(TES)is an important link to realize the high-quality development of tourism destinations and promote the construction of ecological civilization.Based on keyword discrimination of TES,tourism ecological risk and tourism ecological health,and from the perspective of ecological civilization construction,this paper uses the databases of Web of Science and CNKI as data sources to systematically comb and analyze TES research from the aspects of development process,research methods and research content,and puts forward the prospects for future research on this basis.This analysis found that research in the TES field presents four main characteristics.(1)The phased characteristic of“germination-exploration-development”is significant,and a relatively standard research framework of“evaluation-influencing factors-early warning-regulation”has been formed.(2)The empirical orientation of the research methods is distinct.(3)The development trend is characterized by small-scale dominance and a large-scale surge.(4)The disciplinary integration and practical combination have been continuously strengthened.Combined with the development trends and hot spots of TES,this paper proposes that the direction and goal of deepening TES research in the future should be carried out from the aspects of strengthening research on thresholds,early warning and regulation,improving the application of big data,constructing the synergistic effect mechanisms between tourism and ecology,and realizing the longitudinal deepening and interconnection of scale research.

Research on the Realization Mechanism of and Approach to Ecological Product Valuations

Ecological product is an innovative practice for ecological valuations in China. Due to the influence of historical conditions and development stages in China, research on the realization of ecological valuations has lagged. In the new era, the construction of an ecological civilization guided by the "Two Mountains" theory has been promoted to the national strategic level and is supporting the growth of theoretical research and practical exploration based on the understanding of ecological product values. We want to innovate and improve the system used to realize the value of ecological products by applying the existing research, which focuses on the concept definition of ecological products and their correlation theories. Through systematic expansion and upgrades in this system, the evaluation accuracy of ecological products can be improved, providing valuable references for further practical exploration and promoting an ecological culture in China.
