钢纤维轻骨料混凝土力学性能影响因素研究综述

A Review on the Influence Factors of Mechanical Properties of Steel Fiber Lightweight Aggregate Concrete

钢纤维轻骨料混凝土作为一种质量轻、强度高、韧性好的新型复合材料,在土木工程领域应用广泛。现如今,各行各业发展都必须坚持绿色、环保、无污染的原则,建筑材料也应该满足国家对建筑行业发展要求。钢纤维轻骨料混凝土中的轻骨料是一种节能环保材料,能变废为宝,实现绿色可持续发展,因此对于钢纤维轻骨料混凝土的研究和应用越来越多。本文主要对水胶比、轻骨料种类、粉煤灰替代率和钢纤维掺量等因素对钢纤维轻骨料混凝土力学性能的影响进行综述,进一步系统地说明钢纤维轻骨料混凝土力学性能的变化规律。

Steel fiber lightweight aggregate concrete,as a new type of composite material with light weight,high strength and good toughness,is very popular in civil engineering field.Nowadays,the development of all walks of life must adhere to the principles of green,environmental protection and pollution-free,and building materials should also meet the national requirements for the development of the construction industry.Light aggregate in SFRLAC is a kind of energy saving and environmental protection material,which can turn waste into treasure and realize green and sustainable development.Therefore,research and application of SFRLAC are increasing.In this paper,the influences of factors such as water-binder ratio,lightweight aggregate type,fly ash replacement rate and steel fiber content on SFRLAC mechanical properties were summarized,and the variation rules of SFRLAC mechanical properties were further explained systematically.
