清水混凝土表观性状控制要素解析

Analysis on the control factors of surface properties of architectural concrete

清水混凝土以最纯粹的建筑语汇成为建筑美学表现的重要手法和材料。随着环保意识和建筑整体水平的不断提高,清水混凝土已在我国工业及公共建设领域广泛应用。但因施工难度大,可变因素多,尤其是决定清水混凝土建筑外观的色彩、质感、肌理等表面性状调控仍是一道难题,现状还是通过试浇注标准块、依赖现场施工经验,相关的定量化研究少而又少,很难把握清水混凝土表面性状调控的基本原理,更无法进行系统的整体设计。本文针对清水混凝土建筑的表观性状,通过查阅三十年来日本清水混凝土的相关研究文献,分析归纳文献中的实验数据和结果,旨在总结影响清水混凝土表观性状的主要因素,并作为清水混凝土表观研究的基础资料。

As the most typical building material in 20 th century, concrete is widely applied to construction fields. Architects＇ are fond of it because of its unique color, texture and shape. In China, with the objective demands of green buildings, the demand of architectural concrete is not only be used in infrastructure projects, but also in fields of industry and civil construction. But, from the point of the overall aesthetics of architectures, the architectural concrete＇s surface properties, especially color adjustment is a very important factor which is still not being solved. Nowadays, color adjustment is still determined by the construction qualitative experiences, and relevant quantitative research result is very few. Consequently, the basic method of architectural concrete＇s color adjustment cannot be grasped as a whole and even be designed totally and systematically. This paper has sort out relevant research literature of Japan architectural concrete in 30 years, analyzed and summarized in the literature data and the results of the experiments, aims to summarize the main factors affecting the water concrete apparent properties, and as basic data of architectural concrete research.
