摘要
以往对混凝土的研究,土木工作者把更多的注意力放在了水泥、水灰比、外加剂以及粉煤灰和硅灰等外掺材料上。集料也是混凝土的重要组成部分,在混凝土中占有很重要的地位。随着土木建设的日趋发展和完善,天然砂日益紧缺,我们应重新审视集料对混凝土性能的影响。本文就着手研究用机制砂取代河砂对混凝土性能的影响。
Civil workers pay more attention to mixed material,like cement,water cement ratio,admixture and fly ash and silica fume and so on,in past studies.As an important part of concrete,aggregate occupies a very important position.With the development and perfect of civil construction,the natural sand is increasingly in short supply.So we should re-examine the influence of aggregate for the performance of concrete.This paper studies the influence of machine-made sand on concrete performance instead of river sand.
