机制砂特性及其对混凝土性能影响研究现状

Characteristics of machine-made sand and research of its impact on concrete performance

大量开采天然砂会严重污染环境。机制砂是一种制作较简单、原材料获得较便捷的合成品,应用机制砂能有效避免环境污染,并降低建筑成本。机制砂中母岩岩性、颗粒特性、石粉含量以及MB值等会对混凝土的特性产生一定的影响。

It pollutes the environment to extract a large amount of natural sand.Machine-made sand is a synthetic product that is simple to make and convenient to obtain raw materials.The application of machine-made sand can effectively avoid environmental pollution and reduce construction costs.The lithology of the parent rock,particle characteristics,stone powder content and MB value of machine-made sand have a certain impact on the properties of concrete.
