摘要
通过对机制砂进行化学成分检测,以不同氧化物含量将机制砂区分为高钙含量机制砂、高硅含量机制砂、高铝含量机制砂、高铁含量机制砂,四种机制砂在吸附性和与外加剂相容性等方面各具特点,根据每种机制砂的特性,调整混凝土外加剂组分,以改善混凝土的工作性能,使其满足工程质量要求。
Based on the chemical composition detection of artificial sand, the artificial sand can be divided into high calcareous artificial sand, high siliceous artificial sand, high aluminum artificial sand and high iron artificial sand. The four artificial sand have their own characteristics in adsorption and compatibility with additives. According to the characteristics of each artificial sand, the concrete additive components are adjusted to improve the workability of concrete and make it meet the engineering quality requirements.
