火山岩应用于水泥基材料的现状与展望

A Review of Resource Utilization of Volcanic Rock in Cement-based Materials

本文介绍了火山岩的来源、化学成分、矿物组成及分类方法,以及火山岩和由火山岩磨细制成的火山岩粉在水泥基材料中的应用研究、在实际工程中的应用情况。火山岩本身具有较高硬度,可直接作为骨料使用,而磨细后制成的火山岩粉具有一定的火山灰活性,可作为一种绿色低碳的天然火山灰质材料使用。虽然在部分地区火山岩粉已成功应用于工程实际,但其理论基础及应用技术仍存在不足,不同地区的火山岩由于成岩条件和成岩年代等的不同,其性能存在较大差异,有待更加深入的研究。

This paper mainly introduces the application research of volcanic rock and volcanic powder made from volcanic rock grinding in cement-based materials and the general situation of application in practical engineering.Volcanic rock has high hardness and can be used directly as aggregate,while the volcanic powder made by grinding has certain pozzolanic activity and can be used as a green and low-carbon natural pozzolanic material.Although volcanic powder has been successfully applied to engineering practice in some areas,the theoretical basis and application technology are still insufficient.Due to the difference in diagenetic age and conditions,the macroscopic properties of volcanic rocks in different areas are quite different,and more in-depth research is needed.
