【 摘 要 】

In this paper, the recycled aggregate that is made from light red volcanic slag and abandoned concrete is used as a coarse aggregate, while fly ash and calcined diatomite are used as cementing materials in order to replace part of the cement. The mix proportion of lightweight aggregate concrete made from volcanic slag is designed and tested. A new type of lightweight aggregate concrete hollow block with volcanic slag has been developed by means of the pore structure of the main design, and the revised formula of the compressive strength of the concrete block was obtained by regression analysis of the compressive strength test results. The block has the advantages of having an excellent compressive strength, good thermal conductivity, low cost and so on.
