| Summary: | Foam concrete is lightweight concrete. It has been proven to be more environmentally beneficial than conventional concrete because it uses less natural resources. Besides, saving natural resources and making effective use of industrial waste as aggregate in concrete is a pressing issue. Currently, the effective use of industrial waste is of interest to many researchers. As a result, the current study seeks to investigate alternative fines sources by examining the impact of granular blast furnace slag as a substitute for sand aggregate on the properties of foam concrete. This paper builds on the author’s earlier research into the impact of blast furnace slag on the properties of foam concrete. In total, four foam concrete mixtures with densities of 1700 kg/m

and sand replacement amounts of 100% blast furnace slag were created. GOST has been used to measure the compressive strength, elastic modulus, and porosity of foam concrete. According to the findings, using blast furnace slag instead of sand makes foam concrete thicker and less porous. These findings result in higher foam concrete compressive strength and elastic modulus. Furthermore, the author used Hoff’s equation and Zheng’s equation to calculate theoretical porosity and compare it to observed porosity. The measured results indicate that the theoretical and measured porosity have a reasonably close relationship. |
