Optimization of cellular lightweight concrete using silica sand of sandblasting waste based on factorial experimental design
Sandblasting is a surface treatment that serves to clean the surface, improves adhesion strength and bonding performance, which in the process produces silica sand waste. Silica sand of sandblasting waste can be used as a lightweight concrete type of Cellular Lightweight Concrete (CLC). The experime...

Summary: | Sandblasting is a surface treatment that serves to clean the surface, improves adhesion strength and bonding performance, which in the process produces silica sand waste. Silica sand of sandblasting waste can be used as a lightweight concrete type of Cellular Lightweight Concrete (CLC). The experimental design was used factorial to find out factors influencing the compressive strength of lightweight concrete and to find the optimum composition of lightweight concrete with maximum compressive strength. The results showed that Portland cement composition and the ratio of foam significantly influenced the compressive strength of lightweight concrete with silica sand waste of sandblasting as aggregate. The optimum compressive strength of 86.13 kg/cm2 was found in the composition of Portland cement by 40%, silica sand 40% and volume ratio foam to mortar 0.6. |
