What are some inexpensive materials that can replace cement?
I did research on the autoimmune disease Lupus. I discovered that there is an molecular compound called Silica in cement, and it seems to cause lupus; thus, I am wondering if there is a safer material that can be used that is about the same price as cement. #construction
