First, hydration tests were made on cement samples containing various percentages of Sodium Methyl Siliconate and Sodium Silicate. It was decided that it would be easier to determine what effect an additive would have upon concrete, if concrete blocks were actually made. Therefore, many blocks were made containing different amounts of various additives. Some of the concrete blocks were cut into cubes and slabs. The cubes were tested for their compressive strength. The slabs were tested for their resistance to corrosion from hydrochloric, acetic, and lactic acids. Some slabs were coated with certain substances to see if the coatings would offer more resistance to the acids. Portions of concrete blocks were formed and allowed to harden before more concrete was added to the surface. This was done with the intent of testing the strength of the joining of the two surfaces.
