The purpose of this project was to evaluate two types of concrete surfaces and analyze the effect of each finish on the air content, paste content, aggregate fraction and rate of absorption at various depths from the surface. For this project, nine concrete mixtures were evaluated with varying cement, water and air contents. Slabs were cast and two types of finishes were considered: a trowel-finished made with a magnesium trowel and a form-finished from the plywood molds used. Cores were taken from the slabs and tested at 0, 5, 10, and 20mm below the surface.
