Q: How will the new cements affect visual concrete? A: The recommendation for visual concrete is that a minimum of 350kg/m 3 of fine material (less than 125µm) is needed within the concrete. The fine material would include cement, fine material within the sand and any fine filler material used such as limestone fines or pigments.
