Concrete Slab with Fiber Mesh or Wire Mesh Reinforcement. For a 12×12 exterior slab .I advise 4″ of compacted stone subgrade, wire mesh, no fiber, low slump concrete, air entrained, 3,000 psi mix, and soft cuts creating a foursquare pattern. The slab will definitely crack on the foursquare lines but you will have done all you could.

Jun 26, 2006· Strength You can achieve much higher compressive strength with concrete mixes than gypcrete. Gypcrete, under ideal conditions, barely meets the recommended strength that the engineered wood floor guys require (3,000 psi or so) for glue down (but I hear this recommendation is being revised downward to 2,500 psi).

Nov 09, 2005· CounterFlo Concrete Countertop Admixture, an admixture from FritzPak Corp., is intended to solve that problem. It's a water reducer designed for use when creating concrete countertops and statuary. It helps concrete maintain an adequate flow rate with less water, allowing a contractor to lower the amount added to a mix.
