Abstract:
Athletic concrete is lean, muscular and has great endurance with respect to long-term durability, increased abrasion resistance and decreased permeability, cracking and curling. This concrete is muscular in the sense that it has strong paste with a proper w/cm. High strength concrete, and floor slabs for various applications, from airports to commercial jobs to parking structures are discussed. Mixture proportioning designs provided
