PERFORMANCE OF HIGH STRENGTH CONCRETE –

The cement paste matrix in high-strength concretes is dense owing to the absence of large capillary voids and a relative strong aggregate-cement paste interfacial zone, which has a much lower tendency for micro-cracking. High-strength concretes contain relatively high binder material content, a super plasticizer, and very low water content.
