Jan 30, 2020 · According to the “Code for design of concrete structures” (GB 50010–2010) , the standard uniaxial compressive stress–strain curves of OPC with strength grades of C30 and C50 were drawn and compared with the MOSC results, as shown in Fig. 9.
Early High Strength Concrete Advantages and Challenges
The concrete of the order of 200 Mpa has become a reality at least at the laboratory conditions and concrete of the order of M60 to M120 are commonly used at sites. The properties of the high strength concrete are well studied and understood by the engineers today, the use of very high strength concrete no longer raises eye brows.

CONCRETE - Boral
Mixing water in concrete. The use of too much mixing water in concrete is probably the most common abuse of concrete, and is often very costly. In a correctly proportioned concrete mix, only about half of the mixing water is needed to hydrate the cement. The remainder acts as a lubricant to produce workability.
