Quality of Water used for Concrete Mixes-Concrete Technology

2017/08/28 · It is found that the mixing of sea water causes the lesser strength and corrosion to the reinforcement in concrete.The mixing of seawater in non reinforced concrete can be adopted. The sea water mixing results increase in strength at 3 days, but 28 days of strength is comparatively less( reduces about 15 percent of its strength).Also, the required strength can only be achieved by redesigning the mix.

How to calculate cement, sand and coarse aggregate for concrete?

Concrete Material Calculation. For the above slab volume ( 5m x 2m x 0.1m) = 1 m 3. We need 1 m 3 of wet volume concrete of M20 Mix, (Mix Ratio, M20 = 1: 1.5 : 3) So Total Parts = 1+1.5+3 = 5.5 Parts which gives Dry volume that means before adding water content. We have discussed the effect of water on concrete. Adding Void Ratio Compressibility
