It can be seen from Fig. 4, Fig. 5, Fig. 6 that concrete made with Type II and Type V plain cements is more resistant to seawater attack as compared to the Type I plain cement. The effect of seawater attack on concrete was studied using fly ash at 0%, 10%, 20%, and 30% replacement for Type I, Type II, and Type V Portland cements.

A concrete without reinforcement steel is called Plain Cement Concrete (PCC). Design mixes commonly used for PCC are 1:4:8, 1:3:5, 1:2:4, M7.5, M10 etc. Plain cement concrete is high in compression and very low in tension.

For 1m3 of wet or solid Plain Cement Concrete (PCC) ratio (1:3:6), we have to multiply with factor 1.52 for dry density than 1m3 become 1.52m3 of cement, sand & aggregate is required, due to presence of voids in sand in dry state. So, cement sand and aggregate quantity is calculated for 1.52m3 of PCC. Dry volume = 1.52 m3.
