High Cement Content

High early strength concrete can also be formed with the growth in cement content (400 to 600 kg/m3).

Low Water-cementing Materials Ratio

The cutback of water to cementing material that varies from 0.20 to 0.45 by mass can also develop high-early-strength concrete. To form high-early-strength concrete, water to cement material ratio should remain 0.32 to 0.42 while the application of w/cm of 0.20 can develop very-high-early-strength concrete.


Greater Freshly Mixed Concrete Temperature

When the temperature of freshly mixed concrete is raised, hydration of cement also enhances. Therefore, the growth of newly mixed concrete temperature would enhance the process of strength development in concrete, and consequently high early strength concrete is produced.

Chemical Admixtures

Accelerating admixtures are also useful for developing high-early-strength concrete. As for instance, calcium chloride standardized by (ASTM D 98), is an accelerating admixture that can form high early strength concrete. The accelerating admixture enhances the rate of hydration of concrete as well as early strength development of concrete.
