    Accelerating admixtures added to a standard mix, without changing the cement or water content, increase th e rate of hydration thereby increasing the early strength but reducing the ultimate strength. Use of chloride based admixtures for reinforced concrete is not recommended. Increasing the cement content 30% produces high-early strength concrete.
