TABLE OF CONTENTS High early cement does exactly what its name implies: it provides higher compressive strength at an earlier age. Although Type III or Type IIIA cement can produce high early strength, ther are other ways to achieve the same end result:
Add more cement to the mixture [600 lb (272 kg) to 1000 lb (454 kg)];
Lower the water content (0.2 to 0.45) by weight;
Raise the curing temperature after consultation with the design engineer;
Introduce an admixture into the design mix;
Introduce microsilica, also known as silica fume, to the design mix;
Cure the cast-in-place concrete by autoclaving (steam curing);
Provide insulation around the formed, cast-in-place concrete to retain heat of hydration.
