Effect of Dolomite Limestone Powder on the Compressive

Jan 01, 2013 As we can see, partial cement replacement with dolomite limestone powder results in compression strength increasing. Strength of samples containing 25% of dolomite limestone powder increased by 16.7% and 23.5% at 14 and 28 days age, respectively, in comparison with

The Effect of Dolomite Additive on Cement Hydration

Jan 01, 2015 At low percentage dolomite plays a role of cement replacement; at higher dosage the „dilution” effect can be observed. However, increasing dolomite content is accompanied by higher amount of hydration products, as a results of crystallization on the fine dolomite grains and better absorption of water.
