Figure 9 compares the test results of a 30% replacement limestone powder to the control. There was an average reduction in shrinkage by % at 28 days, and at the early ages of the specimens. Particle size of the limestone powder still had little effect on shrinkage, even at a larger volume of limestone powder used to replace cement.
Full Answer. In nature, marble, limestone and chalk contain calcium carbonate. By processing calcium carbonate from marble, one obtains precipitated calcium carbonate, which is ground into a powder called ground calcium carbonate. Ground calcium carbonate has many industrial, medicinal and pharmaceutical uses. In the construction industry,...
