Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
It was stronger than Portland cement but its poor water resistance and corrosive qualities limited its use in building construction. The next development in the manufacture of Portland cement was the introduction of the rotary kiln, which produced a stronger, more homogeneous mixture and facilitated a continuous manufacturing process.

Replacement of cement with dolomite powder is found to improve the strength of concrete. The maximum replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 5.84% and 2.73% respectively.

The water cement ratio should be based on the total cementious materials, i.e., the portland cement plus the fly ash substituted. Substitution ratios of a minimum of 1 to 1 on a mass basis with a maximum substitution should be specified. A substitution rate of 15 to 25 percent is currently being specified for typical concrete production.
