Generally, limestone is 80%, and the remaining 20% is clay. In the cement plant, the raw mix is dried (moisture content reduced to less than 1%); heavy wheeltype rollers and rotating tables blend the raw mix and then the roller crushes it to a fine powder to be stored in silos and fed to the kiln.

7 Pigments (dry, natural, colored materials) are mixed in with the calcium carbonate while both are dry (the procedure is similar to sifting flour and baking powder together before adding liquid, as in a cake recipe). Water is then added to the mixture, which is then baked in the same manner as white classroom chalk.

The limestone powder and BFS are used to produce ECC in this research. The mix proportion is designed experimentally by adjusting the amount of limestone powder and BFS, accompanied by fourpoint bending test and uniaxial tensile test. This study results in an ECC mix proportion with the Portland cement content as low as 15% of powder by weight.

Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's mostconsumed resource.

Limestone powder (LS) has been widely used in cementbased materials; and reportedly, can influence their properties by filler, nucleation, dilution and chemical effects. The action mechanism of LS mainly depends on its particle size and amount. The filler effect of LS refines the microstructure and reduces the porosity of cementbased materials.

Hydrated lime also called slaked lime is produced when water is added to calcium oxide (CaO, or quicklime). The result of this mixing of water and calcium oxide (quicklime) is an exothermic reaction known as slaking. The slaking reaction produces calcium hydroxide, (Ca (OH) 2 ). Initially, the calcium hydroxide is produced as a fine dry powder.
