Slag can increase late age strength of concrete, but impairs the concrete earlyage strength due to low reactivity. Limestone powder can increase earlyage strength, but impairs lateage strength due to dilution effect. The combination of slag and limestone powder can produce a composite concrete with adequate strength at both early ages and late ages. This study shows an integrated hydration ...

Plain cement concrete (employed as reference) and three concretes containing limestone powder (replacement ratios of 10, 20, and 30%) were designed. The compressive strengths of the four concretes were close to each other by adjusting the water to binder ratios. The longterm (as long as 5 years) properties of hardened paste and concrete were determined under the condition of equal 28day ...

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.

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.
