CHAPTER 1 COMPONENTS OF CONCRETE

COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste. Aggregates are generally classi! ed into two groups, ! ne and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume.

Revealing the Mystery of Admixtures: Water-Reducing and

May 29, 2010· These are usually a two-component admixture system. The first component is a retarder (stabilizer) which delays the setting of concrete. The second component is an accelerator (activator) which overcomes the retarder. The concrete typically reaches initial set in a few hours after the activator is applied.

Chemical Admixtures Portland Cement Association

Retarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Retarders keep concrete workable during placement and delay the initial set of concrete.

Speciality Admixtures National Precast Concrete Association

May 29, 2010· Shrinkage reducing admixtures have two approaches to reducing shrinkage. Some cause expansion of the concrete to offset the shrinkage. These include finely divided iron and calcium sulpho-aluminate. Care must be exercised in that the expansion caused should not be disruptive to the concrete component.
