Concrete Technology Portland Cement Association

In its simplest form,concreteis a mixture of paste and aggregates (rocks). The paste, composed essentially of portlandcementand water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known asconcrete.

Emerging Trends Portland Cement Association

Adding optical fibers to aconcretemix generates translucentconcrete. This “see-through” development is changing the perception ofconcrete’sopaque mass. Reactive powderconcreteis extremely workable, durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30,000 pounds per square inch (psi), thisnew-age concretealso has tensile strength with the …

The Cement Manufacturing Process Advancing Mining

The clinker is ground to a fine powder in acementmill and mixed with gypsum to createcement.The powderedcementis then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of thecement.Excess free lime, for example, results in undesirable effects such as volume …

How do I obtain highearlystrengthconcrete

Highearlystrengthconcrete(2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-earlystrengthcement(see Table 1), highcementcontent (600-1000 lb/cu yd), and lower water-cementratios (0.3 to 0.45 by weight). Super-plasticizers are also used to make theconcretemixture more workable during placement.
