Concrete Chemical Admixtures

Admixtures related to moisture control (called water-reducing admixtures) generally consist of additives that allow for concrete to retain its workability given a water content lower than that of typical concrete. Reducing the amount of water in a concrete mix will generally cause an increase in strength; however, in unmodified concrete (no

Using Admixtures to Improve Chemical Resistance of Concrete

Air-entraining admixtures improve sulfate resistance, primarily because air entrainment permits a reduced water-cement ratio that decreases permeability. ACID ATTACK. Because no portland-cement concrete is totally immune to acid attack, admixtures can be used only to slow the rate of deterioration.

Properties and Uses of Different Types of Concrete Admixtures

Air entraining concrete admixture: Air entraining concrete admixtures produce tiny air bubbles in the hardened concrete to provide space for the water to expand upon freezing. How do they work? They are anionic (water-hating) agents that form tough, elastic, air-filled bubbles. These bubbles reduce stresses caused by movement or freezing of water.

Superplasticizer - Wikipedia

Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent.
