Admixtures for ready-mixed concrete, prefabrication, architectural concrete Admixtures for concrete mainly include plasticizing, fluidizing, retarding (delaying) or accelerating bonding, aerating, and sealing preparations. Currently, you can find on the market a wide range of admixtures for concrete. Their consumption is constantly increasing. One of the admixtures is a plasticizer, which significantly reduces the surface tension of batched water and plasticizes the concrete mix. Superplasticizer is a type of admixture for concrete, which causes the formation of a double ion layer around the cement grains, which reduces the friction forces, intensively disperses cement paste, and liquefies the concrete mix. Admixtures for concrete perform in many other functions. They reduce water demand of the components of the concrete mix, increase ultimate compressive strength, and improve concrete frost resistance. A big advantage of concrete admixtures is also the improvement of concrete appearance, which is of great importance for the architecture of the entire facility.
