Plastic expansion beautiful seam an agent variety and performance

Expand the seam an agent plastic expansion the seam an agent USES the seam an agent can be divided into four categories according to chemical composition: calcium sulphoaluminate classes; - calcium sulphoaluminate Calcium oxide classes; Calcium oxide classes; Magnesium oxide class. 1. Class calcium sulphoaluminate expansion beautiful seam an agent of such beautiful seam an agent to hydration calcium sulphoaluminate ettringite as the main source of inflation. Have U - kinds representative 1 the seam an agent, U - 2 the seam an agent, u-shaped efficiently expand the seam an agent, CEA composite expansion the seam an agent, AEA expansive beautiful seam an agent, alunite expansion beautiful seam an agent, magnesium oxide expansive cement. 2. - calcium sulphoaluminate Calcium oxide class expands the seam an agent, it refers to the water mixing cement, the hydration reaction to generate calcium hydroxide beauty of concrete expansive agent. For EA beautiful seam an agent, Also known as CEA, composite expansion seam an agent) On behalf of, expansion source to Ca ( 哦) 2 is given priority to, ettringite ( 3CaO·Al2O3·3CaSO4·32H2O） As the time, CaO are about 70% of the chemical composition. 3. Magnesium oxide as the delay of expansion source micro expansive cement periclase powder was used as a kind of expansion source blending directly to the mixing of concrete and the seam an agent has not been very successful, because of the quality of the periclase is difficult to control and mixing unevenness and abandoned. The new expansion the seam an agent - - Plastic expansion the seam an agent, low dosage, dosage is small, details could consulting the - 13213116342.
