Concrete expansive beautiful seam an agent is the national standard GB 23439 - 2009

Concrete expansive beautiful seam an agent of concrete expansive beautiful seam an agent price concrete expansive beautiful seam an agent manufacturer concrete expansive beautiful seam an agent is a kind of low alkali, my company production of low dosage of high performance concrete expansive beautiful seam an agent, the same kind of concrete expansive calcium sulphoaluminate beautiful seam an agent, but the performance is more stable, grain size distribution is more reasonable, the performance of its expansion cement hydration system after development and turn the more matches. In the concrete mixed with the expansion of the cement dosage 8 ~ 10% beautiful seam an agent, can compensate the shrinkage of concrete, improve the crack resistance of concrete anti-seepage ability, make it become the excellent waterproof impermeability of concrete. Main use: preparation of compensating shrinkage, joint filler, used for crack resistance and permeability structure since the waterproof, pool and rigid waterproof roof engineering; Self-stressing concrete, used for cement products. Mechanism: concrete expansive beautiful seam an agent is an ideal material to compensate shrinkage, dry shrinkage and temperature shrinkage is the main reason. Added to the concrete, the mix water generated after a large number of swelling crystallization water compound, make its produce moderate inflation, under the constraints of reinforcing steel bar and ortho, produce expansion can be converted to compressive stress, the stress can offset the contraction in the hardening concrete tensile stress, and thus reduce the cracks. Permeability seam an agent is mainly to improve their dense and add water, to meet its permeability resistance and impervious. But due to concrete shrinkage and shrinkage stress caused by, enough to make the structure deformation, and cracks. Due to the crack makes concrete waterproof lost a more fundamental security. The main reason for the leakage of the building. Pore filling crystal and the emergence of internal concrete close-grained, improve concrete anti-seepage acid resistance, alkali resistance, resistance to chemical attack and micro expansion ability, this beautiful seam an agent to expand the seam an agent, waterproof beauty seam an agent of the indicators. A kind of plastic phase of the double effect of expansion and hardening period, fully compensate shrinkage of concrete, small dosage and combined expansion, reduction, water seepage, crack composite functions such as concrete and beautiful seam an agent. It in a certain proportion of mixed with concrete or mortar, can be produced under the condition of limited expansion stress, thereby shrinkage compensation, to prevent concrete cracks, improve the permeability resistance of concrete. And can amount to replace cement, and had no any bad effect on steel stick relay for reinforcement corrosion. Method of use: concrete expansive beautiful seam an agent dosage is 10% ( In order to cement meter) To demand higher impermeability and crack resistance of concrete, increase dosage can test. Before the initial set of concrete should be in accordance with relevant rules of construction, repeatedly put pressure on concrete surface to prevent dry, avoid caused cracks, settlement after the final set, curing, curing period shall not be less than 12 days. This beautiful seam an agent to the site should be with local cement after test in use.
