The definition and characteristics of efficient crack-resistance waterproofing agent

High crack-resistance waterproofing agent set the essence of the numerous concrete expansion agent, using parts imported gelled material and polymer technology, not only has high efficiency expansive agent of anti-seepage anti-cracking performance, also has a water reducing, strengthen, low alkali, plasticity is good, good construction workability, frost resistance, corrosion resistance, etc. It is a kind of CaO - HgO - A12O3 - SO3 four system of high performance concrete crack-resistance waterproofing agent. Fuzhou high crack-resistance waterproofing agent features: 1, the work performance is good: retarded water reducing, retention of the plastic can be good, good workability, slump loss is small, suitable for commercial concrete and field pumping concrete. 2 percolating-proof properties, and high expansion efficiency, and anti-permeability label is greater than the S30, compensating shrinkage crack seepage control performance is superior to the common waterproofing agent. 3, to reduce the hydration heat, delay the peak of hydration heat and contraction starting time, thus reduce shrinkage of concrete temperature and prevent the crack of concrete structure. 4, using SMAC, don't need and other chemical admixtures, less operation process, reduce errors, it has good compatibility with cement, concrete mixing plant and field use. 5, low dosage, high performance. General type of concrete expansive agent adding amount of 10 - 15%, SMAC just 4 - 8%. Its unique advantage is: expansion energy, silicate erosion resistance, the late dry shrink, concrete strength is high, low dosage, low alkali content, without JianJiLiao reaction were evident; Has good compatibility with all kinds of admixtures, had no effect on the early concrete performance; Percolating-proof function, it has excellent is a safe, good durability and percolating-proof type high performance concrete admixture. 6, low alkali content. SMAC is the present domestic all kinds of concrete expansive agent alkaline minimum expansion agent is a kind of high performance.
