superplasticizer

DLS19 superplasticizerFirst. Introduction DLS-type superplasticizer is that our company developed new products environmentally, the product is the main carbonyl compounds, under alkaline conditions it develops certain molecular weight polymer with formaldehyde, and open the carbonyl through sulfonation, introduce hydrophilic sulfonic acid groups, so that the surfactant molecules have the characteristics of a polymer superplasticizer. Product is a green product without ammonia, formaldehyde and other harmful substances, with no chlorine, low alkali, high water reducing rate, high fluidity, early strength, enhanced and slow setting characteristics, minimal slump loss, it also can reduce the cement the amount of concrete and reduce the water-cement ratio, lower heat of hydration, improve resistance to high temperature difference between cracks in concrete ,improve the mechanical properties and durability of concrete effect. Especially for ready-mixed concrete, pumping concrete, can be used in high-rise buildings, ports, bridges, roads, airports, water conservancy, electricity and other concrete projects.Second, product performance 1, the product is brown-red viscous liquid, solid content of 35%, PH value is 8-10 2, reducing the water rate, the liquid content of 1.5% -2.5%, less 21% -30% water 3, low alkali content, into the concrete alkali content of 0.53 per side 4, does not contain formaldehyde, ammonia, benzene and chlorine ions and other harmful substances, no corrosion of the steel plat 5, performance testing results are as follows Test itemsPerformanceTest resultsIndividual assessmentWater reduction rate%≥1025QualifiedBleeding rate%≤9524.2QualifiedGas conten%≤4.02.8QualifiedSetting time differenceminInitial setting-90-+120+108QualifiedFinal setting+99QualifiedCompressive strength rate %ID208Qualified3D174Qualified7D183Qualified28D171QualifiedShrinkage ratio %≤135115QualifiedEffect on steel corrosionShould indicate no damage to the steelNoQualifiedNotes1,42.5 for the Portland cement binder 2,Admixture content is 1.5% × Cthird,product quality indexProjectIndexAppearanceViscous liquidSolid content35%ph8-10
