бетон Суперпластификатор ВСК Поликарбоксилатные Супе

Product Description The new generation of polycarboxylate superplasticizer has steric effect to cement particles spatially, thus it can prevent hydration of for a short time. That is because the main chains of the cement molecular are absorbed on the surface of cement particles while the branch chains are surrounded all around them. Its function principle is totally different from traditional water reducer of which to use electrostatic repulsion to exclude cement particles. It greatly helps to improve the quality of cement on strength, performance and permanence. Main Characteristics The unique comb-like structure of the polycarbonate superplasticizer makes the cement display advantages as follows:1 High water reducing rate: low dose but high water reducing performance; can significantly decrease water/cement ratio, and strengthren concrete at different ages.2 Good dispersibility and self-compactability: can compound different superfluity self-leveling concrete with different strength degree;3 Greatly improve the intensity of the cement during the early stage and the later stage, and strengthen the steel’s gripping force;4 Excellent slump value and high degree of staying power expansion, suitable for long distance transportation;5 Good adaptability to disperse and keep plastic of all kinds of cement and additives;6 Able to decrease carbonation rate, bleeding rate and the shrinkage and creep significantly;7 Free of chlorine and ammonia and low-alkali, no "three wastes" discharge during production; Homogeneity Index LiquidItemsIndexesItemsIndexesAppearanceYellow or pink liquidDensity1.06±0.02PH Value6 8Solid content20±0.5%Water-reducing rate20 40%Cl-contentNonePowderTest ItemsUnitsSpecificationMeasured ResultsWater-reducing Rate%≥2530DensityKg/m3≥520560Paste Fluiditymm≥280285 Application Applicable to all types of industrial and civil construction, water conservancy and hydropower, ports, transportation, municipal and other projects in situ, ready-mixed and pumped concrete, particularly has a special excellent performance in the early strength, ultra high strength, high permeability, such as self-compacting concrete. Usage and Precautions 1 The normal proportion to binder of concrete is 0.7% to 1.5%.If it is mixed with high strength concrete, the proportion may be increased to 2.5%.2 It should not mixed with naphthalene superplasticizer.Tests are required when it is mixed with other admixture.3 Please refer to interrelated regulations of GB50119-2003 abstract from< Technical code for application of admixture in concrete of China>
