HSC Polycarboxylate Based High performance water r

concrete admixtureHSC Polycarboxylate Based Hihgperformance Water-riducing agent is a new generationof high performance water reducing developed by the company. Concrete incorporated of this product can maintain slump retain walue which has basically no loss of 0.5 hour and minimal loss of 1 hour.It has the characteristics of low dosage of admixture,high water reducing rate,small shrinkage and so on at the same time. Concrete mixed with the product can improve the slump flow,maintain workability for a longer time;that also can improve the workability and mechanical properties so as to enhance architecture project quality.inspection itemPerformance indicatorsinspection findingsWater-reducing rate,%20 min25Ratio of bleeding at the normal pressure,%20 max0Ratio of bleeding at the pressure,%90 max45Ratio of compressive strength,% 3d 130 min1727d 125 min16628d 120 min153Effect of corrosion of reinforcing steel bar No corrosionNo corrosionRatio of shrinkage,% 135 max97Index of relative durability,%,200times 80 min85Notations:These kinds of products are converted into solid content of 20% calculated.The dosage is cementitious material content of 1.0%;Product Advantage:Low dosage, high water reducting, and small shrinkage.the chloride and alkali content of the product is low,that conducive to the durability of concrete.he production process of non-polluting, non-formaldehyde match the requirements of ISO 9001 Environmental Management,that is green environmentally friendly products.Especially suitable for the projects which need long hours to prepare the concrete construction and maintain high requirements on the concrete slump,for example nuclear power engineering.Usage:Compliance dosage: In general, when discounting solid dosage 20% the dosage is 0.5% to 1.5% of the weight of cementitious materials. Compliance dosage is 1.0%Storage : At low temperature this product may have the solidified phenomenon. However, after heating and mix well,it can restore the original performance.
