Premium Quality Polycarboxylate Superplasticizer as Concrete Water Reducer

Premium Quality Polycarboxylate Superplasticizer/PCE For Concrete Water Reducer  This product is a new generation of environmentally-friendly polycarboxylic acid high-performance hydrazine type water reducing agent developed by our company. Under the alkaline condition, the hydrazine type itself undergoes hydrolysis reaction, thereby releasing carboxylic acid groups with dispersing properties. Achieve a long-lasting dispersion effect, in addition to excellent sealing performance, it also has a certain water reducing effect, and significantly improves the cohesiveness of concrete and improves the concrete performance.Product technical performance1. Special molecular structure and special branch structure design, which is used for hydrolysis reaction in fresh concrete. By adjusting the branch structure, the hydrolysis rate can be adjusted within the effective time to achieve selective protection effect.2. Slow release property,This product is blended into concrete, slowly hydrolyzed, releasing carboxylic acid groups to achieve long-lasting dispersion effect, achieving ideal preservation effect.3. The higher strength increase rate, the concrete mixed with the product does not change the setting time, overcomes the shortcomings of the general retarder to make the concrete final setting time too long, and the early strength development is too slow.Product Usespce slump retention type concrete water retaining agent polycarboxylate superplasticizer can be used for precast concrete,SCC concrete,ready mix concrete,self-leveling mortar,etc.concrete test for your reference Standard testing=1.2 g PCE + 87g Water + 300g CementDosage of 50% PCE % Ratio of Water reducing %(at least)0.03: 28-30 0.35: 28-300.4 : 320.45: 320.5 : 32-400.6 : 35-40Weight of PCE Dosage=Dosage suggested * (Weight of cement + fly ash + mineral )(50% mother liquid) tested by Shanlv P.O.42.5 ordinary portland cement,with the dosage of 0.32%   CL-SR-50:CL-WR-50=4:687g water+0.96g CL-50+300g cementtime(min)slump variation retentionstate30min240mmrising60min280mmmax120min280mmmax180min260mmlostScope of applicationThis product is especially suitable for various water conservancy, port, transportation, bridge, subway, electric power, etc., and has various high performance requirements for concrete slump.After compounding with carboxylic acid, this product is suitable for high-strength, high-performance, high-durability super-flow vibration-free self-leveling, self-compacting and steel fiber and other special concrete, subway tube, slag-free sleep rail and other precast concrete and long-distance transportation. ConcreteInstructionsThe recommended range of product is 0.35%~0.65%. The specific amount of cement and mix ratio should also be determined by experiment.This product has a low water reduction rate and is recommended for use in combination with a water-reducing mother liquor. The optimum compounding ratio should be determined according to the test. This product can be combined with various functional admixtures such as polycarboxylate water reducer and various retarder air entraining agents. The best compounding should be determined through experiments before use.PrecautionsThis product is an alkali-free liquid, non-toxic, non-corrosive liquid, no pollution to the environment, not edibleIf you accidentally touch your eyes, rinse them with clean water as soon as possible, causing allergies to some people.
