conforming to jc473-2001 standard of "concrete pumping agent" [ applicable range ] : 1. applicable to pouring or prefabricating, prestressing reinforced concrete as well as breeze-admixed concrete. 2. applicable to preparation of various strengthened high-performance concerns, self-sealing, pumping concrete as well as gravity flow grouting materials 3. having good adaptability to silicate cement, common silicate cement, slag silicate cement, breeze silicate cement and pozzuolana silicate cement. [ main performances ] : 1. xp-302-type liquid product enjoys the appearance of brown liquid without toxicity, odor, corrosion to the steel bas with the density of 1.18±0.02g/ml. 2. this product enjoys the water-reducing rate of above 15% with the using quantity and slump not changed, and can elevate the one-day strength by 15-250%, three-day strength by 25-40% and 28-day strength by above 30% and considerably improve and elevate various physic performances of concrete. 3. it can significantly increase the slump of concrete by 1.0-1.5 times and improve concrete. 4. it can save cement by 10-15% with slump and strength not changed. [ recommended admixing quantity ] : 0.7-1.2% (calculated as the total of cement or cementing materials) [ use method ] : this product can be directly put into the mixing water for concrete or added into the concrete at a subsequent stage. [ matters needing attention] : sealed in clean containers for preventing leakage and dryness on evaporation. |
