Hong jia star city high-rise construction - the application of concrete grouting material Zhengzhou grouting material manufacturers

grouting material grouting construction method grouting material models & # 8195; Hong jia star city is located in zibo city huantai zone in the zone and the project base on the east side of the high & # 8195; District administration center, on the west side of city park. Project is zibo first of large urban complexes with large construction scale, on behalf of the busiest one in zibo grouting material with fine sand international advanced way of life.             Hong jia star city construction of elevation, the mass concrete grouting materials mixed with fly ash, ground granulated slag powder, and improve the concrete grouting material performance; Can reduce grouting of concrete hydration heat, reduce or delay time wen appeared, to avoid reducing temperature crack; Of slag powder and fly ash mixed into the concrete grouting material, is the ideal combination of admixture.             For mass concrete grouting material, when 25% dosage of fly ash grouting material temperature influence of concrete is decreased obviously. When the dosage of 30% or more, than not mixing temperature to reduce 5 ~ 7 ℃. Are many standards and norms, under 25% dosage of fly ash in concrete grouting material, especially in the prestressed concrete grouting material content more strict restrictions, this is because, in China the past concrete grouting material beauty without mixed water reducing agent or concrete grouting material water-cement is bigger, in this case and then mixed with fly ash grouting material category, decrease the dosage of cement will make concrete grouting material time significantly slow condensation sclerosis, concrete grouting material low early strength, permeability increase.               High efficiency water reducing the seam an agent application nowadays is common, concrete grouting material water cement ratio, especially the concrete grouting material mixed with slag powder, water/cement ratio is easy to drop to zero. Below 5, at this point, it is suggested that in the prestressed concrete grouting material can be mixed with fly ash and is not affected by the span of henan grouting material manufacturers. ​
