Building grouting material: the effect of grouting material carbonization and multiple factors have? - Fuzhou grouting LiaoChang

grouting construction of grouting material specification grouting material & # 8195; 1, reduce the alkalinity grouting material, reduces the protection of reinforcement, equipment foundation grouting material manufacturers.       2, cause systole of grouting materials, grouting material surface could produce micro crack, tensile and flexural strength decline.   3, the hydration products of cement decomposition & # 8195; 4, the grouting material compressive strength improved & # 8195;           A, the external environment influence carbide & # 8195;           1, the concentration of carbon dioxide. The higher carbon dioxide levels will be accelerated carbonation, in recent years, industrial emissions of carbon dioxide amount continue to rise, the urban construction speed in the accelerating carbide grouting material structure.             2, environmental humidity. Water is necessary condition for the grouting material of carbonation reaction, the relative humidity was 50% ~ 75%, the grouting material baidu encyclopedia carbide fastest.               Second, the grouting material carbonization internal factors & # 8195;             1, cement varieties and dosage of admixture. In the grouting material with Portland cement clinker composition of gelled material system to reduce, an increase in the amount of admixture, carbide was accelerated.               2, the compactness of grouting material. With the decrease of water/cement ratio, porosity, water and carbon dioxide gas is not easy to spread to the grouting material internal, carbide at a slower pace.               Building materials confirmed for large grouting material with high content mineral admixtures is key depends on carbonation speed and depth of the mineral admixtures of pedestal grouting material masterbatch adding ratio and water/cement ratio and the matching construction curing. ​
