Chuzhou, Laiwu grouting material - ready-mixed grout material powder slag 
 At present, the Chinese ready-mixed grout material mixed with the admixture to improve its performance. 
 Ready-mixed grout compound mixed with fly ash the most appropriate, in addition, the slag powder should be used as admixtures. 
 Slag powder with its own hydraulic and pozzolanic activity, because it is close to the Portland cement, but portland cement, the Cao low levels of the active poor, but in an alkaline environment in the cement water of product of Ca (OH) 2 and gypsum excitation, but has a higher activity. 
 Slag powder mixed with grouting compound, can not only improve the grouting material, the the Chuzhou grout bleeding segregation, workability, and can still improve the later strength of the grouting material; better than the slag powder content has become a powder The ash is applied after the second a wide range of mineral admixture. 
 Single powder slag grout earlier, to make the grouting material after the Blast Furnace Slag early strength, and fly ash mixed into the filling compound will be able to solve this problem, the complex-doped, and this is the role of promote each other, complement each other to produce the additive effect, are stronger than single doped any kind of admixtures, grouting materials, the Chuzhou grouting material strength higher contribution rate. In other words, fly ash + slag powder is not 1 +1 = 2, but 1 +1> 2, the technical effect. 
 Ready-mixed grout compound single Blast Furnace Slag, the slump of the grout material viscosity; Blast Furnace Slag and Fly Ash, on the one hand to improve the workability of the grout, but also to the grouting material strength complementary role to compensate for low early strength of the shortage of single fly ash. Slag powder and precipitation of Ca (OH) 2 can stimulate the activity of fly ash, thereby promoting the dissolution of fly ash particles of aluminum, silicon, so that the hydration liquid aluminum, silicon concentration increased, but also accelerated the slag powder the hydration process, various admixtures are involved in the hydration, of course, early, late, fast or slow, as long as the proper proportion, the superimposed effect of the functional admixtures in the grout compound will be able to meet the design requirements. Single Blast Furnace Slag grout, adverse the Chuzhou grouting material early Kanglie Star, the development and application of superfine slag powder should be cautious. 
 Slag powder content in ready-mixed grout compound should be based on the quality of the slag powder to determine the general dosage is: S75 grade of 10% ~ 30%, the s95 level for 20% to 40% of the S105 class 30% to 50%; slag powder influential Early Cracking of the grouting material, the content 20% to 35%, the grouting material early 3d autogenous shrinkage has little effect, but have a certain influence in the post-contraction, dosage 50% of early and late grouting material, Chuzhou grouting material autogenous shrinkage have a significant impact, so. High-strength concrete to control the dosage is less than or equal to 20% is appropriate. Ordinary grouting material single Blast Furnace Slag to 30% to 40% of the appropriate volume of grouting material can be increased to more than 50% can significantly reduce the heat of hydration of the grout. 
 Slag powder should be and Fly Ash can be improved grouting material contraction adversely affected. Blast Furnace Slag and Fly Ash suitable for the preparation of the grout, following the C45 the Chuzhou grouting material to the preparation of ready-mixed grout material of large size and the construction of the hot and the hot season is the best.
