Large quantity of mineral powder reactive powder CGM high-strength non-shrinkage grouting material preparation idea Anhui grouting material price

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturers, large quantity of mineral powder preparation of reactive powder CGM high-strength non-shrinkage grouting material in accordance with the 'dense packing theory', get rid of coarse aggregate, optimizing the fine aggregate gradation, in ensure the premise of dynamic compaction, confirm the optimum mastic ratio ( The ratio of aggregate/gel dosage) And zhengzhou CGM high-strength non-shrinkage grouting material manufacturer by adding a large number of particles scattered outstanding alternative high dosage of cement, mineral powder in a large quantity of mineral powder reactive powder CGM high-strength non-shrinkage grouting material uniformity can be improved, make the large quantity of mineral powder reactive powder CGM high-strength non-shrinkage grouting material obtained relatively dense state, with proper hydration hardening conditions for high strength, and optimizing the dosage of steel fiber length to diameter ratio and improve the activity of large quantity of mineral powder powder CGM high-strength non-shrinkage grouting material brittleness. Large quantity of mineral powder reactive powder CGM high-strength non-shrinkage grouting material by reasonable selection of raw materials, optimization of grain size distribution, in the process of condensation sclerosis take appropriate maintenance molding process. Its design is based on the cut porosity, optimize the pore structure, improve the microstructure on the substance of its basic principles include the following points; 1, does not contain coarse aggregate, optimizing the fine aggregate gradation, improve the uniformity of the internal structure. 2, optimization of powder particle size distribution, using multistage size spread, compactness of progress. 3, optimization and active component compatibility of outstanding beauty high efficiency water reducing agent, to reduce the water cement ratio. 4, using steam maintenance, maintenance rules, such as dry and maintenance to improve its microstructure. 5, take part in the steel fiber, add CGM high-strength non-shrinkage grouting material toughness and volume stability. Large quantity of mineral powder reactive powder CGM high-strength non-shrinkage grouting material is a kind of multicomponent cement-based composites, the change of one component, is bound to affect the totality of CGM high-strength non-shrinkage grouting material performance, especially for the new mix CGM high-strength non-shrinkage grouting material fluidity and strength of hardened CGM high-strength non-shrinkage grouting material influence is more direct and clear.
