Grouting material selection of aggregate vital do you understand? - Henan zhengzhou grouting material

CGM grout CGM grout material manufacturers in henan zhengzhou grouting material manufacturer aggregate is an important part of henan zhengzhou CGM grout material, CGM grout material hengshui henan zhengzhou in henan zhengzhou CGM grout material manufacturers throughout the volume, aggregate accounts for at least three quarters, so aggregate in grouting guess occupies very important position. Many properties of aggregate determines the henan zhengzhou CGM grout material rheological feature of mixture and hardening mechanics function of the henan zhengzhou CGM grout and durable function. Aggregate and cement stone has virtually no effect each other, but when the change of aggregate mixture rate of space, make henan zhengzhou CGM grout material volume filling rate changes, as well as the aggregate and cement appearance features and cohesive force changes, they will have corresponding influence, so as to cause an effect to henan zhengzhou CGM grout material function. Aggregate and cement interface is the weak link grouting guess, henan zhengzhou CGM grout material integrity, durability of permeability and often depends on the size of the aggregate and matrix ratio, aggregate gradation, aggregate diameter, elastic modulus, grain shape and appearance structure, the function of henan zhengzhou CGM grout material has a great influence. Green high functional henan zhengzhou CGM grout material choice of aggregate should consider the following aspects: & amp; Henan zhengzhou CGM grout material shelf life where reflect have spent A, aggregate volume rate of henan zhengzhou CGM grout material mixture slump along with the adding of aggregate volume rate drop, aggregate, rarely in the suspended state matrix, henan zhengzhou CGM grout material rheology and similar to that of cement matrix, so the henan zhengzhou CGM grout material slump is larger, with aggregate amount to add, cut the number of slurry matrix of lubricating effect, aggregate overlap each other, the flow resistance increases, mixture slump. Second, the aggregate grain shape of the aggregate particles of high strength of henan zhengzhou CGM grout material roughness per cubic tonnes of any shape and appearance of new mix of henan zhengzhou CGM grout material workability and hardening after henan zhengzhou CGM grout material has a great impact on the mechanical properties; More ambitious coarse aggregate particle shape is close to the sphere or regular polyhedron. Third, aggregate - Substrate bonding strength between matrix and aggregate looks bonding degree is related to many factors, which are mainly; Kinds of categories and appearance characteristics of aggregate and cement fineness, henan zhengzhou CGM grout material mix workability, compactness and maintenance criterion, etc. General thought; Appearance of concave and convex rough, the combination of angular particles aggregate and cement, lubrication of aggregate is more strong than appearance.
