Grouting material performance factors and grouting material price

grouting materials and grouting material performance price relationship between grouting material prices high-strength non-shrink grout material factors affecting the durability of grouting material is more, there are mainly grouting material structure in the environmental conditions, the structure of the building function and the construction process of grouting materials used in the manipulation of the three factors. Meanwhile, the environment is the important factors influencing the structure durable function. Environment of a gas, liquid and solid diffusion, penetrate the grouting material with an inner, grouting material under the effect of these media, the physical and chemical changes will happen, sometimes is good, most cases will guide the grouting to hardening of the grouting material function deterioration in hangzhou. Grouting material structure in the environment category is divided into carbonation, chloride salt, chemical erosion environment and freeze-thaw damage and abrasion environment, etc. Advances the concrete measures of grouting material durability includes raw material selection, cooperation than late planning and structure planning, construction and protection, etc. The function of the cement, aggregate, admixtures for grout material has great influence on the durability, for weeks the goods should be carefully selected. As far as possible when planning of grouting material proportioning, cutting dosage of cement and water drop water thermalization, reduce cracks, compactness, choose reasonable water reducing beautiful seam an agent and air-entraining beautiful seam an agent, to improve the grouting material internal structure, with plenty of mixture, advance grouting material durable function; According to the use of environmental planning corresponding grouting material layer thickness, guard against the gas and liquid medium into the internal corrosion of reinforcement. Grouting material in the process of engineering construction should also consider the structure durability, grouting material mixing process should advance grouting material mix workability and cut water consumption; Casting vibrating mass grouting materials should control the temperature of the grouting material, shrinkage cracks and construction cracks, grouting material should be fully after casting for vibrating reasonably, advance grouting compactness and the permeability resistance, strengthen the maintenance, concrete grouting materials price cuts grouting materials crack in henan. Structure should pay attention to in using the phase detection, protection and repair, the infrastructure under outdoor and harsh environment Dali grouting material engineering. To sum up, the performance of the grouting material and grouting material price has a little relationship, even grouting material price directly determines the performance of the grouting material!
