Grouting gradation characteristics - the largest particle size of aggregate and CGM high-strength non-shrinkage grouting material in zhengzhou

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material price, in contrast, aggregate in the grouting material is cheaper and won't produce complex chemical reaction with water, so often as a filler in the grouting material. In spite of the grouting material in aggregate accounts for 60% ~ 80% of its volume, there is also little sign of much attention to the aggregate effect on grouting material performance possible.             However, as people gradually realize the aggregate strength of grouting material, dimension stability and durability of important influence, the quality of the aggregate is gradually paid great attention by people. Aggregate in addition to affect these important properties of hardening of the grouting material, in determining the cost of the grouting material mixture, and also has important effect on the workability. Must therefore be as important as attaches great importance to the cement aggregate.             Aggregate has important significance for the preparation of grouting material features include: void fraction, grain size distribution, water absorption, grain shape and surface conditions, aggregate strength, elastic modulus, etc.             Grouting material quality worse than in the west in China, the main reason is that the quality of the aggregate. If you can't use enough including the smallest quantity of aggregate composition of slurry and the maximum amount of aggregate has needed a good construction performance of mixture, it is impossible to get good durability of grouting material. Aggregate quality first not strength, therefore, it is important to grading and grain shape, using a grading and grain shape good aggregate can get minimum water grouting material mixture.             Urban environment is the important symbol of the levels of management to measure a city luoyang grouting material, is also an important embodiment of city resident quality of life and level. On the one hand, a large number of construction waste, on the other hand, created, for the most part construction waste without any processing, by the construction unit to the suburbs or the countryside, with the method of open-air pile up or landfill, such not only takes up a large number of cultivated land, and takes up a lot of money.             In the process of transport and dealing with construction waste, storage, severance, and dust problems at the same time, such as the urban and rural secondary pollution. All in all, the phenomenon of 'garbage siege' impact of the construction waste of the city image and quality of life of their citizens, caused serious high-speed bearing grouting grouting material masterbatch environmental pollution. The building waste resource utilization, is becoming more and more important. Along with our country cultivated land protection and the implementation of various laws and regulations of environmental protection, how to deal with construction waste is not only the construction enterprises and the important subject facing the environmental protection department, and the whole society is unable to avoid the environmental and ecological problems.             At present, in the modernization of the important period in our country, in the old city transformation and the speed and scale of infrastructure, it will need a lot of grouting material, at the same time also produced a large number of abandoned grouting material, therefore, use of grouting material for regeneration of waste grouting material development and application of the grouting material industry in our country according to the circular economy development mode is of great significance.
