Ready mixed mortar is a new building material, in the construction industry plays an extremely important. It is reported that, in the construction process, the use of on-site mixing mortar not only produce a lot of dust and noise pollution, the environment of the city, resulting in waste of raw materials and artificial materials, due to the use of measurement error, and easily leads to unstable quality of affecting the quality of construction engineering. The ready mixed mortar with stable quality, high construction efficiency, less dosage, is conducive to saving energy and reducing consumption, to ensure the quality of the project.
City construction site the use of ready mixed mortar is of great significance for mixing mortar, is not only to ensure the construction quality, improve the level of modernization of the limited measures of construction engineering, is an important means to realize the comprehensive utilization of resources, the implementation of the construction of civilization. Ready mixed mortar mixing mortar has become an inevitable trend to replace.
Mortar production requires a lot of fine aggregate, and mining down from the tailings of limestone or cement factory is a very good material, only the tailings after crushing and screening, the granularity is required for the production of ready mixed mortar requirements change. It must be used to sand making machine, the third generation of new sand making machine was equipped with the first sand production line of SBM Technology Co., the company successfully launched the tailings sand equipment ideal. It is understood, the third generation of sand making machine adopts SBM patented "stone dozen stone" of the crushing process, the formation of many closed loop in the broken link, the breaking out of uniform particle size, crushing rate, avoid the waste powder, is a high efficiency and energy saving, the coarse fine grinding equipment the use of ready mixed mortar, in the granite, goose warm stone, gypsum, Xuan Wuyan stone, is also very suitable. The particle size of finished products fully meet the requirements of ready mixed mortar with mineral, so as to ensure the water retention and bond strength.
In addition to foot material and construction waste, tailings, coal gangue, slag and other industrial solid waste in preparing ordinary mortar is a very good material. In recent years, more and more city has introduced a series of policies, and vigorously promote the use of ready mixed mortar, to prohibit on-site mixing mortar will produce the enormous economic benefits and social benefits in the urban area.
