At present, the main raw material for the preparation of mortar is not optimistic about the status quo. With the development of China's capital construction, construction of sand is increasing, many areas after decades of large-scale exploitation of natural sand resources are close to depletion, and the sand of the disorder and a large number of mining, destruction of the natural landscape and ecological environment, Also affected the embankment safety. On the other hand, China has made a lot of construction waste in the process of urbanization. Construction waste mainly includes the removal of old buildings and the construction of new buildings produced when the waste brick, waste concrete, waste mortar and construction dregs, etc., by jaw crusher crushing, shaker sorting, and then use sand making machine sand processing, Can be reused as a recycled aggregate resource. The waste concrete is sieved to form recycled aggregate, which not only can reduce the exploitation of natural gravel, but also can reduce the waste of concrete on the occupation of farmland and environmental pollution. At present, some of the construction waste crusher, sieved grading, the main use of which the coarse aggregate preparation of recycled concrete, and fine aggregate is not well used, construction waste crusher rate is very low. (Hereinafter referred to as recycled sand) partially or completely substituted for natural sand, used to produce known as the regeneration of mortar, the permanent savings of natural sand resources to reduce the solid waste on the environment pollution, Improve the green degree of building mortar, the development of circular economy has a very positive significance.
