Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] The present invention will be described in detail below in conjunction with examples.

[0019] Table 1 is the raw material ratio of the red facing mortar based on the wet-milled ultrafine red brick slurry of Examples 1 to 5 of the present invention and the raw material proportion of the comparative example (without adding the wet-milled ultrafine red brick slurry of the present invention material facing mortar). Table 2 shows the ratio of raw materials of the wet-ground ultra-fine red brick slurry in the red facing mortar based on the wet-ground ultra-fine red brick slurry in Examples 1 to 5 of the present invention.

[0020] The red facing mortar based on the wet-milled ultrafine red brick slurry of Embodiment 1 to Embodiment 5 of the present invention is specifically prepared by the following metho...

Abstract

The invention provides red facing mortar based on wet-milled superfine red brick slurry, which is mainly prepared by mixing and stirring the following components in parts by weight: 20-50 parts of wet-milled superfine red brick slurry, 25-40 parts of white cement, 10-45 parts of quartz sand, 5-10 parts of a water repellent and the balance of water. The red facing mortar based on the wet-ground superfine red brick slurry can effectively show the same effect as a red coloring agent on the market, in addition, the superfine red brick slurry can also greatly improve the pore structure of the mortar and induce nucleation to accelerate hydration, and the early strength is remarkably improved. The red facing mortar prepared by the method can be regarded as an effective means for improving the additional value of the waste red bricks of the building, and has an excellent popularization prospect in the construction waste treatment industry.

Description

technical field [0001] The invention relates to the technical field of utilization of solid construction waste, in particular to a red finish mortar based on wet-milled superfine red brick slurry. Background technique [0002] With the acceleration of industrialization and urbanization in my country, the discharge of solid construction waste is also increasing year by year. Since most of the demolished buildings were built in the 1980s and 1990s, red bricks were used in large quantities in these buildings, which also resulted in a high content of red bricks in solid construction waste. Newly generated construction waste exceeds 300 million tons every year. In 2015 alone, red bricks accounted for 50%-70% of the total solid construction waste in my country due to demolition, which exceeded the total construction waste. half of the amount. The treatment of these construction wastes is generally simple open-air accumulation or landfill, which will not only occupy a large amount...
