Abstract

A method for making brick powder concrete from waste sintered shale brick powder comprises the following steps: (1) impurity removal; (2) crushing and drying treatment; (3) grinding, sieving and drying treatment for obtaining the waste sintered shale brick powder; (4) weighing of the following raw materials: cement, medium sands, cobblestones, water, the waste sintered shale brick powder, magnesium borate, zirconia, hydroxypropyl methylcellulose, bentonite and mica according to corresponding parts by weight; (5) oscillation stirring of the raw materials with 100-200 Hz ultrasonic waves to obtain a mixed slurry; and (6) molding of the mixed slurry. Sintered shale bricks which are wastes are processed to form the powder, and the powder is used for partially replacing the cement to produce the brick powder concrete, and the integral performances of the brick powder concrete are effectively better than those of ordinary concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a method for making brick powder concrete by using waste sintered shale brick powder. Background technique [0002] Concrete is one of the fundamental materials widely used in the civil engineering industry. According to the statistics of the National Bureau of Statistics, my country's commercial concrete output in 2016 reached 1,792 million cubic meters, an increase of 7.4%, and an increase of 5.4 percentage points year-on-year. With the rapid economic development, the application of concrete is more and more extensive. Every day in our country, old buildings are demolished and new ones rise. As a result, a large amount of construction waste will be generated every day. Abandoned sintered shale bricks account for a large part of construction waste. At the same time, shale brick manufacturers also produce a large number of discarded bricks. These bricks have no reasonable tre...
