Burning-free and steam curing-free brick and preparation method thereof

Abstract

The invention relates to the technical field of building materials and in particular relates to a burning-free and steam curing-free brick and a preparation method thereof. The burning-free and steamcuring-free brick comprises a body, and is characterized in that the right side of the body is fixedly connected with a crushing box; the right side of the crushing box is fixedly connected with a fixing shaft; the right side of the fixing shaft is fixedly connected with a threaded rod; a crushing port is formed in the top of the crushing box; a crushing groove is formed in the bottom of the crushing box; rotating shafts are symmetrically and fixedly arranged on the left and right sides of inner walls of the crushing box; a crushing roller is fixedly connected between the rotating shafts; regulating valves are symmetrically arranged on the crushing box and positioned on the fixing shaft; a discharging hole is formed in the bottom of the crushing box; a feeding hole of a proportioning cavity is formed just under the feeding hole; and a stirring device is arranged inside the proportioning cavity. According to match of the crushing box, the crushing roller and a filter box, the mixing effect of ingredients is excellent by virtue of the stirring device, the using effect is enhanced after proportioning, the brick quality is improved, the using effect is excellent, and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a non-burning and non-steaming brick and a preparation method thereof. Background technique [0002] Yue Yunlong and others used red mud and fly ash as raw materials and cement as curing agent to make unburned bricks. The ingredients were: 60% alkali slag cement, 30% red mud, and 10% fly ash, which were produced by pressure molding. The mechanical properties of the unfired bricks obtained meet the national standards for fly ash bricks. Wang Mei et al. developed red mud fly ash bricks, and the best ratio in the test was: red mud 25-40%, fly ash 18-28%, aggregate 30-35%, cement 1%, lime 8- 10%, gypsum 2-3%, water content 15-17%, aging 8-12h, using 40MPa pressure molding, the mechanical properties of the unburned bricks produced meet the requirements of the national standard for autoclaved lime-sand bricks MU15 . Shenglei and others have done some research on red mud c...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the above-mentioned technical solution for making bricks from red mud has the following disadvantages: ①The molding pressure is high or aggregates are added, so the brick has a large volume, which does not meet the requirements of light weight and high strength; ②The required moisture content is low, High requirements on the molding process, if the production control is not good, it is easy to make the water stability and atmospheric stability of unburned bricks poor; ③The use of cement and other raw materials will inevitably increase the production cost of unfired bricks, and will also affect the promotion of this technology
