Embodiment 1

[0016] After the designed and measured mud cake, construction waste powder, coal cinder and admixture are uniformly stirred, they are aged for 48 hours, and the water content of the materials is controlled at 16% to 18%, and they are used for later use. The aged material is made into adobe, and the dimensions of the wet adobe are: length 250mm, width 118mm, height 92mm. Square hole, porosity 30%, after drying (using the heat released from the flue of the roasting kiln), the dimensions of the dry brick: length 242mm, width 116mm, thickness 91mm, moisture content less than 7%. Send it to the wheel kiln for roasting, and control the roasting temperature at 800°C to 1100°C to make new environmentally friendly bricks.

[0017] The finished bricks were tested for appearance and compressive strength, and the test results are shown in Tables 1-4.

[0018] Table 1 The weight ratio of each component in the trial mixing process of new environmentally friendly fired bricks (admixture 0) ...

Abstract

In the invention, ground building wastes and slurry and pressed mud cakes, serving as aggregates, are sintered by adding coal wastes and additives in proper quantity to obtain the novel environmental protection type clinker bricks which have high performance and can replace the clay bricks. Compared with the common clay clinker bricks, the clinker bricks of the invention are lower in production cost and higher in compressive strength. In the formula of the novel environmental protection type clinker bricks, all raw materials are from building and industrial wastes, so that the problem of treating waste building slurry and building wastes is solved, the problem of environmental pollution caused by solid wastes is also solved, the farming land resources are protected, and the cyclic utilization of solid wastes is realized.

Description

technical field [0001] The invention relates to an environmentally friendly sintered brick formula, in particular to a method suitable for the production of waste mud, construction waste and waste cinders produced in geotechnical engineering (such as survey drilling, cast-in-situ pile and anchoring engineering, trenchless construction, etc.) A sintered brick formula belongs to the technical field of civil engineering and building materials. Background technique [0002] Solid clay bricks are traditional wall materials, especially in China, where the use of solid clay bricks accounts for more than 70% of the total wall materials. However, mass production of solid clay bricks requires digging and destroying fields, consumes valuable land resources, and seriously damages the ecological balance. Over the years, relevant state ministries and commissions have repeatedly issued orders to prohibit the production and use of solid clay bricks in some cities across the country. There...
