Embodiment 1

[0018] After the designed and measured mud cake, construction waste powder, fly ash and admixture are uniformly stirred, they are aged for 48 hours and set aside. The aged material is made into adobe, and the dimensions of the wet adobe are: length 250mm, width 120mm, height 94mm. After drying (using the heat released from the flue of the roasting kiln), the overall dimensions of the dry adobe brick are: length 242mm, width 118mm, height 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 fly ash garbage sintered bricks.

[0019] The finished bricks were tested for thermal conductivity and compressive strength, and the test results are shown in Tables 1-4.

Abstract

The invention provides a formula of high-performance, low-price fly ash waste baked bricks which can be used in actual production. The formula of the baked bricks, which uses waste slurry, construction wastes, fly ash and other solid wastes as raw materials, solves the problem of environmental pollution caused by the solid wastes, protects farmland resources and realizes the recycling of the solid wastes.

Description

technical field [0001] The invention relates to a method for sintering fly ash garbage bricks, in particular to a waste mud suitable for power plant fly ash and geotechnical engineering (such as survey drilling, cast-in-situ pile and anchoring engineering, non-excavation construction, etc.) The invention discloses a formula for making sintered bricks from pressed mud cake and construction waste, belonging 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 c...
