Embodiment 1

[0013] Example 1: Use aluminum-containing sludge from waterworks to prepare non-fired bricks, which are prepared from the following raw materials in the following proportions: 74% of aluminum-containing sludge from waterworks after drying, 10% of cement, 0.5% of quicklime, and gelling agent 0.3%, accelerant 0.2%, sodium silicate 0.15%, and the particle size of aluminum-containing sludge from waterworks is ≤0.8mm. 0.15% chlorine salt series antifreeze has also been added to the mass ratio of each raw material, which is suitable for practical use in cold regions in winter. Its preparation method is as follows: 1. Mixing materials: mix the aluminum-containing sludge, cement, quicklime, gelling agent, accelerator and sodium silicate according to the above weight ratio after drying, add water and stir until uniformly mixed, and the water accounts for 14.7%; 2. Forming: send the mixed material into the cutting machine for cutting and forming; 3. Steam drying: send it into the steam ...

Embodiment 2

[0014] Example 2: Use aluminum-containing sludge from waterworks to prepare non-burning bricks, which are prepared from the following raw materials in the following proportions: 75% of aluminum-containing sludge from waterworks after drying, 15% of cement, 0.8% of quicklime, and gelling agent 0.5%, Accelerator 0.4%, Sodium Silicate 0.15%, wherein the particle size of aluminum-containing sludge from waterworks is ≤0.8mm. 0.15% chlorine salt series antifreeze has also been added to the mass ratio of each raw material, which is suitable for practical use in cold regions in winter. Its preparation method is with embodiment 1.

Abstract

The invention relates to baking-free brick made of aluminum sludge of water works and belongs to the technical field of environmental engineering. The baking-free brick comprises, by weight, 70%-80% of dried aluminum-containing sludge of the water works, 10%-15% of cement, 0.5-0.8% of quicklime, 0.3%-0.5% of gelling agent, 0.2%-0.4% of accelerating agent, 0.1%-0.15% of sodium silicate and 7%-15% of water. The baking-free brick made of the aluminum sludge of the water works has the advantages that waste difficult to treat is fully utilized and is turned into wealth, resources and energy are saved, environmental pollution is eliminated, the production cost is low, and the curing period of the baking-free brick is advanced by 1 / 3 day in comparison with the curing period of conventional baking-free brick.

Description

technical field [0001] The invention relates to a process for treating aluminum sludge from a waterworks, in particular to a technique for making unburned bricks by using the aluminum-containing sludge from a waterworks, and belongs to the technical field of environmental engineering. Background technique [0002] With the continuous advancement of my country's infrastructure construction, the demand for bricks as building envelope materials in infrastructure projects is also increasing. For a long time, the sintered bricks widely used in our country still use clay as the main raw material, which not only destroys the cultivated land, but also has high energy consumption, poor thermal insulation performance, and bulky bricks, which cannot reflect good advantages in actual engineering operations. . In recent years, with the in-depth implementation and implementation of the national policy of "no clay and limited stickiness", research on the preparation of new wall materials ...
