Embodiment 1

[0014] Environmental protection and energy-saving non-burning bricks are prepared from the following raw materials in the following weight ratio: 78% tailings sand, 4% cement, 8% lime, 5% dedusting ash, and 5% large-grained sand with a particle size of 5-10mm.

[0015] Its preparation method is as follows:

[0016] 1. Mixing: mix tailings sand, cement, lime, dust and aggregate according to the above weight ratio, add water and stir until uniformly mixed, water accounts for 8-12% of the total weight; 2. Molding: mix the mixed material 3. Steam drying: sent to the steam drying room, controlled temperature 80-110 ℃, pressure 0.02-0.05MPa, steam drying 24 hours 4. Out of the room check.

Embodiment 2

[0018] Environmental protection and energy-saving non-burning bricks are prepared from the following raw materials in the following weight ratios: 75% of tailings sand, 4% of cement, 9% of lime, 7% of dedusting ash, and 5% of stones with a particle size of 5-10mm. Concrete preparation method is identical with embodiment 1.

Embodiment 3

[0020] Environmental protection and energy-saving non-burning bricks are prepared from the following raw materials in the following weight ratios: 70% tailings sand, 6% cement, 10% lime, 6% dedusting ash, and 8% large-grained sand with a particle size of 5-10mm. Concrete preparation method is identical with embodiment 1.

Abstract

The invention relates to the construction materials technical field, in particular to an environmental protective and energy saving burnt-free brick, which solves a problem of existing building used bricks that a large amount of land resources and coal resources are wasted. The environmental protective and energy saving burnt-free brick is made from the raw materials with the following weight portions of 60-78 portions of mine tailings, 4-8 portions of cement, 8-16 portions of white lime, 5-10 portions of precipitator dust and 5-10 portions of aggregate. The preparation method is as follows: firstly, materials mixing; secondly, forming; thirdly, steam drying; fourthly, categorizing. The invention uses waste mine tailings to produce building used bricks, which lowers the cost, avoids large amount of mine tailings from being packed and idled and occupying large amount of lands and reduces the destructions on the land resources at the same time. And through the steam drying which is similar to sintering directly with fire, a large amount of the coal resources can be saved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environment-friendly, energy-saving and burn-free brick. Background technique [0002] At present, the bricks used in construction are sintered bricks. The firing process of sintered bricks generally goes through several steps: digging soil and mud, stripping and drying, igniting the kiln, firing and cooling, and opening the kiln to produce bricks. Therefore, with the sharp increase in the use of building bricks in recent years, a large amount of farmland has been excavated and land resources have been seriously damaged; The firepower is kept at a suitable temperature, and the burning process can be completed by continuing to burn for eight or nine days. The whole process consumes a lot of coal. [0003] At the same time, when mineral deposits are mined all over the country, a large amount of waste - tailings sand will be produced, which can only be piled up and idled, occup...
