Embodiment Construction

[0013] The following examples describe the present invention in more detail:

[0014] According to the weight ratio of 68-70% of waste rock powder, 28-30% of cement, 1-2% of LZ981-2 reinforcing agent and 0.1-0.2% of rare earth, mix the raw materials evenly, add water to adjust evenly, place in the mold, add Press for 3 seconds or vibrate for 4 minutes to make a product. The rare earths mentioned therein are 45% greening rare earths produced by Baotou State-run 202 Factory; LZ981-2 enhancer produced by Hong Kong Chemical Factory.

[0015] According to the weight ratio of 70% of waste rock powder, 28% of cement, 1.9% of LZ981-2 reinforcing agent and 0.1% of rare earth, mix the raw materials evenly, add water to mix evenly, place in the mold, pressurize for 3 seconds or vibrate for 4 minutes , 20 days of health preservation to make products. The rare earths mentioned therein are 45% greening rare earths produced by Baotou State-run 202 Factory; LZ981-2 enhancer produced by Ho...

Abstract

The invention provides a mullock powder energy-saving hollow building brick and the making method thereof, uniformly mixing mullock powder 68-70wt%, cement 28-30wt%, LZ981-2 intensifier 1-2wt% and rare earth 0.1-0.2wt%, adding in water and blending uniformly, placing mixture in a mould, pressurizing for 3 seconds or vibrating for 4 minutes, and curing for 20 days to make the finished product which has high intensity, energy saving and thermal insulation properties. And the invention is beneficial to protect country resources.

Description

(1) Technical field [0001] The invention relates to a building material, in particular to a building material produced from waste raw materials. The invention also relates to a method of making this building material. (2) Background technology [0002] Traditional clay sintered bricks and clay sintered hollow bricks not only need to erode a large amount of arable land for their production, but also consume a lot of energy. Therefore, in recent years, the country has begun to restrict the production and application of this traditional building material. The strength of ceramsite / fly ash hollow brick is too low, and the application range is limited to a certain extent. From another point of view, the waste rock and waste rock powder produced in the production process of quarries and mines occupy and erode land resources such as cultivated land in large quantities due to accumulation, and even cause environmental pollution. (3) Contents of the invention [0003] The object...
