Abstract

The invention belongs to the field of building materials and particularly relates to a molybdenum tailing aerated concrete block and a manufacturing method thereof. The molybdenum tailing aerated concrete block comprises, by weight, 65-78% of molybdenum tailings, 12-18% of quick lime, 5-18% of cement, 2.92-4.91% of gypsum and 0.08-0.09% of aluminum paste. The manufacturing method includes the following steps of (1) pre-processing raw materials; (b) crushing and grinding the quick lime to obtain quick lime powder; (c) preparing 8-10% aluminum paste suspension liquid by using the aluminum paste; (2) dosing and pouring; (3) precuring; (4) demolding and cutting; (5) steaming. The molybdenum tailing aerated concrete block is light in texture and good in thermal insulation property, has high compressive strength, overcomes the defect that a powder ash aerated concrete block is low in compressive strength, can replace clay bricks completely and is wide in use range. The method is simple in process and low in product energy consumption.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a molybdenum tailings aerated concrete block and a preparation method thereof. Background technique [0002] With the improvement of resource and environmental protection awareness, traditional building materials have become less and less able to meet the needs of society in exchange for unsustainable development at the cost of a large amount of resource consumption and serious damage to the ecological environment. According to incomplete statistics, 70% of the building materials in my country are wall materials. Due to the use of traditional wall materials The most resources are clay, limestone and sandstone, which seriously consume land and mine resources and cannot be recovered. Furthermore, block concrete made of traditional concrete materials has a large proportion, and the utilization rate of raw materials is not high, which greatly increases the construction cos...
