Abstract

The invention discloses a high-strength lightweight building material and a preparation method thereof. The high-strength lightweight building material is prepared from the following components in parts by weight: 10-30wt% of coal ash, 1-4wt% of an expanding agent, 5-15wt% of acetylene sludge, 6-10wt% of a reinforcing agent, 20-50wt% of quartz powder and 20-50wt% of aluminate cement. The preparation method comprises the steps of pretearting the raw materials and sintering under certain conditions to obtain the high-strength lightweight building material. The obtained building material is low in density and high in strength and conforms to the requirements of modern building materials; in addition, the purposes of energy consumption and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a high-strength lightweight building material and a preparation method thereof. Background technique [0002] Traditional building concrete is made of cement as cementing material, sand and stone as aggregate, and mixed with water in a certain proportion. Although it has the advantages of high strength and good durability, most of them have problems such as large weight, high water absorption, high thermal conductivity, and low strength, which make the building bear heavy loads, poor thermal insulation and earthquake resistance, and some consume a lot of energy. Natural resources such as clay do not meet the performance requirements of modern building materials for high strength, shock resistance, heat preservation, fire prevention, sound insulation, and energy saving, and their application range is limited. [0003] Lightweight building materials have the ...
