Abstract

Belonging to the technical field of building materials, the invention discloses a self-thermal insulation building block and a preparation method thereof. The self-thermal insulation building block comprises the following raw materials by mass: 400-450 parts of cement, 25-80 parts of neutral zirconium-containing silica residue, 1-140 parts of quartz sand silt, 1-2 parts of calcium stearate, 4-10 parts of a water reducing agent and 1-2 parts of polypropylene fiber. The self-thermal insulation building block provided by the invention has the advantages of no secondary by-product, waste utilization and environmental protection, no need of autoclaved curing, fast strength development, short production cycle, substantial reduction of production cost, and further slow increase of later strength without decline. Thus, the product has good long-term mechanical properties, also the building block water absorption rate is less than 18%, and the frost resistance and durability are good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a self-insulating block and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy and the continuous increase of population, resource consumption and environmental pollution are intensifying, and the constraints on economic and technological development have become increasingly prominent, which has become an important issue restricting the development of our national economy. Energy saving and emission reduction has gradually become a consensus. With our country's emphasis on building energy conservation and the implementation of policies related to building energy conservation, building thermal insulation and energy-saving materials have been rapidly developed and utilized. Foamed concrete has long service life, non-toxic, light weight (200-800kg / m 3 ), excellent thermal performance, sound absorption and soun...
