Energy-saving insulating brick

Abstract

The invention relates to an energy saving heat preserving brick which solves the technical problems that the prior construction wall has cockamamie energy saving and heat preserving measure constructions, long construction period and high cost. The invention comprises the steps as follows: mixing and stirring the raw materials, extruding for shaping and maintaining. The weight ratio of the raw materials is that: 230 to 320 parts of portland cement, 35 to 20 parts of swelling perlite, 430 to 610 parts of general sand, 70 to 15 parts of cinder, 6 to 3 parts of straw, 4 to 2 parts of plant ash, 1.6 to 2 parts of felted wool fibre, and 97 to 135 parts of water. The invention has good energy saving and heat preserving capacities and good compression resisting intensity.

Description

Technical field

[0001] The present invention relates to bricks or blocks of buildings, in particular to thermal insulation bricks or blocks of buildings. Background technique

[0002] The existing energy-saving building wall adopts energy-saving insulation measures to apply a certain thickness of insulation mortar or external insulation board to the outer wall of ordinary masonry. Ordinary masonry generally uses solid clay bricks, hollow bricks, aerated concrete blocks and ceramics. It is made of granular concrete hollow blocks. The above-mentioned energy-saving and thermal insulation methods are cumbersome in construction, long in construction period, high in cost, and the walls are easy to crack and leak, which seriously affect the insulation effect of buildings. Summary of the invention

[0003] Aiming at the technical problems of cumbersome construction, long construction period, and high cost of the above-mentioned energy-saving insulation measures, the present invention pr...
