Problems solved by technology

[0002] In the prior art, the production of aerated concrete is generally made of cement, lime, sand or fly ash, gypsum, aluminum powder, etc. The general strength of aerated concrete is lower than 5Mpa, and the strength of aerated concrete sold on the market is mostly less than 3.5Mpa
Moreover, air-entrained concrete has strong water absorption and insufficient hanging force, which seriously restricts the use of new wall materials for exterior walls.

Abstract

The invention discloses a novel haydite concrete light-weight building block walling material and a preparation method thereof. The walling material is prepared from a cementing material, haydite, boiler slag, water and silica sand powder. The preparation method comprises the following steps: drying building sand of which the content of silicon dioxide is greater than 90%, or crushed quartzite, and grinding to obtain silica sand powder of which the specific area is 400-500m<2> / kg; weighing 0.11-0.43 part of silica sand powder, 1 part of cementing material, 1-2.6 parts of tailings, 1.3-3.4 parts of haydite, 1.5-3.5 parts of boiler slag, 0.30-0.50 part of water and 0.0021-0.0050 part of foaming agent; adding the silica sand powder, cementing material, tailings, haydite, boiler slag and water into a forced mixer, evenly mixing, quickly adding the foaming agent, and mixing for 30 seconds; and evenly filling the mixture in a die, carrying out extrusion forming, carrying out natural curing or atmospheric steam curing, and curing at 175-190 DEG C under high pressure for 2-6 hours, thereby obtaining the walling material.

Description

technical field [0001] The invention relates to a novel wall material of ceramsite concrete lightweight blocks, and also relates to a method for preparing the novel wall material of ceramsite concrete lightweight blocks. Background technique [0002] In the prior art, the production of aerated concrete is generally made of cement, lime, sand or fly ash, gypsum, aluminum powder, etc. The general strength of aerated concrete is lower than 5Mpa, and the strength of aerated concrete sold on the market is mostly lower than 3.5Mpa. And aerated concrete has strong water absorption and insufficient hanging force, which seriously restricts the use of new wall materials for exterior walls. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a kind of industrial waste slag that can make full use of, the production cost is relatively low, and has light bulk density, high strength, low thermal conductivit...
