Problems solved by technology

For example, the existing gypsum blocks have problems such as high water absorption and low compressive strength, resulting in low single-point hanging performance and low masonry height, and cannot guarantee their firmness in the face of high-strength construction during building use. sex
In addition, the existing gypsum blocks have poor fire performance and short service life
It is clear that existing gypsum blocks cannot meet people's needs more effectively

Abstract

The invention relates to the field of building materials, and particularly relates to a high-density gypsum block. The high-density gypsum block is prepared from solid raw materials and water, wherein the weight ratio of the water to the solid raw materials is (2:5)-(3:5); and the solid raw materials comprise the following raw materials in parts by weight: 20-60 parts of alpha gypsum powder, 15-35 parts of beta gypsum powder, 10-55 parts of desulfurized gypsum powder, 1-20 parts of calcium carbonate, 1-20 parts of calcium hydroxide, 1-10 parts of slag powder, 1-10 parts of talcum powder, 1-10 parts of cement, 1-10 parts of basic sodium carbonate, 1-10 parts of water-reducing agent powder, 0.01-5 parts of glass fiber and 1-10 parts of defoaming agent powder. The gypsum block has high compression strength, high carrying capacity, favorable single-point suspension performance and low water absorptivity, can be used under the construction conditions of having high-intensity construction requirements, can realize a high building height under the condition of satisfying building requirements, and has high self stability, thereby more effectively satisfying requirements of people, and solving the existing problems in the prior art.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a high-density gypsum block. Background technique: [0002] Gypsum blocks are usually building gypsum products made of building gypsum powder as the main raw material, mixed with water, poured and dried. At present, the current domestic JC / T698-2010 industry standard system is the general standard for gypsum blocks in the construction industry. Under normal circumstances, in ordinary building construction, gypsum blocks can be used as wall pads, masonry block walls, for installing pipelines and pendants, etc. Compared with other building materials, gypsum blocks have the advantages of light weight, good seismic performance, good thermal insulation performance, dry operation, short construction period, superior comfort, good sound insulation performance, etc., and gypsum blocks are naturally free of harmful substances. No radiation, no discharge of three wastes during processi...
