Problems solved by technology

At present, ordinary Portland cement is mainly used in the preparation of foam concrete, but the setting time of ordinary Portland cement is relatively long. Although some coagulant products can shorten the setting time to less than 10 minutes, due to the slow development of its early strength , will still face the problem of low or even no strength in the later stage

Abstract

The invention discloses a lightweight foam concrete for decorative engineering, which comprises the following raw materials according to parts by weight: 20-40 parts of cement, 7-15 parts of phosphorus slag micropowder, 4-10 parts of diatom mud, calcium lignosulfonate powder 2~10 parts, silica powder 1~10 parts, fiber 6~10 parts, dispersible latex powder 3~9 parts, modifier 2~5 parts, foaming agent 1.5~3.5 parts. The invention provides a lightweight foamed concrete for decorative engineering and a preparation method thereof. The industrial solid waste phosphorus slag micropowder is mainly used as a cementitious material, and its potential activity is stimulated by calcium lignosulfonate powder and a modifier. The prepared concrete has the characteristics of fast hardening and early strength, which solves the problems of long setting time and easy collapse of ordinary Portland cement, short setting time, small deformation coefficient, low density and light weight, which is suitable for indoor and outdoor. For decoration, it has good social application value.

Description

technical field [0001] The invention belongs to the field of decoration engineering, and in particular relates to a lightweight foam concrete for decoration engineering and a preparation method thereof. Background technique [0002] Building energy-saving is the focus of energy-saving work in the world today. Since this century, my country has invested a lot of manpower and material resources in the research and development of new energy-saving building materials. Different from ordinary building materials, new environment-friendly and energy-saving building materials are not only required to have the characteristics of light weight and high strength, but also must have the advantages of heat preservation, heat insulation, sound insulation, fire prevention, moisture resistance, and earthquake resistance. In addition, new energy-saving building materials also require raw materials to use low-carbon emission materials or industrial waste residues as much as possible, and use n...
