Embodiment 1

[0034] Hollow glass microsphere foam concrete, its components are:

[0035] Raw material mass g

[0036] (1) Cementitious material

[0037] Rapid hardening sulfoaluminate cement 850~950

[0038] (2) Additives

[0039] Hollow glass microspheres 50~150

[0040] (3) Water 550~650

[0041] (4) Foam: the volume (ml) accounts for 12.5 to 17.5 times the cement volume, and its preparation process is:

[0042] 1. Selection of raw materials: The fast-hardening sulfoaluminate cement is 42.5R fast sulfoaluminate cement produced by Tangshan Jidong Cement Co., Ltd.; the hollow glass microspheres are jointly developed by Sinosteel Maanshan Mining Research Institute and the Chinese Academy of Sciences H46 type, the main component is soda lime-borosilicate; the foaming agent is FC composite foaming agent produced by South Korea Xinyu Machinery Co., Ltd.;

[0043] 2. Pour the fast-hardening sulfoaluminate cement into the mixing pot and stir slightly (low speed to make the material unif...

Abstract

The invention provides a foam concrete insulation material which is prepared by blending hollow glass bead partially-replaced cement and foaming agent and a preparation method of the foam concrete insulation material. The insulation material comprises components, by weight, of 5%-15% of hollow glass bead partially-replaced cement and foaming agent with 1000g of rapid hardening sulphoaluminate cement as a standard, the water-binder ratio is 0.55-0.65, and the volume of foam mixing amount is 12.5-17.5 times of the volume of cement. In a preparation process, a neat paste blender is used for evenly blending cement slurry, then hollow glass beads are gradually added, half of residual mass of the hollow glass beads is added, foams are added after slow and even blending, and molding is carried out. The hollow glass beads have the advantages of light weight, high compression strength, low thermal coefficient, good flowability and the like, and compression strength and balance performance of the prepared foam concrete can be guaranteed under a precondition that the dry density is lower than 190kg / m3.

Description

technical field [0001] The invention relates to a lightweight building wall material, in particular to a preparation method for a lightweight high-strength foam concrete wall material with good thermal insulation and fireproof performance. Background technique [0002] Building wall materials must not only have the effect of building energy saving, but also have excellent fire and flame retardant properties. At present, most of the building exterior wall insulation materials used in the market are organic materials such as benzene boards, but because this material is flammable and easily Due to aging and poor durability, fire accidents have occurred frequently in thermal insulation construction projects in various places. The benzene board will melt quickly in the event of a fire. The smoke is large and the toxicity is high. Without solving the fire safety problem of wall insulation materials, my country's building energy-saving projects will have major fire hazards, which...
