Embodiment 1

[0011] Embodiment 1: A kind of vitrified microbead thermal insulation concrete, its component and weight ratio (kg / m 3 )for:

[0012] Vitrified beads: cement: sand: gravel: water: external admixture = 10:500:560:1150:170:0.5.

[0013] The production method is as follows: first put the sand, gravel, cement, water and external admixtures in the above ratio into the mixer, and after stirring for 0.5 minutes, then put the vitrified microbeads in the above ratio into the mixer evenly, and after stirring for 1-2 minutes, That's it.

Embodiment 2

[0014] Embodiment 2: A kind of vitrified microbead thermal insulation concrete, its component and weight ratio (kg / m 3 )for:

[0015] Vitrified beads: cement: sand: gravel: water: external admixture = 30:320:460:1400:230:2.

[0016] The production method is as follows: first put the sand, gravel, cement, water and external admixtures in the above ratio into the mixer, and after stirring for 0.5 minutes, then put the vitrified microbeads in the above ratio into the mixer evenly, and after stirring for 1-2 minutes, That's it.

Embodiment 3

[0017] Embodiment 3: A kind of vitrified microbead thermal insulation concrete, its component and weight ratio (kg / m 3 )for:

[0018] Vitrified beads: cement: sand: gravel: water: external admixture = 20: 410: 500: 1250: 200: 1.25.

[0019] The production method is as follows: first put the sand, gravel, cement, water and external admixtures in the above ratio into the mixer, and after stirring for 0.5 minutes, then put the vitrified microbeads in the above ratio into the mixer evenly, and after stirring for 1-2 minutes, That's it.

Abstract

The invention relates to a concrete, especially a concrete with good thermal insulation property, concretely a vitrified microball thermal insulation concrete comprising: vitrified microballs, cement, sands, stones, water and external doping. And it is applied to enclosure structures of buildings, able to meet intensity requirements for structural components and largely reduce energy consumption of buildings, according with building energy-saving requirements in our country; besides, all the used materials are inorganic matter, having stable physical-chemical properties, non-toxic and harmless, and able to meet environmental protection requirements.

Description

technical field [0001] The invention relates to concrete, in particular to concrete with good thermal insulation performance, in particular vitrified microbead thermal insulation concrete. Background technique [0002] At present, more than 90% of the multi-high-rise buildings at home and abroad are reinforced concrete structures; a small number of steel structure buildings, their enclosure structures including outer walls and floor (roof) covers are also mainly made of concrete materials. In today's comprehensive "brick ban", concrete structures are more widely used, but concrete is the main material of the building, and its thermal insulation performance is very poor (its thermal insulation coefficient is about 1.7w / m.k). Therefore, in order to ensure the temperature inside the building Therefore, it is necessary to add an insulation layer to the inner and / or outer layers of the concrete structure. Compared with the insulation materials used in the inner and outer insulati...
