Abstract
The present invention discloses light heat insulating mortar which is characterized in that the mortar is composed by the mixing of 10 to 50 wt% of diatomite, 15 to 35 wt% of pearlite, 10 to 25 wt% of cement, 5 to 15 wt% of silica gel powder and 10 to 50 wt% of fly ash. The present invention has the advantages of light weight, thermal insulation, heat insulation, simple construction, high speed and smooth wall surface after brushing, and the mortar of the present invention can be used as an inner insulating heat preservation material of outer walls.
Description
The present invention relates to a kind of mortar for building, particularly a kind of light heat insulating mortar.
Along with the development of novel material, new technology, material of construction forward lightweight, insulation, heat insulation direction develop, and large quantities of energy-saving building technologies and energy saving building product innovation, novel material have occurred.Single with regard to thermal insulation mortar, cement mo(u)ld, gypsum model, Shuanghui powder type swelling perlite heat-insulating mortar are just arranged, and compound insulating material such as insulating rare earth composite material, sepiolite, expansion little molehill stone etc., but these materials all do not have light weight, insulation and heat insulation advantage simultaneously.Along with diatomaceous development and use, diatomite self institute inherent porousness, light weight are familiar with by building field more and more.At present, diatomite is applied on Industrial buildings as heat preserving and insulating material, and mainly contains two kinds of purposes: one, be the outer insulation that is used for the heat insulation and Thermal Equipment of Industrial Stoves furnace lining; Two, be diatomite powdery thing to be used for unsetting lagging material or to make admixture, additive of other lagging material etc.
The purpose of this invention is to provide a kind of light heat insulating mortar with light weight, insulation, insulative properties.
The object of the present invention is achieved like this: a kind of light heat insulating mortar is characterized in that it is to be mixed by the diatomite of 10-50% (weight), the perlite of 15-35% (weight), the cement of 10-25% (weight), the silica-gel powder of 5-15% (weight) and the flyash of 10-50% (weight).Component that the present invention determines and proportioning are that repeatedly research trial gets, and wherein diatomite is China's reserves rich in natural resources, and its multiple hole, quality are light, select for use diatomite can fall the weight of light weight sand slurry greatly, increase insulation, the effect of heat insulation of mortar, simultaneously, it also has cohesive action.Select for use perlite as mortar aggregate, strengthen mortar strength.Silica-gel powder plays bonding and enhancement.Flyash is industrial residue, and it is the behave of turning waste into wealth that flyash is used for mortar, both can be it as applying filler in mortar, make it to bring benefit to the people, can solve industrial waste again and handle problems.Detect through Jiangsu Province's construction engineering quality inspection center, the basic mechanical design feature index of light heat insulating mortar is as follows:
Dry density≤500Kg/m
3Thermal conductivity≤0.085w/m.k
Ultimate compression strength 〉=2.5Mpa cohesive strength 〉=0.8Mpa
The fire resistance non-fire material
This light heat insulating mortar is carried out a small amount of as outer wall inner insulation material at two places whitewash test, test-results is:
| Test site | Metope area (m 2) | Whitewash thickness (mm) | Dry mash consumption (kg) | Stir water cement ratio | Speed of application | Dry back metope is apparent | Every m 2Wall plaster material cost unit/m 2 |
| Field one | 250 | 15 | 2500 | 1∶0.8 | Improve 1.5 times than ordinary mortar | There are not phenomenons such as the drum that ftractures, shelled | 7 |
| Field two | 120 | 20 | 1500 | 1∶0.8 | The same | The same | 8.75 |
From two test-results, usefulness light heat insulating mortar easy construction, speed are soon, afterwards the wall surface levelling cost is low in construction.
The present invention compared with prior art, its remarkable advantage is: one, unit weight is light, thermal and insulating performance good; Two, easy construction, fast, the construction back wall surface levelling of speed; Three, make full use of industrial residue, bigger social effect and economic benefit are arranged.Mortar of the present invention can be widely used as outer wall inner insulation material.
The invention will be further described below in conjunction with embodiment:
The light heat insulating mortar that embodiment 1. the present invention make, component of selecting for use and proportioning (weight %) are respectively:
(1) 10% diatomite fecula, appearance are canescence, bulk density≤0.7Kg/m
3, diatom test content is
60-85％；
(2) 15% pearlstone, unit weight are 80-150Kg/m
3, normal temperature thermal conductivity＜0.05-0.06
w/m.k；
(3) 25% 425 cement;
(4) 10% silica-gel powder;
(5) 40% flyash, the flyash radioactivity meets national standard.
And fineness of pulverized-coal ash, loss on ignition, water requirementization, sulphur trioxide, water ratio etc. meet flyash utilisation technology rules in concrete and mortar.
Get final product after the starting material of said components and proportioning are mixed.
Embodiment 2; Adjust set of dispense such as following according to embodiment 1:
(1) 50% diatomite;
(2) 20% perlite;
(3) 10% cement;
(4) 5% silica-gel powder;
(5) 15% flyash.
Embodiment 3: adjust set of dispense such as following according to embodiment 1:
(1) 25% diatomite;
(2) 35% perlite;
(3) 15% cement;
(4) 15% silica-gel powder;
(5) 10% flyash.
Embodiment 4: adjust set of dispense such as following according to embodiment 1:
(1) 20% diatomite;
(2) 10% perlite;
(3) 10% cement;
(4) 10% silica-gel powder;
(5) 50% flyash.
