Abstract

The invention relates to special masonry mortar for an insulating building block, and belongs to the building materials. The mortar is prepared from the following materials in parts by weight: 150-300 parts of cement, 70-120 parts of ground calcium carbonate, 10-25 parts of an additive and 580-750 parts of basalt. The special masonry mortar for the insulating building block is reasonable in proportion, has good inpeaceability, water-retaining property and binding strength. The special insulating building block for carrying out bricking on non-bearing and bearing insulating walls approximate to light bricks in dry shrinkage deformation and heat conduction has great meaning, and is wide in market prospect, and remarkable in economical and social benefits.

Description

The insulation blocks special masonry mortar
Technical field
The invention belongs to material of construction, particularly relate to a kind of insulation blocks special masonry mortar.
Background technology
At present country advocating energetically development energy-conservation, save land, sharp useless heat insulating novel exterior wall enclosure system, various non-bearings, load-bearing light heat insulation blocks demand get more and more, all build lightweight wall block by laying bricks or stones with common masonry mortar at present, common masonry mortar is generally sand-cement slurry or mixed mortar, and the performance density of this class mortar is generally 1600~1800kg/m 3, thermal conductivity is 0.18~110W/ (mlK), and the apparent density of light heat insulation blocks is generally 450~950kg/m 3Thermal conductivity is 0.115W~0.35W/ (mlK), because both thermal conductivity gaps are larger, cause whole masonry to have " cold bridge " phenomenon, reach about 25% by building the power loss that mortar joint causes by laying bricks or stones, produced heat bridge aspect the mortar joint building by laying bricks or stones, even dewfall appears in whole metope, and the long echinid accumulation of salt in the surface soil makes the mouldy phenomenon of body of wall, and living environment is exerted an influence, though through clearing up and whitewashing processing, all of no avail.Because what all adopt at present is the external wall outer insulation way; in case exterior wall produces the crack rainwater and can enter along the crack in the body of wall and be difficult for evaporation; particularly exterior wall has benzene plate protection, so in case rainwater enters indoor wall produces the long echinid phenomenon of the accumulation of salt in the surface soil and will forever can not solve.Between the two the coefficient of shrinkage differs also a lot of in addition, causes common masonry mortar and light block bonding undesirable, and whole masonry is affected the intensity of masonry in the drying and watering cycle process.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and a kind of insulation blocks special masonry mortar is provided, and has good physical and mechanical property, thermal property and weather resistance.
Insulation blocks special masonry mortar of the present invention, be by following material by weight proportioning make: 150~300 parts of cement, 70~120 parts of coarse whitings, 10~25 parts of admixtures, 580~750 parts in basalt.
Optimum ratio of the present invention is: 200~280 parts of cement, 90~110 parts of coarse whitings, 12~20 parts of admixtures, 600~700 parts in basalt.
Insulation blocks special masonry mortar of the present invention, reasonable ratio, it has good workability, water-retentivity and cohesive strength, is close with light block on dry-shrinkage deformed, heat conductivility, and is good with the light block bond effect, do not ftracture, high insulating effect, energy-saving low-carbon is applied to non-bearing and the load bearing heat preserving body of wall special-purpose heat-insulation masonry sand of laying bricks significant, market outlook are extensive, and economic benefit and social benefit are remarkable.In addition, dry powder prefabricated thermal insulation mortar is compared with the mortar of the on-the-spot preparation of traditional technology, and many advantages are arranged.At first be that quality product is high, construction site is difficult to get all the ready desired all raw materials, and on-the-spot preparation of construction also can't guarantee strictly to prepare by the accurate weighing of prescription requirement, and the mortar mass discrepancy is very large, can't guarantee to satisfy specification of quality; Next is that production efficiency is high, adopts the premixing dry-mix, greatly improves the speed of building operation, improves the whole modernization level of construction industry; Moreover be little to the pollution of environment, be convenient to civilized construction.The quantitative package of dry mash is convenient to transportation and is deposited, and unit in charge of construction can quantitatively purchase as required, has not only saved raw material but also made things convenient for construction management.
