Abstract
The invention relates to environment-friendly dry powder mortar, which comprises the following constituents in percentage by weight: natural sand 35-40%, oredressing debris 35-40%, Portland cement 10-30%, pulverized fuel ash 5-15%, and cellulose ether 0.15-1%. The various materials are mixed evenly according to proportions by weight and evenly stirred to obtain the dry powder mortar. By substituting the natural sand by dressing debris, the dry powder mortar not only has low cost, but also is economic and environment-friendly; cellulose ether is adopted, and therefore the water-retaining property of mortar is increased; and lignin is added, therefore the anti-cracking performance of mortar can be effectively increased.
Description
Technical field
The invention belongs to building material field, relate to mortar, especially a kind of environmental protection dry-mix.
Background technology
Dry-mix is wider in the building trade purposes, is divided into masonry mortar, motar, ground mortar etc.At present, dry-mix generally adopts natural sand as main component, and preparation has cement and additive etc., and cost is higher, and water-retentivity and ultimate compression strength are all general.
Correlation technique at present patent application; by retrieval; find one piece of patent publication us: a kind of dry powder mortar of mine tailings (CN101560083); it comprises following ratio of weight and number component: 40～60 parts in copper CHARACTERISTICS OF TAILINGS SAND or iron tailings sand; 20～30 parts in river sand; 10～30 parts of few clinker aggregate portland cements; 0.5～1.5 part of water-retaining admixture; be applicable to and build by laying bricks or stones; plaster; ground and common waterproofing work; utilize cement with little clinker to replace traditional ordinary Portland cement; partly replace river sand with CHARACTERISTICS OF TAILINGS SAND; reduced the consumption of emission of carbon-dioxide and river sand resource; realized slag; slag; ecotope has been protected in recycling of solid wastes utilizations such as mine tailing.
Above-mentioned open source literature and present patent application are close, but material constitutes difference, and ultimate compression strength is lower.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of with low cost, environmental protection, good water-retaining property, environmental protection dry-mix that ultimate compression strength is high are provided.
The object of the present invention is achieved like this:
A kind of environmental protection dry-mix, it constitutes component and weight percentage ranges is respectively:
Above-mentioned various materials are mixed according to weight proportion, get final product after stirring.
And, also adding xylogen, its weight percent is the 1-2% of material gross weight.
And the model that described ether of cellulose adopts is HPMC.
Advantage of the present invention and positively effect are:
1, trunk flour sand slurry adopts the ore dressing chip to substitute natural sand, has not only reduced cost, also economic environmental protection.
2, trunk flour sand slurry adopts ether of cellulose, has improved the water-retentivity of mortar.
3, trunk flour sand slurry adds xylogen, can effectively improve the resistance to cleavage of mortar.
