Abstract
The invention relates to thickening powder for preparing dry-mixed masonry mortar, which belongs to the thickening powder of building auxiliary materials. The thickening powder is formed by organic materials, and comprises the following components by weight percentage: 15-16 percent of hydroxypropyl methyl cellulose ether, 75-77 percent of calcium lignosulphonate and 8-9 percent of starch ether. The thickening powder is used as an additive of the dry-mixed masonry mortar, which can obviously improve the workability, water retention property, mechanical property and durability of the dry-mixed masonry mortar. The invention has the advantages that the thickening powder is formed by organic materials, less in using amount, low in cost and suitable for industrialized production of the dry-mixed masonry mortar, has high requirement on quality control and no pollution, can obviously improve the workability, water retention property, mechanical property and durability of the dry-mixed masonry mortar, is convenient to store and convenient and rapid to use, has no radioactivity and corrosivity, reforms the preparation mode for building mortar in the prior art, eliminates the lime pool and the stirring mill built on the construction site, reduces dust raising and noises, realizes civilized construction, and produces favorable social and economic benefits.
Description
Technical field
The present invention relates to a kind of densification powder of building subsidiary material, especially a kind of densification powder for the preparation of dry-mixed masonry mortar.
Background technology
Dry-mixed mortar is the development trend of building operation, and the key of development dry-mixed mortar is exactly the development of densification powder.The dry-mixed mortar densification powder of current production has only been considered some performances of dry-mixed mortar on the one hand, such as water conservation or denseness etc., does not have comprehensive application property, mechanical property, the weather resistance of comprehensively considering dry-mixed mortar.Better still cost is higher for some dry-mixed mortar densification powder Performance Ratio on the other hand, and cost is high, and quality differs, common the building by laying bricks or stones and the motar Difficulty of having a large capacity and a wide range.
Summary of the invention
Technical problem: the objective of the invention is to provide a kind of densification powder for the preparation of dry-mixed masonry mortar, solve the higher problem of densification powder cost of making at present.
Technical scheme: the object of the present invention is achieved like this: this densification powder comprises hydroxypropyl methyl cellulose ether, wooden calcium and starch ethers; Described hydroxypropyl methyl cellulose ether is 15% ~ 16%, and wooden calcium is 75% ~ 77%, and starch ethers is 8% ~ 9%, is weight percentage.
The add-on of described densification powder in dry-mixed masonry mortar is 0.12% ~ 0.14% of mortar gross weight; Mortar is the mixture of cement, sand and flyash.
Described hydroxypropyl methyl cellulose ether viscosity is 100000mPas.
Beneficial effect: owing to adopted such scheme, improved the water-retentivity of dry-mixed masonry mortar, satisfied national regulation and Jiangsu Local rules, improved the denseness of mortar, improved the workability of mortar; Simultaneously mechanical property and the endurance quality of dry-mixed masonry mortar are all made moderate progress.Use this densification powder preparation M10 dry-mixed masonry mortar, the fundamental property of the dry-mixed masonry mortar of preparation: water consumption is 18%, and water retention is 90.0%, and denseness is about 80mm, and be 5.5h time of coagulation, and 28d ultimate compression strength is 12.3MPa, all satisfies standard.Selected material price is cheap, has solved the higher problem of present manufacturing densification powder cost, has reached purpose of the present invention.
Advantage: be comprised of organic materials, consumption is few, and quality control requirement is high, and price is low, pollution-free.Be applicable to the batch production production of dry-mixed masonry mortar.Can obviously improve workability, water-retentivity, mechanical property and the endurance quality of dry-mixed masonry mortar.This kind densification powder is stored convenient, easy to use, "dead" and corrodibility, reformed the preparation mode of the building mortar of prior art, Calcified pond and the stirrer that build by laying bricks or stones the working-yard have been cancelled, airborne dust and noise have been reduced, realize civilized construction, produced good Social benefit and economic benefit.
