Abstract
The invention discloses a mortar specially used for fly ash steam-pressing brisk construction. The special mortar comprises following raw materials, by weight, 1350 to 1550kg of natural sand, 183 to 337kg of cement, 32 to 60kg of fly ash, 2.15 to 7.15kg of an additive specially used for the mortar which is specially used for fly ash steam-pressing brisk construction, and 215 to 250kg of water. The preparation method comprises following steps: (1) natural sand, cement, fly ash, the additive and water are uniformly mixed via mechanical mixing according to the weight ratio; and (2) the mortar obtained in step (1) is subjected to mechanical stirring for 3min. The preparation method is simple; water consumption of common masonry mortar is reduced; workability is improved; compactibility is increased; later phase strength increasing is rapid, and water penetration resistance, frost resistance and durability are all improved. The surfaces of fly ash steam-pressing bricks are smooth, and bonding of the fly ash steam-pressing bricks with mortar is difficult. A certain proportion of fly ash and the additive are added into the mortar, so that performances of the mortar are improved effectively, cost is reduced, and binding power of the mortar with the fly ash steam-pressing bricks is increased.
Description
Technical field
The invention belongs to building material field, be specifically related to coal ash autoclaved brick masonry dedicated mortar and preparation method.
Background technology
Along with social progress, the needs in city, common brick is progressively got and is replaced, instead autoclaved fly ash brick and many novel wall material masonries have started to flow to market, and the mortar of Site and general ordinary mortar can not meet the demand of the novel wall material masonries such as autoclaved fly ash brick.
Also office's cement sand of adding some points again of adding some points is now just passable to the understanding of mortar for a lot of workmens, also needs to understand in depth raw-material performance when we develop mortar in fact.For example, cement is the powder of grey in others' eye, and in research staff's eye, should be the mixture of tricalcium silicate, Dicalcium Phosphate (Feed Grade), tricalcium aluminate, iron tricalcium aluminate, gypsum and filler, we are not at simple and mud, and we are not simple craftsman.Mortar field, is a field of not fully realized, and a lot of reaction mechanisms, due to too complicated, does not also have studied.Premixing mortar belongs to the field of polymer cement mortar, and polymkeric substance and cement interact and formed final cured body, and wherein deep mechanism, also needs to drop into a large amount of energy and go research.
The mortar of on-the-spot mixing, proportioning is unstable, seriously polluted is the large drawback of masonry project insoluble always, becomes the principal element of the on-the-spot mixing mortar effect of impact.And the application of premixing mortar has exactly solved this problem.In recent years, along with the mass-producing that premixing mortar is produced, the further reduction of production cost, added its steady quality, improved the advantage of work efficiency and civilized environmental protection, was applied to more and more widely masonry project.Premixing mortar because admixture flyash and admixture, and masonry mortar joint is reduced to 3-5mm, thereby greatly reduces the cold bridge effect of mortar joint, effectively improved the energy-saving effect of body of wall.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coal ash autoclaved brick masonry dedicated mortar and preparation method, this mortar is by cement, sand, flyash, coal ash autoclaved brick masonry dedicated mortar admixture and water are made, with flyash, replace in proportion cement consumption, reduce costs, reduce the water consumption of masonry mortar, improve workability, improve density, improve later strength and increase, improve to resist and mix anti-freezing property and endurance quality and reduce cost, with admixture, improve it and newly mix performance and impervious freeze proof cracking resistance, and improve the performance of concrete strength.
Technical scheme of the present invention:
A coal ash autoclaved brick masonry dedicated mortar, its composition of raw materials is: natural sand 1350～1550 Kg; Cement 183～337Kg; Flyash 32～60Kg; Coal ash autoclaved brick masonry dedicated mortar admixture (KDH-L type) 2.15～7.15kg; Water 215～250 Kg(make slurry consistency reach the water consumption of 70～90mm).
Described natural sand fineness modulus is medium sand and should meets < < regular concrete sand, the requirement of stone quality and test method standard > > JGJ52, described cement is that strength grade is that composite Portland cement or the strength grade of 32.5 grades is 32.5 grades of Portland blast furnace slag cements or ordinary Portland cement, described flyash is I level or II level flyash, described admixture is coal ash autoclaved brick masonry dedicated mortar admixture (Shanxi Kai Di building materials company produces KDH-L type), described water requires water for meeting < < the reinforcement of concrete water quality standard > > JGJ63.
A preparation method for coal ash autoclaved brick masonry dedicated mortar, it comprises the following steps: 1. by natural sand 1350～1550 Kg; Cement 183～337Kg; Flyash 32～60Kg; Admixture 2.15kg～7.15Kg; Water 215～250 Kg are by weight mixing by mechanical uniform; 2. the mortar 1. step being mixed mechanical stirring 3min.
The effect that the present invention compared with prior art improved have following some: 1. effectively reduce the water consumption of common masonry mortar, improve workability, improve density; 2. later strength increases comparatively fast, also effectively improves its anti-anti-freezing property and endurance quality of mixing; 3. improve the cohesive force of mortar and brick, improve mortar performance, reduce cost.
