Abstract
The invention discloses a cement admixture used for building ready-mixed dry mixed mortar and an application method thereof. The cement admixture comprises the following components: 45-98% of cement, 0-40% of mineral admixture, 0-15% of lime or gypsum and 0.1-5% of additive. 10-50% of cement mixture and 50-90% of sand are mixed, water with 10-20% weight of solid matter is added, stirring to be uniform is carried out, and the cement admixture is used for building construction. Dry ready-mixed mortar is divided into two parts, one part is the cement admixture, and the other part is baked sand. The two parts are separately stored and transported, quantitative cement is added in the scene, and mixing is carried out to obtain the mortar for building. Equipment investment and floor area of a ready-mixed mortar factory are greatly reduced, even the cement admixture is produced by a cement factory without requiring the read-mixed mortar factory, and social investment can be greatly saved.
Description
Technical field
The present invention relates to a kind of building trade premixing mortar that is mainly used in and use cement admixture, the invention still further relates to the method for use of this cement admixture.Premixing mortar for building is divided into dry mixing premix mortar and two kinds in wet companion's premix mortar.What the present invention related generally to is the premixing dry-mixed mortar, is called for short dry-mixed mortar.
Background technology
The tradition manufacturing of sand-cement slurry for building, use-pattern are that each component is mixed system at the construction field (site).Its shortcoming is: the first, dust, sound pollution are serious; The second, quality is not easy control; Three, material stacking floor space is big.Therefore, developed country has abandoned this scene and has mixed the system mode more than 90%, and uses specialized, commercial premixing dry-mixed mortar.
Existing manufacturing, the use-pattern of commercialization dry-mixed mortar is: in dry-mixed mortar plant; With cement, mineral admixture, lime or gypsum, additive, process dry-mixed mortar with the sand mixing of oven dry back (moisture content is less than 0.5%) and dispatch from the factory, add water at the construction field (site) and process mortar and use.Because the proportion of sand and cement, mineral admixture differs bigger, be difficult to mix uniform, and require great effort mix system after; In the process of turnover feed bin and transportation, very easily produce segregation owing to moving and jolting; Composition is uneven when causing using, performance inconsistency, and the mortar quality is a greater impact.
On the other hand, for preventing component moisture absorption sex change such as cement, cause making moist, luming of dry-mixed mortar; Therefore, in the production process, sand need dry to moisture content less than 0.5%; The cost of dry-mixed mortar per ton like this will increase dozens of yuan, and consumption per ton mark coal 6-10 kilogram.The premixing dry-mixed mortar amount of estimating China in 2015 will reach 500,000,000 tons, and only the sand oven dry is one, will cost 10,000,000,000 yuans, consume ten thousand tons of mark coal 210-350.The whole world will consume ten thousand tons of mark coal 1500-2000 more.Need add water again during on-the-spot the use and mix system, therefore, the baking operation of sand is uneconomic, and it is high to consume energy.
In addition, because the consumption of additive often seldom, have only below 1%, when dried mixing, be difficult to mixing, add the segregation of sand, the quality product of dry-mixed mortar is difficult to stable.
Therefore, the existing manufacturing of dry-mixed mortar, method of use are reasonable inadequately on flow scheme design, cause energy consumption high, and efficient is low, and the cycle is long, and quality product is difficult to guarantee.Existing in addition dry-mixed mortar function adopts tank-transport truck or the transportation of special-purpose dry-mixed mortar transport trolley, and facility investment is big, and logistics cost is higher.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of building premixing dry-mixed mortar with cement admixture and method of use thereof, first, overcome the defective of the high energy consumption that causes because of the oven dry sand in the existing manufacturing of existing dry-mixed mortar, the use, save energy; The second, solve the segregation problem that has now in dry-mixed mortar production, the transportation, under the prerequisite of save energy, improve the quality of products.Three, reduce the social investment of dry-mixed mortar factory and logistics.
Technical scheme of the present invention is following:
A kind of building premixing dry-mixed mortar is used cement admixture, it is characterized in that composed of the following components:
Cement 45-98%, mineral admixture 0-40%, lime or gypsum 0-15%, additive 0.1-5%;
Described mineral admixture is that a kind of in flyash, the slag or both mix by arbitrary proportion;
Described additive mainly comprises: water-holding agent, stablizer, air entrapment agent, redispersable latex powder, skimmer.
Described per-cent is weight percentage.
Described building premixing dry-mixed mortar is characterized in that with the method for use of cement admixture:
The cement admixture of 10-50% and the sand of 50-90% are mixed, add the water of solid substance 10-20%, stir, be used for building operation; Described per-cent is weight percentage.
Positively effect of the present invention is:
The first, the present invention mixes the premixing mortar separated into two parts with doing, and a part is a cement admixture; Another part is the sand of not drying.Two portions are separately deposited, and transportation adds quantitative the mixing of water and processes mortar for building to the scene.Significantly reduced the facility investment and the occupation of land of premixing mortar factory, even do not used premixing mortar factory, cement admixture is produced by the cement mill, can practice thrift hundred billion social investment.
The second, realize doing under the prerequisite of mixing premixing mortar commercialization, specialized production and using, practiced thrift the energy consumption cost of oven dry sand, and reduced environmental pollution.
Three, solve segregation problem in existing dry-mixed mortar production, the transportation, under the prerequisite of save energy, further improved quality product.
Four, produce cement admixture by special manufacturers such as cement mill, reduced facility investment;
Five, be convenient to many means transportations, such as having reduced logistics cost by common shipping vehicle transport.
