Description
Technical field
The present invention relates to a kind of composition of building dry powder and mortar, particularly a kind of block of building that can be widely used in the building trade is plastered and the high-strength building dry-mix on ground.
Background technology
Concrete being extensive use of under construction makes people begin to manage to improve concrete production efficiency and quality.The Britain that ready mixed concrete appeared at for two prewar the earliest.The concrete of this scale operation in professional factory, can directly use after transporting to the construction site by special-purpose transport mixer: thus the efficient of construction and the quality of building improved greatly.Nowadays, commerical ready-mixed concrete has developed into one of main material of construction.On the contrary, the production of mortar class building materials also is artificial at the construction field (site) mixed preparing always, and Europe produces the prefabricated mortar that has used a kind of dry powder at first.The same with precast concrete, this pre-manufactured product is accepted by people gradually, and is become a kind of product innovation with fastest developing speed in world's building material industry with good quality, construction easily.Dry-mix to be applied in Europe very general.Countries such as Germany, Austria, Finland adopt dry-mix as main mortar class building materials already.Dry-mix is also very rapid in the development in Asia.As far back as 1984, Singapore set up first dry blend factory, produced metope mortar product.The Malaysian dry blend production line of also having gone into operation in 1987.Along with developing rapidly of dry blend market, the dry-mix product category on the market, South East Asia also is enriched, and many product innovations such as gravity flowing levelling mortar, fireproof mortar, colored metope mortar etc. are all successfully put on market.At present in Asian countries and areas such as Korea S, Japan, Thailand, Malaysia, Singapore, large-scale professional dry-mix factory is arranged all.Produce the required raw material of dry-mix and mainly contain building materials such as sand, cement, and some consumptions chemical additive seldom.Although dry-mix is used widely, the workability of mortar, water-retentivity and cohesive force and become the difficult problem that industry needs to be resolved hurrily with the coupling of basic unit's (for example materials for wall).
Summary of the invention
The technical problem to be solved in the present invention is: traditional mortar mixes inhomogeneous, impure, silt content is excessive, no water retaining function, bleeding is serious and produce separation phenomenon, cause the quality instability, big for environment pollution, waste of material is big, do not make mechanical execution, be not easy to carry, the technical problem that labour intensity is high the invention provides a kind of dry-mix.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dry-mix, comprise cement, yellow ground, flyash and densification powder, and the mass percent of its component is in the prescription:
Cement: 15%;
Yellow ground: 76%;
Flyash: 6%;
Densification powder: 2.9985%;
Wilkinite: 0.0015%.
The ether of cellulose that adds mass percent 0.5% among the present invention in described prescription has effectively increased the applicable performance of prescription, and the water reducer of mass percent 0.2% can effectively reduce the water consumption of mortar mix.
Adjust the volume of high molecular cellulose ether and Peng Run soil among the present invention, to increase by 0.3% high efficiency water reducing agent again after its ratio cooperation according to 1:0.003, improve the mortar early strength more than 80%, ether of cellulose mainly increases the cohesive strength of mortar, 0.3% ether of cellulose 28d cohesive strength can reach more than the 0.5MPa, make and hold wherein mortar workability raising, thereby reach mortar construction and mortar various aspects of performance.
Preparation technology of the present invention has following steps:
A. yellow ground pre-treatment: yellow ground is dried scalping, yellow ground oven dry carrying out the again dusting cover after the scalping;
B. prepare burden: the yellow ground behind the 76 mass parts dusting covers, 15 mass parts cement, 6 mass parts flyash, 3 mass parts densification powders and 0.0015 part of wilkinite;
C. the thing powder mixes: the thing powder mixes into work in-process dry mixing sand powder at mixing machine;
D. the husky powder of dry mixing uses: husky powder of dry mixing and water ratio 100: 13～15 stir into dry-mix.
The generation that the weight of the material that the thing powder occurs under action of gravity of can avoiding the agravic formula mixing machine that mixing machine adopts among the present invention, agravic formula mixing machine does not wait, the material skewness causes the off quality of dry-mix.
Yellow ground drying unit among the present invention is three a backhauls baking sand device, and three backhauls baking sand can guarantee that the moisture content in the yellow ground is dried, and the assurance yellow ground is avoided occurring cement and sneaked out in the journey because the moisture content in the yellow ground causes caking dried in the dried drying of sneaking out in the journey in later stage.
The transportation of the husky powder of the dry mixing among this preparation technology can adopt multiple mode to transport, and can packedly transport, and transports in the finished product jar of can packing into, also directly transports in the bulk vehicle, satisfies the transportation of various different needs.
Can in material, add 0.5% ether of cellulose of material total mass and 0.2% water reducer in the preparation process of the present invention, ether of cellulose can increase the environmental performance that prescription is suitable for effectively, water reducer can reduce the water consumption that mortar mixes and stirs effectively, can reduce the usage quantity of water.
The invention has the beneficial effects as follows that the present invention stirs mortar with conventional on-site and compares, use building dry-powder more economical to material produce trade mark end user, no starting material holding cost does not have waste, does not have artificial stirring expense, reduces labour intensity; Premixing mortar is in factory automation production, and its steady quality guarantees and raising building operation quality that as the intensity height, anti-cracking is prevented peeling off water-impervious etc.; Be suitable for mechanized construction, such as: the storage in bulk of building dry-powder, air conveying, machine spraying etc.Thereby the raising construction quality is increased work efficiency exponentially, reduces construction cost, just improves the overall efficiency of building greatly; The handiness height of producing can be made the power-product of superior performance according to different requirement/prescriptions, and product innovation emerges in an endless stream, and the construction site free from dust benefits environment and reaches civilized construction, can greatly reduce disease propagation.
