Abstract
The invention discloses energy-saving dry powder type building mortar which consists of the following raw materials in parts by weight: 260-330 parts of Portland cement or slag cement, 405-585 parts of common sand, 10-50 parts of electric furnace slag, 10-30 parts of scrap, 5-15 parts of dry powder lime, 2-5 parts of red mud, 3-5 parts of silt and 22.8-27.9 parts of dry powder latex, wherein all the raw materials are weighed according to the weight parts after being dried and screened, and then physically mixed to obtain the granular or powdery product; and the product in bags or in bulk is conveyed to a construction site and can be directly used after being mixed with 123-155 parts of water. The energy-saving dry powder type building mortar disclosed by the invention is highly energy-saving, green and environment-friendly and convenient to construct and store, has stable and reliable quality and can stay as long as the building.
Description
Technical field
The present invention relates to building material technical field, especially relate to a kind of novel energy-conserving dry powder building mortar.
Background technology
Tradition mortar is on-the-spot mixing type product, because its metering exactness is difficult to control, thereby causes mortar quality to have very great fluctuation process.In addition traditional mortar feedstock property is single, and in cohesion process of setting, moisture evaporation forms more hole; The contraction function of cement based hardenite and styrofoam differs greatly simultaneously, thereby the interface of styrofoam and mortar bonding inequality the higher stress that distributing, this stress is in thermodynamic (al) nonequilibrium state, trend towards being spontaneously evenly distributed, this effect and under extraneous effect, usually cause and the phenomenons such as wall crazing, infiltration, coat of plaster sky are swollen, come off cannot meet the different requirements of Modern New material of construction to mortar.
Summary of the invention
The problems referred to above that exist for prior art, the applicant provides a kind of energy-conservation dry powder type building mortar.High energy saving of the present invention, environmental protection, constructs convenient, be convenient to storage, steady quality is reliable, can with the same life-span of buildings.
Technical scheme of the present invention is as follows:
An energy-conservation dry powder type building mortar, each feed composition and parts by weight thereof are:
Silicate cement or slag cement (model is 32.5 ~ 52.5): 260 ~ 330 parts;
General sand: 405 ~ 585 parts;
Electric furnace slag: 10 ~ 50 parts;
Chip: 10 ~ 30 parts;
Dry powder lime: 5 ~ 15 parts;
Red mud: 2 ~ 5 parts;
Silt: 3 ~ 5 parts;
Dry powder latex: 22.8 ~ 27.9 parts;
Described chip can adopt rubble.
After various starting material component drying screenings are processed, weigh by weight, then carry out physical mixed, obtain particulate state or powder-like product, with form packed or in bulk, be transported to building site, add after 123 ~ 155 parts of water mix and stir and can directly use.
The technique effect that the present invention is useful is:
The present invention is a kind of dry-mix, and dry-mix is by the introducing of polymkeric substance, to have improved the flexibility of interfacial state and sizing agent itself, and function is good, accurate measurement, construction are convenient, has effectively guaranteed construction quality.Dry-mix is produced by concentrating, scattered distribution mode, and the various drawbacks such as of poor quality, dirty, random that efficiently solve that building-site mixing mortar exists, are convenient to civilized construction more.
The present invention adopts industrial waste as starting material in a large number, and save energy, reduces costs.Electric furnace slag, for steel-making steel scrap, is pulverized and sieving technology by slag, and as the filler of product of the present invention, its mechanical property is better than natural stopping composition, has good absorption property, and hardness is high, and weather resistance is strong.The contaminative waste residue of discharging when red mud is Aluminium industry extraction aluminum oxide, the essential mineral composition of red mud is aragonite and calcite, both can be used as aggregate, has again certain cementation, alkalinity is high, and cement has compatibility.Silt is the silted sandy soil of rivers Hu Dao, and its essential mineral is configured to quartzy and feldspar and clay, can be used as binding agent.
Embodiment
The present invention implements in accordance with the following methods: at normal temperatures, various solid raw materials are pressed to classify and pile up, by electronic weighing system, press predetermined parts by weight automatic Weighing, then carry out physical mixed, concentrate and to be dosed to pulverizer and to be ground into fine particle shape, uniform stirring obtains product, with form packed or in bulk, is transported to building site, after adding water and mixing and stirring, can directly use.
Embodiment 1 to embodiment 3 has prepared respectively the mortar that model is M5.0 ~ 10, when construction, according to building requirements, selects different model.Each raw material weight umber that three embodiment adopt is shown in Table 1, and unit is Kg.
