Description

A kind of preparation technology of build concrete
Technical field
The invention belongs to building material field, and in particular to a kind of preparation technology of build concrete.
Background technology
Concrete generally refers to make Binder Materials with cement, and sand, masonry gather materials;With water(Additive and admixture can be contained)Press Certain proportion coordinate, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering.Coagulation Soil is referred to by cementitious matter (organic, inorganic or organo-mineral complexing), granular aggregat, water and needs the chemistry for adding The compound of additive and mineral admixture by proper proportion mixing, or it is hardened after form compound with heap poly structure Material (is commonly with Binder Materials, water, fine aggregate, coarse aggregate), additive and mineral admixture are mixed when needing, by appropriate ratio Example coordinates.Concrete has abundant raw material, cheap, and the characteristics of simple production process, thus usage amount is increasing.Simultaneously The features such as concrete also has compression strength height, good endurance, strength grade wide ranges.These features make its use range very Extensively, not only used in various civil engineerings, it is exactly shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering etc., coagulation Soil is also important material.
In recent years, agricultural wastes resource had gradually obtained the attention of people, and to which, comprehensive research on utilization is also obtained Some progress.Its main application for be used as fuel, fertilizer, feed, using bacterium base-material.But the agricultural wastes being utilized every year Quantity is relatively limited, most of all by centralized burning process, in turn results in serious atmosphere pollution and resource loss, in addition country Order forbids agricultural wastes to be incinerated, and causes a large amount of agricultural wastes to be deposited in field.
Concrete in hardening process is poured, as the reasons such as chemical shrinkage, shrinkage and drying shrinkage can cause volume contraction.And And unit cement consumption and water consumption are more, volume of concrete is bigger, and moisture evaporation is faster, then shrink more obvious.Ordinary circumstance Under, it is 0.04-0.09% per cubic meter of concrete shrinkage value, causes concrete to produce cracking, seepage, steel bar corrosion, prestressing force and damage The adverse consequences such as mistake.Concrete prepares enterprise while concrete quality is improved, in addition it is also necessary to reduce the cost of material of concrete And simplify preparation technology.
The content of the invention
Present invention aim to address in prior art concrete preparation technology many defects, through lot of experiments and spy Rope, reduces cost of material, simplifies preparation technology, and the concrete material for preparing possesses big intensity, light weight and resists The advantages of freezing corrosion-resistant.
To achieve these goals, technical scheme is in the following way realizing:
A kind of preparation technology of build concrete, which comprises the steps:Step 1)Broken, calcining and mixing, step 2)Water Solution and stirring, step 3)Crush and ball milling, step 4)Crush and stir, step 5)Mix thoroughly, stand and discharge.
Specifically, the preparation technology comprises the steps:
Step 1)Broken, calcining and mixing:Dolomite is crushed, 600 DEG C of calcining 30min, natural cooling, Ran Houyu is subsequently placed in Sawdust is according to 2:1 mass ratio is well mixed, and obtains component 1;
Step 2)Hydrolysis and stirring:By in hydrochloric acid solution that the mass fraction that dregs of beans is added to double weight is 30%, 50 are heated to DEG C, 50 DEG C of stirring hydrolysis 5 hours are maintained, mixing speed is 200rpm, and then addition accounts for the 12 of 1/5th mass parts of dregs of beans Sodium alkyl benzene sulfonate, stirs, and obtains final product component 2;
Step 3)Crush and ball milling:By lime stone and iron ore according to 2:3 mass ratio is well mixed, and then puts into pulverizer Particle is ground into, is kept the particle diameter of particle in below 1cm, is then sent to ball mill, be milled to the powder that particle diameter is 30-50 mesh, i.e., For component 3;
Step 4)Crush and stir:Broomcorn straw is ground into into broomcorn straw powder, then by broomcorn straw powder, river sand and chlorination The magnesium aqueous solution mixes, and is stirred 3 minutes with the mixing speed of 500 turns/min, obtains component 4;Wherein, broomcorn straw powder, river sand with And the mass ratio of magnesium chloride brine is 3:5:10;
Step 5)Mix thoroughly, stand and discharge:By addO-on therapy 2 in component 1, it is uniformly mixed and obtains the first mixture, then AddO-on therapy 3, is uniformly mixed and obtains the second mixture, addO-on therapy 4, water and normal silicate in the second mixture Cement, is uniformly mixed, and stands 20 minutes, is then discharged out, obtains final product concrete.
Preferably, the particle diameter of the river sand is 50-100 mesh;The concentration of the magnesium chloride brine is 10wt%;
Preferably, the step 5)In, the mass ratio of component 1, component 2, component 3, component 4, water and Portland cement For 3-5:1-2:5-8:10-15:3-5:15-26;
Preferably, the Portland cement is No. 42.5 Portland cements.
The beneficial effect that the present invention is obtained is primarily but not limited to the following aspects:
Dolime and sawdust mixing improve the uniformity of concrete pore, and adhesion strength is good, reduces weight concrete, and And it is effectively utilized discarded object;Stalk agricultural wastes possess the requirement such as antifreeze, freeze proof, impervious, but which are close as water reducer It is aqueous very strong, expand after water suction, poor adhesion and condensation are slow, and chlorine oxygen magnesium has the work of anticorrosive mildewproof to agricultural wastes With preventing the serious phenomenon of slow setting in its preparation process, improve the service life of product;Hydrolysis dregs of beans albumen is used as foaming Agent, with low cost, foaming size aperture excellent in uniform, stability and compatibility it is good;Employ in concrete formulation of the present invention Substantial amounts of cheap raw material, material combination rationally, greatly reduce the cost of product, and preparation process is simple is feasible, are adapted to scale Production, is suitably applied the fields such as electric pole, meteorological tower and floor construction body.
