Description
Technical field
The invention belongs to construction engineering technical field, be specially a kind of building reinforce concrete and preparation method thereof.
Background technology
Reinforce, refer to that or owner not enough to reliability requires that the load larrying member of raising reliability, component and relevant portion thereof are taked enhancing, local replacing or adjust the measures such as its internal force, make it have the security required by current designs specification and owner, weather resistance and suitability.Conventional reinforcement means has: 1, reinforcement method of enlarging section: this method construction technology is simple, strong adaptability, and has ripe design and construction experience; Be applicable to the concrete reinforcing of beam, plate, post, wall and ordinary construction thing; But the wet trade time of site operation is long, production and life are had a certain impact, and the buildings headroom after reinforcing has certain reduction.2, replace concrete strengthening method: advantage and the section-increased method of this method are close, and do not affect the headroom of buildings after reinforcing, but the shortcoming that the wet trade time of same existence construction is long; Be applicable to pressure zone concrete strength on the low side or have the reinforcing of the concrete bearing component such as beam, post of major defect.3, have bonding steel-encasing strengthening method: this method also claims Wet-enclosing Steel Reinforcement, stressed reliable, easy construction, work on the spot amount are less, but steel using amount is comparatively large, and should not for more than 6000C high temperature place in unguarded situation; Be applicable to use and do not allow to enlarge markedly former sectional dimension of members, but require the concrete structure reinforcement increasing substantially its supporting capacity.4, affixing steel plate reinforcement method: this method quick, on-the-spot wet-less operation of construction or a small amount of wet trade such as only to plaster, affect little on production and life, and do not make significant difference to primary structure outward appearance and original headroom after reinforcing, but consolidation effect depends on adhesion process and operant level to a great extent; Be applicable to bear Static behavior and be in the reinforcing by curved or tension member in normal humidity environment.5, fibre reinforced plastics method for strengthening is pasted: except there is the similar advantage of affixing steel plate, also have that corrosion resistant is turbid, humidity, increase the advantages such as dead load, durable, maintenance cost is lower hardly, but need special fire prevention process, be applicable to the concrete structure member of various stressed character and general structures.6, filament-winding method: relative merits and the section-increased method of this method are close; Be applicable to the reinforcing of concrete structure member Beams Oblique Section Carrying Capacity deficiency, maybe need occasion compression member being applied to lateral confinement power.7, crab-bolt anchoring method: this method is applicable to transformation that strength grade of concrete is the concrete bearing structure of C20 ~ C60, reinforcing; Be not suitable for said structure and the light structures of seriously weathering.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provides a kind of building reinforce concrete and preparation method thereof, and this concrete has that ultimate compression strength is high, difficult drop-off, the feature that overall performance is superior.
Building reinforce concrete of the present invention is made up of the component of following parts by weight: aluminosulfate cement 64 ~ 76 parts, melamine high-efficiency water-reducing agent 5 ~ 6 parts, lignocellulose 18 ~ 22 parts, 8 ~ 12 parts, boron mud, Strontium carbonate powder 8 ~ 12 parts, dinonylnaphthalene sulfonic acid 6 ~ 9 parts, polyvinylpolypyrrolidone 8 ~ 10 parts, illite 12 ~ 15 parts, white carbon black 10 ~ 12 parts, Sodium hexametaphosphate 99 6 ~ 9 parts, 23 ~ 27 parts, water.
As optimization, this building reinforce concrete, is made up of the raw material of following parts by weight: aluminosulfate cement 66 parts, melamine high-efficiency water-reducing agent 5 parts, lignocellulose 20 parts, 9 parts, boron mud, Strontium carbonate powder 9 parts, dinonylnaphthalene sulfonic acid 6 parts, polyvinylpolypyrrolidone 9 parts, illite 13 parts, white carbon black 12 parts, Sodium hexametaphosphate 99 7 parts, 25 parts, water.
As optimization, this building reinforce concrete aluminosulfate cement used, within 28 days, ultimate compression strength reaches 42.5MPa.
Prepare the concrete method of this building reinforce, comprise the following steps:
A, the boron mud of described parts by weight, Strontium carbonate powder are ground into 200 object powder, then mix with the dinonylnaphthalene sulfonic acid of described parts by weight, polyvinylpolypyrrolidone;
B, the illite of described parts by weight, white carbon black, Sodium hexametaphosphate 99 made after 200 order powder mix, cool after being heated to 610 ~ 620 DEG C;
C, the aluminosulfate cement of described parts by weight, melamine high-efficiency water-reducing agent, lignocellulose, water are joined in stirrer and stirs 10 minutes with the speed of 450 ~ 550 turns/min; Then the mixture that adds successively in step a, step b stirs 20 minutes with the speed of 600 ~ 800 turns/min.
Treat reinforcing position during use and carry out form for seal, then inject this building reinforce concrete and vibrate; Meet after form removal requirement until concrete strength, by form removable, and conventional maintenance is carried out to reinforcing position.
Building reinforce concrete of the present invention, not only has higher ultimate compression strength and folding strength, and well can combine with existing concrete, difficult drop-off, and overall performance is superior, is extremely suitable for the reinforcing that concrete works damages position.Specifeca tion speeification is as table 1.
