Abstract
The invention discloses a formula of high-intensity cement paste. According to the formula, the high-intensity cement paste consists of cement, water, high-activity metakaolin, and a sodium polyacrylate or naphthalenesulfonic acid and formaldehyde condensation product water reducing agent, wherein the mass ratio of the cement to the water is 1:(1-0.6); the using amount of the high-activity metakaolin is 5 to 10 percent based on the mass of the cement; and the using amount of the sodium polyacrylate or naphthalenesulfonic acid and formaldehyde condensation product water reducing agent is 0.3 to 0.6 percent based on the mass of the cement. The intensity of the cement paste which is prepared by the technical scheme can reach 15 MPa, and is improved by about 5 percent compared with that of the conventional cement paste under the same condition.
Description
Technical field
The present invention relates to a kind of prescription of high strength cement slurry.
Background technology
Grout is most important injecting paste material.Be mainly used in the reinforcing of engineerings such as tunnel, ground, culvert, dam, also be used for fields such as grouting for water-blocking, fluid injection fire-fighting.
Now, the basic recipe of domestic water mud is: cement: water=1:1～0.8.Sometimes, in order to improve the setting rate of grout, add a spot of water glass.Grout solidifies later intensity and is generally about 10MPa.
Mainly contain following two kinds of grout formula techniques at present, a kind of prescription of ortho-water mud is: cement: water=1:1～0.8.Grout solidifies later intensity and is generally 10MPa.
This technological shortcoming is:
The first, the shortcoming of prior art one mainly is that intensity is low.Grout solidifies later intensity and is generally about 10MPa.
The second, the grout calculus rate of prior art for preparing is low, generally has only (the calculus rate of grout is meant the volume of formation cement stone and the ratio of grout volume) about 70%.
Another kind of prior art is water glass-sprayed concrete, claims the biliquid slurry again, and its prescription is:
Cement: water=1:1～0.8, water glass consumption are 3～6% of cement consumption.Grout solidifies later intensity and is generally 10MPa.
This technological shortcoming remains 2 points:
The first, the shortcoming of prior art one mainly is that intensity is low.Grout solidifies later intensity and is generally 10MPa.
The second, the grout calculus rate of prior art for preparing is low, generally has only (the calculus rate of grout is meant the volume of formation cement stone and the ratio of grout volume) about 70%.
Summary of the invention
Technical problem to be solved by this invention is to improve the set strength of grout and the calculus rate that suitably improves grout.
In order to solve the problems of the technologies described above; The present invention provides a kind of prescription of high strength cement slurry; The prescription of said high strength cement slurry is to be made up of cement, water, high-activity metakaolin, ZX-I or naphthalene sulfonic acidformaldehyde condensation product water reducer, and wherein: the mass ratio of cement and water is 1:1～0.6; The consumption of high-activity metakaolin is 5～10% of a cement quality; The consumption of ZX-I or naphthalene sulfonic acidformaldehyde condensation product water reducer is 0.3～0.6% of a cement quality.
Beneficial effect of the present invention is:
1, the grout intensity of technical scheme preparation of the present invention can reach 15MPa, under equal conditions, and than the grout intensity raising about 50% of present use.
2, the calculus rate of the grout of technical scheme preparation of the present invention can reach 85%, and under equal conditions, than the grout intensity raising about 15% of present use, the raising rate is 21%.
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment
The present invention provides a kind of prescription of intensity grout, and the prescription of said high strength cement slurry is to be made up of cement, water, high-activity metakaolin, ZX-I or naphthalene sulfonic acidformaldehyde condensation product water reducer, and wherein: the mass ratio of cement and water is 1:1～0.6; The consumption of high-activity metakaolin is 5～10% of a cement quality; The consumption of ZX-I or naphthalene sulfonic acidformaldehyde condensation product water reducer is 0.3～0.6% of a cement quality.
The calcium hydroxide reaction that this technological enhanced mechanism produces when mainly being active aluminium sesquioxide and active silica and the hydrated cementitious in the metakaolin generates cement stone ore things such as hydrated calcium silicate and drated calcium aluminate, the set strength of raising grout; Simultaneously, water reducer has lowered the consumption of water, and intensity further improves.
The principle that this technology improves grout calculus rate is that the metakaolin particle is tiny, has certain suspension property, has stoped the sedimentation of cement granules, thereby has improved the calculus rate of grout to a certain extent.
