Abstract
The invention discloses a super early-strength repairing material for a cement concrete. The super early-strength repairing material for the cement concrete is prepared from the following components by weight: 0.3-0.5 part of polycarboxylate superplasticizer, 2-3 parts of ferric nitrate, 0.3-0.5 part of polyving akohol, 1-3 parts of sodium sulfate, 10-15 parts of sulphate aluminum cement, and 78-86.4 parts of Portland cement, wherein the total parts of all the components are 100. The super early-strength repairing material has the advantages that an inorganic material is taken as a main material to prepare the super early-strength repairing material for the cement concrete, the cost is greatly lower than that of an organic mending agent, the defects of large shrinkage of an inorganic mending agent and untight combination with a base body are also overcome, and the super early-strength repairing material for the cement concrete has an excellent market prospect.
Description
Technical field
The present invention relates to a kind of cement concrete healant.
Background technology
Crackle and crack are the main forms of quality defect of concrete, once there is crackle in concrete, the degree of compaction of all of impervious measure and concrete self is by meaningless, extraneous erosion will be driven straight in, if can not repair in time, reinforcing bar, by Accelerated corrosion, causes whole armored concrete service life to shorten dramatically.Therefore, the repairing to crackle is particularly important.
Mending mortar in the market is multifarious, has epoxy resin, also quick-hardening cement, and these products also exist the shortcoming of selling at exorbitant prices a bit, the shortcoming that some existence are combined with matrix closely, repair efficiency is the best.
Summary of the invention
Goal of the invention: for the problems referred to above, it is an object of the invention to provide a kind of low cost, shrinks little and collective's compact cement concrete healant.
Technical scheme: a kind of cement concrete instant coagulant and mending agent, comprising by each component of following weight: polycarboxylate water-reducer 0.3-0.5 part, ferric nitrate 2-3 part, polyvinyl alcohol 0.3-0.5 part, sodium sulfate 1-3 part, sulphate aluminium cement 10-15 part, portland cement 78-86.4 part, each component amounts to totally 100 parts.
The water-reducing rate of described polycarboxylate water-reducer is 25%, moisture content is less than 3%.
Described ferric nitrate, sodium sulfate are industrial goods.
The alcoholysis degree of described polyvinyl alcohol is 88-92%.
Described sulphate aluminium cement, the strength grade of portland cement are 42.5.
Optimal, described cement concrete instant coagulant and mending agent, comprise by each component of following weight: polycarboxylate water-reducer 0.3 part, ferric nitrate 3 parts, polyvinyl alcohol 0.4 part, 2 parts of sodium sulfate, sulphate aluminium cement 14 parts, portland cement 80.3 parts.
Optimal, described cement concrete instant coagulant and mending agent, comprise by each component of following weight: polycarboxylate water-reducer 0.4 part, ferric nitrate 3 parts, polyvinyl alcohol 0.3 part, 1 part of sodium sulfate, sulphate aluminium cement 12 parts, portland cement 83.3 parts.
Optimal, described cement concrete instant coagulant and mending agent, comprise by each component of following weight: polycarboxylate water-reducer 0.5 part, ferric nitrate 2 parts, polyvinyl alcohol 0.5 part, 3 parts of sodium sulfate, sulphate aluminium cement 15 parts, portland cement 79 parts.
Optimal, described cement concrete instant coagulant and mending agent, comprise by each component of following weight: polycarboxylate water-reducer 0.4 part, ferric nitrate 1 part, polyvinyl alcohol 0.5 part, 2 parts of sodium sulfate, sulphate aluminium cement 11 parts, portland cement 85.1 parts.
Optimal, described cement concrete instant coagulant and mending agent, comprise by each component of following weight: polycarboxylate water-reducer 0.5 part, ferric nitrate 1 part, polyvinyl alcohol 0.3 part, 1 part of sodium sulfate, sulphate aluminium cement 13 parts, portland cement 84.2 parts.
Beneficial effect: compared with prior art, the invention have the advantage that with inorganic material be main preparation cement concrete instant coagulant and mending agent, cost relatively organic healant significantly declines, overcome again mineral-type healant and shrink the big shortcoming being combined defective tightness with matrix, have good market prospect.
