Abstract
The present invention relates to a cement glue with adjustable performances, wherein the cement glue is specifically used for filling of an insulator to form a permanent connection, high strength repair of mortar, and reinforcement of a high strength grouting material or production of a high strength prefabricated component. The cement glue of the present invention comprises the following raw material components, by weight, 40-55% of cement, 4-8% of a mineral admixture, 33-50% of sand, 0.3-0.6% of a water reducer, 0.04-0.14% of a slump loss inhibitor, 0.04-0.08% of anti-cracking fibers, and 0.02-0.05% of methyl cellulose. Compared with other cement glues, the cement glue of the present invention has characteristics of good workability, complete functions, good comprehensive performance, and significant early strength enhancement effect, wherein 1 day compressive strength is 40-70 MPa, 11 day compressive strength is 80-90 MPa, 28 day compressive strength is 85-95 MPa, and no corrosion is generated to reinforcing steel bars.
Description
Technical field
The present invention relates to the adjustable cement glue of a kind of performance, make it permanent connection, high-strength mending mortar and reinforcing high-strength grouting material or make high-strength prefabricated member especially for filling insulator.
Technical background
Along with the development of China's economic construction, the performance of cementing agent is proposed to multi-functional requirement.Domestic existing cement glue shrinks larger, easily produces crack, and intensity is low, and gain in strength is slow, supports for reaching as early as possible the general steam-cured and water that needs 40 hours to 60 hours of the intensity of dispatching from the factory, and there will be strength degradation 28 days time.Steam-cured, water is foster, and not only technique is loaded down with trivial details, cost is higher, and quality accident does not with great difficulty appear in time control.
Summary of the invention
It is can shrinkability little that the technical problem that the present invention solves is to provide one, and cementing agent workability is good, early stage and later strength is high, and to the effect of reinforcing bar non-corroding, production technique is simple, the adjustable cement glue of lower-cost a kind of performance.
Technical scheme of the present invention is:
The present invention includes the weight percent component of following raw materials according: cement 40%-55%, mineral admixture 4%-8%, sand 33%-50%, water reducer 0.3%-0.6%, slump-loss inhibitor 0.04%-0.14%, anti-crack fiber 0.04%-0.08%, methyl cellulose ether 0.02%-0.05%.
Described cement is the mixture of 42.5 grades of ordinary Portland cements and 42.5 grades of aluminosulfate cements, by weight, and normal silicate water: aluminosulfate cement=1-99: 99-1.
Described mineral admixture: silicon ash, II level flyash or S75 level slag micropowder more than two kinds mix.
Described sand is preferably: broken quartz sand or natural river sand, particle diameter: 0.08mm-1.0mm.
Described water reducer is preferably: polycarboxylate water-reducer, naphthalene water reducer, sulfamate water reducer, aliphatic water reducing agent;
Described loss of slump inhibitor is preferably: Sunmorl N 60S, boric acid, citric acid, tripoly phosphate sodium STPP.
Described ether of cellulose is preferably: methyl cellulose ether.
Cement of the present invention is one of main raw material, the cement glue of preparation have workability good, early strong, high-strength, shrink little, excellent in durability, material cost is low, makes full use of industry byproduct, has good economic benefit and social benefit.
In use procedure of the present invention, do not need steam-cured and water to support, time of coagulation is adjustable, and gain in strength is very fast, and later strength sustainable growth, shrinks less, good endurance with the test specimen of this preparation.
When the present invention is used as insulator cementing agent, cohesive strength is high, insulator reliable product quality; During as mending mortar, good with mend bond effect; Have fast hard, early strong effect with the prefabricated components that this cementing agent is made, template turnover is fast, and production efficiency is high.
The present invention can adjust raw-material mixing ratio according to the service requirements of different user, reaches different functional requirements.As: degree of mobilization, water-reducing rate, the early requirement such as strong, time of coagulation, endurance quality.Production technique is simple, and cost is lower.
Invention effect
The present invention is cement glue, through various performance tests and test, has following features and function:
1, the present invention is compared with other cement glue, and workability is good, multiple functional, good combination property, early strong reinforced effects are obvious.One day ultimate compression strength 40-70MPa, 11 days ultimate compression strength 80-90MPa, 28 days ultimate compression strength 85-95MPa, and to the effect of reinforcing bar non-corroding.
2, cement glue production technique of the present invention is simple, and material cost is low, makes full use of industry byproduct, also have early strong, workability is good, improves cement glue mechanical property, little loss of slump comprehensively.The cement glue product surface shrinkage crack of moulding is few, can comprehensively improve the endurance qualities such as the impermeability, frost resistance, carbonization resistance of cement glue.
3, cement glue of the present invention is adjustable time of coagulation, does not need in early days steam-curedly can reach fast hard, early strong effect.
