Abstract
The invention relates to the technical field of concrete, in particular to a concrete additive. The concrete additive comprises the following components in parts by weight: 10-30 parts of modified cement, 10-20 parts of modified bentonite, 1-3 parts of nanometer silicon dioxide, 1-5 parts of a water reducing agent, 0.3-0.8 part of alkyl sodium sulfonate, 10-20 parts of gypsum powder, 1-5 parts of a wet dispersing agent, 0.3-0.8 part of a stabilizing agent, 0.2-0.5 part of an anti-freezing agent, 1-6 parts of a corrosion inhibitor and 10-25 parts of deionized water. The concrete additive has the beneficial effects that the compressive property of concrete can be greatly improved, and meanwhile, the durability of the concrete can be improved; the modified cement and the modified bentonite are utilized, so that the penetrating performance is greatly improved; besides, the corrosion inhibitor and the anti-freezing agent are added, so that performances of concrete are improved from multiple aspects, the service life of the concrete is prolonged, and the maintenance cost of a concrete building is reduced.
Description
Technical field
The present invention relates to technical field of concrete, especially a kind of concrete additive.
Background technology
Concrete is one of contemporary topmost civil engineering material.It is by gelling material, and particulate state is gathered materials (also referred to as aggregate), water, and the admixture added if desired and adulterant are prepared by a certain percentage, through uniform stirring, closely knit shaping, the artificial stone material of one of maintenance sclerosis.Concrete has abundant raw material, cheap, the simple feature of production technique, thus makes its consumption increasing.Simultaneously also to have ultimate compression strength high for concrete, good endurance, the features such as strength grade wide ranges.These features make its use range very extensive, and not only using in various civil engineering work, is exactly shipbuilding, mechanical industry, the exploitation of ocean, geothermal engineering etc., and concrete is also important material.
During concrete is applied in Practical Project, often be exposed to various comparatively harsh environment, as the intrusion of environment corrosive medium, the change of ambient temperature and humidity, freeze-thaw cycle destroy and part concrete works is often in heavy load wearing and tearing etc., and these external conditionss will have a strong impact on concrete work-ing life.Therefore, needing in concrete, add protective material and carry out provide protection to concrete, there is function singleness, technical deficiency to concrete maintenance effect difference in existing concrete additive.
Summary of the invention
The technical problem to be solved in the present invention is: overcome deficiency of the prior art, and providing a kind of can improve concrete toughness, ultimate compression strength and the concrete additive of working life.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of concrete additive, the mass parts of described concrete additive is composed as follows: modified cement 10-30 part, modified alta-mud 10-20 part, nano silicon 1-3 part, water reducer 1-5 part, sodium cetanesulfonate 0.3-0.8 part, terra alba 10-20 part, Ricinate 1-5 part, stablizer 0.3-0.8 part, frostproofer 0.2-0.5 part, rust inhibitor 1-6 part, deionized water 10-25 part.
Further, described water reducer is aliphatic hydroxyl sulphonate high efficiency water reducing agent.
Further, described modified alta-mud is for being calcium base organics modifications wilkinite.
Further, described water reducer is composite water-reducing agent, and the mass parts of described composite water-reducing agent is composed as follows: calcium lignin sulphonate 10-15 part, Triaethanolamine 6-8 part, sulfonate type aqueous polyurethane 2-5 part, aluminum oxide 2-5 part, calcium chloride 2-6 part.
Further, the mass parts of described stablizer is composed as follows: trolamine 5-10 part, zinc nitrate 10-20 part, water 40-50 part.
Further, the mass parts of described concrete additive is composed as follows: modified cement 20 parts, modified alta-mud 15 parts, nano silicon 2 parts, water reducer 3 parts, sodium cetanesulfonate 0.5 part, terra alba 15 parts, Ricinate 3 parts, stablizer 0.5 part, frostproofer 0.4 part, rust inhibitor 4 parts, deionized water 18 parts.
Adopt the beneficial effect of technical scheme of the present invention to be: concrete additive of the present invention can increase substantially concrete compressive property, can concrete weather resistance be improved simultaneously.Use modified cement and modified alta-mud in the present invention, penetrating quality increases substantially, and containing rust inhibitor and frostproofer in composition, improves concrete performance, extend concrete work-ing life, reduce the maintenance cost of concrete construction from many aspects.
