Description

Composite cement base reinforcer
Technical field
The present invention relates to the architecture engineering material technical field, specifically a kind of composite cement base reinforcer.
Background technology
High-early-strength concrete is be accompanied by construction requirement that construction work improves day by day and service requirements and produce development.In recent years, along with the high stratification of modern building, greatly across harshization of change, lightweight, undergroundization and environment for use, concrete intensity and weather resistance are had higher requirement, make high strength, high performance concrete develop rapidly.In engineering construction, improving construction quality and reducing construction costs is ubiquitous conflict, and under the prerequisite that guarantees construction quality, shortening the construction period not only can Early Opening to Traffic, and can reduce a large amount of maintenances and executive cost.High-strength concrete is applied early abroad, and the concrete up to 80MPa has all been applied in a lot of areas, the world at present.
On the other hand, produced a large amount of wastes in concrete structure construction and demolishing process, China reaches more than 300,000,000 tons because of the building solid castoff of removing the building generation every year, and wherein great majority are discarded concretes.Yet few for the effective treating method of these waste and old concretes, traditional treatment process is mainly to transport countryside air storage or landfill to, the utilization of this low level is actually a kind of waste of resource; Producing concrete needs a large amount of mineral aggregates, and mine resources, as a kind of Nonrenewable resources, need to be protected.Therefore, discarded concrete is carried out to regeneration, can save natural resource, reduce waste and stack place, protection of the environment, have good Social benefit and economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned existing defect, and a kind of composite cement base reinforcer is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of composite cement base reinforcer is provided, comprise following component and weight proportion: water-resisting agent: 35~60 parts, consist of slag micropowder 20~45%, phosphogypsum 45~70% and diminishing component 3~10%; Expansion component: 9~20 parts, consist of recessed native 0.1~0.6%, non-ionic type defoamer 0.03~0.15%, ether of cellulose 5~10%, slag micropowder 55~70% and water reducer 20~30%; Calcium stearate: 25~60 parts.
Further, the weight percent of described composition water-resisting agent is slag micropowder 30%, phosphogypsum 65%, diminishing component 5%.
Further, described slag micropowder is S75~S105 breeze.
Further, in described phosphogypsum, the content of active silica is not less than 80%wt.
Further, described diminishing component is one or both in polyethers poly carboxylic acid or polyester poly carboxylic acid.
Further, the weight percent of described each composition of expansion component is: recessed native 0.4%, and non-ionic type defoamer 0.1%, ether of cellulose 6.6%, slag micropowder 66%, water reducer 26.9%.
Further, described recessed soil is that the raw ore attapulgite clay is calcined 1 hour~3 hours gained under 500 ℃~750 ℃.
Further, described ether of cellulose viscosity is 20,000~80,000 ether of cellulose.
Further, described ether of cellulose viscosity is 60,000 ether of cellulose.
The invention has the beneficial effects as follows, by product of the present invention, solid waste is obtained fully and the utilization of high added value, the cement concrete reinforcer prepared can effectively improve cement concrete in early days with the intensity of middle and later periods, be conducive to the cement concrete industry strategy of sustainable development, have social enviroment protection, energy-saving and emission-reduction meaning concurrently.Material of the present invention is beneficial to construction in enormous quantities, can be widely used in the concrete structure in the fields such as building, water conservancy, municipal traffic, ocean military project.
