Description
Technical field
The present invention relates to commerical ready-mixed concrete technical field, the especially manufacture method of commerical ready-mixed concrete special glue ramming material.
Background technology
Commerical ready-mixed concrete typically prepares production with 42.5,52,5 class g cements at present, fill the mineral admixture such as breeze, flyash as required, owing to concrete production technology limits, it is difficult to uniform for several material stirrings in short time, the homogeneity causing concrete quality is poor, concrete manufacturing cost is high, the drawbacks such as concrete overall durability is poor.
Summary of the invention
It is an object of the invention to provide a kind of quality stability special raw material of good concrete, thus improve the quality uniformity of commerical ready-mixed concrete, durability.Its technical scheme is: the material prescription making commerical ready-mixed concrete special glue ramming material is: clinker+desulfurated plaster+complex mineral blending material, its material prescription weight ratio is: clinker 20～30%, desulfurated plaster 4～6%, complex mineral blending material 64～76%;The preparation method of commerical ready-mixed concrete special glue ramming material: by 20-30% grog, 4-6% desulfurated plaster grinding, specific surface area controls between 350-400m/kg, then mix complex mineral blending material 64-76% through metering, pneumatic agitation homogenizing facility mixes；SO3: between 2.5-3.0%, the effective granule of grain composition: 3-32um accounts for 70%-80%, C3A content ＜ 5%；Seven days comprcssive strength 21MPa, 28 days comprcssive strength 40MPa;Complex mineral blending material is made up of zeolite powder, superfined flyash, slag micropowder, and its formulation weight ratio is: zeolite powder 3-5%, superfined flyash 30-40%, and remaining is slag micropowder;The preparation method of complex mineral blending material is: zeolite powder zeolite separate grinding, and its specific surface area is 400-500 m/kg；Superfined flyash is formed by II grade of power plant flyash separate grinding, and its specific surface area is 500-600 m/kg, loss≤8.0%；Slag micropowder is formed by granulated blast-furnace slag separate grinding, and its specific surface area is 400-450 m/kg, S95 level.
The present invention successfully produces stay-in-grade commerical ready-mixed concrete special glue ramming material, improve the quality uniformity of concrete gel material, enhance the uniformity of concrete quality, solve concrete quality instability, the difficult point of poor durability perplexed for many years, reduce the manufacturing cost of commerical ready-mixed concrete, improve the quality of commerical ready-mixed concrete, expand comprehensive competition advantage further.
The present invention utilizes less clinker to produce commerical ready-mixed concrete special glue ramming material, substitutes concrete gel material completely, is greatly improved the stability of Quality of Commercial Concrete, commerical ready-mixed concrete cost is made to reduce, steady quality, durability is long, is suitable for popularity and uses.
Detailed description of the invention
Draw according to many experiments, make the material prescription of commerical ready-mixed concrete special glue ramming material: clinker+desulfurated plaster+complex mineral blending material is serial, its material prescription weight ratio is: clinker: 20～30%, desulfurated plaster: 4～6%, complex mineral blending material: 64～76%, wherein complex mineral blending material is made up of zeolite powder, superfined flyash, slag micropowder, and its formulation weight compares: zeolite powder: 3-5%, superfined flyash: 30-40%, remaining is slag micropowder.The preparation method of complex mineral blending material is: zeolite powder zeolite separate grinding, and its specific surface area is 400-500 m/kg；Superfined flyash is formed by more than II grade of power plant flyash separate grinding, and its specific surface area is 500-600 m/kg, loss≤8.0%；Slag micropowder is formed by granulated blast-furnace slag separate grinding, and its specific surface area is more than 400-450 m/kg, S95 level.
Use best particle size gradation principle, it is ensured that the uniformity of inside concrete organizational structure, improve concrete density, make the durability of concrete be improved.The minimizing of grog consumption reduces the heat of hydration and expands the destruction to concrete brought, and can not only reduce energy resource consumption, reduce production cost, also improve the durability of concrete.
The process advantage of the present invention: this cementitious matter can substitute concrete gel material completely, it is possible to additionally incorporate of mineral admixture is eliminated during concrete production, decrease operation, decrease blanking and measure the quality fluctuation brought, it is greatly improved the stability of Quality of Commercial Concrete, concrete particle grating is more reasonable, and concrete density is improved, and the durability of concrete is improved significantly.
The technical advantage of the present invention: this cementitious matter can be used for C10-C60, produces intensity with 42.5 class g cements on year-on-year basis and can exceed about 3-5MPa.The heat of hydration that this cementitious matter is relatively low and higher Sulphate-resistant property, cannot be only used for normal concrete, it is also possible to adjust formula proportion as required, for special concretes such as mass concrete, sulfate resistance concrete, water-tight concrete and frost thawing resistance concretes.Concrete performance is less than 2.5 × 10 up to impervious more than P10, sulfate resistance salt corrosion grade up to more than KS120, more than freeze thawing resistance F200, chloride ion transport coefficient-12m2/s。
The design advantage of the present invention: while improving concrete quality stability and endurance quality, the dispensing cost of commerical ready-mixed concrete can be substantially reduced, reduce the consumption of clinker 20% in concrete, reduce energy resource consumption and resource consumption, reach the purpose of energy-saving and cost-reducing minimizing CO2 emission.
