Abstract
Disclosed is a process for preparing high strength concrete, characterized in that, the constituents of the raw material include, cementing material 400-440kg, sand 570-750kg, crushed stone 1115-1400kg, water reducing agent 6.0-10.0kg, and water 110-140kg.
Description
Technical field
Patent of the present invention relates to a kind of method for preparing high-intensity concrete.
Background technology
In recent years, concrete PHC pile tube in Guangdong, provinces and cities such as Shanghai, Zhejiang, Fujian, Hainan, Jiangsu are applied, concrete tensile strength, Young's modulus, ultimate tensile strength and and time relation, thermal conductivity, thermal diffusivity, specific heat, linear expansivity, thermal insulation warming, creep and stress relaxation coefficient, constraint condition, curing condition, heat-insulating property etc. have material impact to large volume concrete structural temperature control design and construction simulation analysis.Now the normal concrete that generally adopts has himself inherent defective above-mentioned in some, and pile tube atmospheric steam curing time is long.。
Summary of the invention
Patent of the present invention provides a kind of method for preparing high-intensity concrete, uses the concrete of this preparation method's preparation, can shorten pile tube atmospheric steam curing time, accelerates the turnover of mould, and can reduce production costs.
The preparation method of patent of the present invention is such: the proportioning of composition of raw materials is: the proportioning of composition of raw materials is: agglutinate 400～440kg, sand 570～750kg, rubble 1115～1400kg, water reducer 6.0～10.0kg, water 110～140kg; Its feeding sequence is: sand adds agglutinate, dry mixing 15 seconds, and the water of adding 90% adds rubble, water reducer, adds all the other water of 10% more at last and mixes thoroughly.
This strong concrete is applied in the PHC pile tube, when concrete develops intensity by the hydrated cementitious sclerosis, cement also excites breeze development intensity, so can obtain potent fruit early,, can improve 10Mpa with intensity under the condition by original steam curing technology maintenance, use the concrete of this preparation method's preparation, can shorten pile tube atmospheric steam curing time, accelerate the turnover of mould, and can reduce production costs.
