Abstract
The invention discloses a C30 concrete preparation method, wherein the mass ratio of cement, sand, stones, water, a water reducer to fly ash in the concrete is 230:840:1100:138:4.26:60. With the ratio, the use amounts of the cement, the sand and the stones reach the minimum value within a reasonable range, so that the method reduces production cost. The C30 concrete is 160 +/- 20 mm in slump degree and satisfies the demand of C30 in pressure resistance and permeation resistance.
Description
Technical field
The present invention relates to a kind of C30 concrete matched ratio method.
Background technology
C30 concrete is general to be used on pile foundation, column and pressure-resisting plate partially, so require very high to concrete ultimate compression strength; In the proportioning that general production C30 concrete adopts, cement and the too high production cost that causes of stone consumption too high, or cement and the very few impermeability of mixed earth and the crushing resistance of causing of stone consumption do not reach requirement.
Summary of the invention
The object of this invention is to provide a kind of C30 concrete matched ratio method.
The technical solution used in the present invention is: a kind of C30 concrete matched ratio method, in this concrete, the mass ratio of cement, sand, stone, water, water reducer and flyash is 230:840:1100:138:4.26:60.
As a further improvement on the present invention, described sand is coarse sand.
As a further improvement on the present invention, described coarse sand is the coarse sand not deducting water content.
As a further improvement on the present invention, described water is the water content not adding sand.
As a further improvement on the present invention, described cement is the cement of P.O42.5 level.
As a further improvement on the present invention, cobble-stone diameter is 10mm-26mm.
The invention has the beneficial effects as follows: use this proportioning, in rational scope, press minimum quantity use cement, stone and yellow sand, decrease production cost, the mixed earth slump produced is within 160 ± 20mm, and concrete anti-compression and impermeability meet C30 requirement completely.
