Abstract

The invention discloses a proportioning method of C30 concrete. The mass ratio of cement to sand to gravel to water to a water reducer to fly ash in the concrete is 225:865:1020:139:4.26:59. With the adoption of the ratio, minimum cement, stone and yellow sand are used in a reasonable range, the production cost is reduced, the slump of the produced concrete is in the range of 160 mm plus or minus 20 mm, and the crushing resistance and the permeability resistance of the concrete completely meet the requirements of C30.

Description

A kind of C30 concrete matched ratio method
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 225:865:1020:139:4.26:59.
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.
Embodiment
Embodiment:
A kind of C30 concrete matched ratio method, it is characterized in that the mass ratio of cement, sand, stone, water, water reducer and flyash in this concrete is 225:865:1020:139:4.26:59, sand is coarse sand, coarse sand is the coarse sand not deducting water content, water is the water content not adding sand, cement is the cement of P.O42.5 level, and cobble-stone diameter is 10mm-26mm.
Above embodiments of the present invention are described, but the invention is not restricted to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from present inventive concept.
