Abstract

Pumpable fair-faced concrete is composed of the following compositions in parts by weight: 290-300 parts of cement, 170-180 parts of water, 840-850 parts of river sand, 760-780 parts of 1-2 pebble, 170-190 parts of 0-5 pebble, 60-80 parts of mineral powder, 60-70 parts of fly ash, and 7.0-9.0 parts of a polycarboxylic acid additive. The provided pumpable fair-faced concrete solves the conveying problem of fair-faced concrete by using a conveying pump during construction, and also guarantees demands of buildings on appearance and quality of fair-faced concrete.

Description

A kind of pumping clear-water concrete
Technical field
The present invention relates to building material field, be specifically related to a kind of pumping clear-water concrete.
Background technology
Clear-water concrete, also known as decorative concrete, is gained the name because it has decorative effect.It belongs to one-time cast-forming; do not do any external decoration, directly adopt the natural surface effect of onsite concrete as facing, be therefore different from normal concrete; surfacing is smooth, uniform color, corner angle clearly demarcated, without clashing and breaking and pollution, be just coated with one deck or two-layer transparent protective material on surface.Clear-water concrete requires its mixture uniform color, has good workability (mobility, cohesiveness and water-retentivity), must not occur segregation and bleeding.In pumping construction, not only require that there is good mobility.Also require good cohesiveness, fresh concrete so just can be made to be easy to form and laminated segregation phenomenon does not occur, and cement slurry is as concrete gelling material, its rheological property will directly affect concrete serviceability.
With regard to clear-water concrete itself, be unfavorable for that transferpump is carried, can only repeatedly prepare and do great many of experiments and solve structures for the perception of clear-water concrete and specification of quality, and the transport problem of clear-water concrete.
Summary of the invention
In order to solve the problem, the invention provides a kind of pumping clear-water concrete.
The technical solution used in the present invention is:
A kind of pumping clear-water concrete, is made up of the component of following weight part: cement 290-300 part, water 170-180 part, river sand 840-850 part, 1-2 stone 760-780 part, 0-5 stone 170-190 part, breeze 60-80 part, flyash 60-70 part, gathers and moulds sour admixture 7.0-9.0 part.
A kind of pumping clear-water concrete, is made up of the component of following weight part: cement 295 parts, 173 parts, water, river sand 845 parts, 770 parts, 1-2 stone, 180 parts, 0-5 stone, breeze 70 parts, 65 parts, flyash, gathers and moulds sour admixture 7.8 parts.
Described cement is P.O42.5 cement.
Described breeze is S95 breeze.
Described flyash is first level flour coal ash.
Described pumping clear-water concrete strength grade is C30.
The invention has the beneficial effects as follows: a kind of pumping clear-water concrete provided by the invention, solve transferpump in construction work and, to the transport problem of clear-water concrete, can ensure that structures are to the perception of clear-water concrete and specification of quality simultaneously.
