Fair-faced concrete and fair-faced concrete building construction process

Abstract

The invention relates to fair-faced concrete and a fair-faced concrete building construction process, and belongs to the technical field of concrete. The fair-faced concrete comprises the following components in parts by weight: 370-390 parts of Portland cement; 85-95 parts of fly ash; 870-890 parts of coarse aggregate; 890-898 parts of washed sand; 150-160 parts of water; 11-11.6 parts of an additive; and 9.5-10.5 parts of silicon. The fair-faced concrete prepared from the components in parts by weight is high in strength and good in surface forming effect. The fair-faced concrete building construction technology comprises the following steps of a, pouring blinding concrete; b, binding wall column steel bars on the blinding concrete; c, erecting a formwork support; d, installing a wall column formwork; e, binding beam and plate steel bars; and f, pouring the fair-faced concrete. Through the specific steps, a fair-faced concrete building high in strength and good in surface forming effect can be built.

Description

Technical field [0001] The present invention relates to a construction process for water concrete and water concrete construction, which belongs to the field of concrete. Background technique [0002] Water-saving concrete is a special concrete in existing concrete. It is a concrete that directly utilizes concrete, with natural texture or only brushless protective coating, as a concrete of the finished effect, which is neat, color natural, line It meets the design rhythm as a goal, which can meet the requirements of various architectural styles, and there is an excellent decorative effect, so it is also known as decorative concrete. The water concrete uses a cast-shaped, do not do any outer decoration, directly utilizing the natural surface effect of concrete as a finger, can save the traditional plastering, stickers, etc., different from ordinary concrete, surface requirements of water concrete It is smooth and smooth, and the color is uniform, distinguished, no damage and pollu...

AI Technical Summary

Problems solved by technology

The existing fair-faced concrete mix ratios are all carried out with the ordinary concrete mix ratio design method (such as "JGJ 55-2011 Ordinary Concrete Mix Ratio Design Regulations"), and the amount of various ingredients is adjusted as appropriate, resulting in the surface of the poured clear-water concrete Rough and uneven everywhere, large color difference, large pores and gaps and uneven distribution, or while obtaining surface quality, the strength of concrete cannot be guaranteed, it is difficult to meet the design requirements of fair-faced concrete, and it is impossible to directly use cast-in-place concrete The natural surface effect is used as a finish, and traditional plastering, veneering and other whitewashing processes are still required
