Concrete construction method and mirror-surface concrete pier column

Abstract

Disclosed is a concrete construction method. The method comprises the following steps that the inner surface of a steel template is uniformly coated and brushed with a mould releasing agent, and standing is conducted till the steel template is completely dried; cement, fly ash, fine aggregate, coarse aggregate, water reducing agents and water are uniformly mixed, and the slump of the concrete after mixing is 160-200 mm; a steel reinforcement cage model inner framework is built, the completely-dried steel template is assembled on the outer periphery of the steel reinforcement cage inner framework to form a model outer framework; the uniformly-mixed concrete is poured into the outer framework, a mode of combining an insertion-type vibrating rod and a flat-plate vibrator is adopted for vibrating in the pouring process till slurry bleeding begins to occur on the surface of the concrete, and no obvious bubbles are generated; curing is conducted after concrete pouring is completed, and afterstanding is conducted for at least 100 h, the steel template is disassembled by block. The invention further provides a mirror-surface concrete pier column. The concrete prepared by means of the construction method can achieve a good mirror surface effect, the surface of the concrete is smooth, bright and clean, the color and luster are uniform, and no bubbles occur; the appearance quality of theconcrete is improved, and the appearance attractiveness of the concrete is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a concrete construction method and a mirror concrete pier column. Background technique [0002] As a new type of architectural form, fair-faced concrete forms its unique aesthetic feeling with its fine and delicate texture, dense and nearly homogeneous texture, and is accepted by more and more architects. Fair-faced concrete has produced good economic and social benefits. The construction of fair-faced concrete saves the traditional wet work such as plastering, reduces the process, shortens the construction period, and saves machinery costs, labor costs and management costs. In addition, the fair-faced concrete slab has good flatness, which can save the construction of the leveling layer, which not only improves the quality, but also reduces the construction cost and increases the usable space, so it has good economic benefits. Today, as more and more attention is ...
