Background
The finished mirror-finished concrete member has the mirror-finished effect of marble, granite and other block materials on the surface, and is applied and implemented in industrial buildings such as power plants, coal mines, industrial plants and the like in China in recent years. The mirror surface concrete has the following characteristics:
1. the mirror surface concrete can achieve the mirror surface decoration effect of marble, granite and other bulk materials without secondary decoration, and the decoration materials such as paint, veneer plates and the like are omitted.
2. The mirror concrete structure is not plastered or sprayed, thereby reducing a large amount of construction waste and being beneficial to environmental protection.
3. The mirror concrete avoids the hidden quality troubles of plastering cracking, hollowing and even dropping, and eliminates a plurality of common quality problems.
However, the existing mirror concrete construction technology is uneven, so that the engineering effect after actual construction cannot reach or even cannot reach the effect. Therefore, a more reasonable technical scheme needs to be provided to solve the technical problems in the prior art.
Disclosure of Invention

In order to achieve the purpose, the invention specifically adopts the technical scheme that:
a construction method of mirror concrete of a wood plastic-coated flat template comprises the following steps:
arranging templates, assembling and manufacturing a wall template, a top template, a frame column template and a beam template by using wood plastic-coated flat templates, and respectively placing and fixing along an installation standard;
pouring concrete, namely performing layered pouring and vibrating in layers, or performing one-time pouring;
curing the concrete, namely covering the concrete by using a film after the concrete is poured and the surface is calendered, and keeping the original blended water in the concrete from evaporating to form natural vacuum curing;
concrete repair, namely performing construction repair on the defective part on the surface of the concrete finished product so as to achieve the surface effect consistent with that of mirror concrete;
and (4) removing the templates, and removing the templates from the lower layer upwards in sequence.
According to the construction method disclosed by the invention, after the smooth formwork is arranged, concrete is selected and blended, and pouring, maintenance and repair are carried out, so that the construction of the mirror concrete is finally realized, and the set requirements on strength and surface degree are met.
Furthermore, in the construction process, if high-grade cement is used for preparing low-grade concrete, the cement consumption is too small, the W/C is increased, and the surface of the concrete cannot achieve the mirror effect due to sand generation in the use process; if the high-grade concrete is prepared by using the low-grade cement, the cement consumption is increased, the shrinkage deformation of the concrete is increased, and the micro-cracks on the surface of the concrete are directly generated. Therefore, the concrete is optimized when being prepared, and the following specific feasible schemes are listed: the concrete is prepared by adopting Portland cement with 0.4-0.5 percent of alkali content, coarse aggregate with the maximum grain diameter not more than 40mm and fine aggregate with the grain diameter less than 0.15mm accounting for 6-8 percent of the total weight of the aggregate.
When the concrete surface treatment agent is arranged, the cement consumption can be saved due to the arrangement of the coarse aggregate, the concrete can be more compact due to the arrangement of the fine aggregate, capillary holes on the surface of the concrete can be blocked, and the surface degree of the concrete is improved.
Still further, as a preferable mode, the selection of the coarse aggregate is not uniquely determined, and the following specifically possible modes are exemplified here: the coarse aggregate is crushed stone with a continuous gradation of 5-31.5 mm in particle size.
Furthermore, the amount of the fly ash added into the concrete can save the cement consumption, but the excessive addition of the fly ash can cause the shortage of the cement content and the separation of the fly ash and the cement in the concrete vibrating process, the fly ash is suspended on the upper part of the concrete, so that the upper part of the concrete member is matt, and the mirror effect is directly influenced, therefore, the addition amount of the fly ash is strictly controlled. Therefore, the following embodiments are specifically possible: and replacing part of cement with fly ash, wherein the cement replaced with fly ash accounts for 5-8% of the weight of the cement.
Furthermore, under the condition that the cement consumption is not changed, the water consumption is increased, and the bubble holes on the surface of the formed concrete member are increased, so that on the premise of ensuring the concrete strength, the workability and the flowability of the concrete must be solved if the unit water consumption is reduced, and the two problems are solved by the following steps: adding a certain amount of high-efficiency water reducing agent into the concrete and increasing the sand rate to increase the slump of the concrete.
The theoretical basis for solving the workability of concrete is as follows: the cement dosage must be adjusted when the sand rate is increased; and adding a water reducing agent to ensure that the water-cement ratio is unchanged.
The theoretical basis for solving the fluidity of concrete is as follows: the water consumption is increased or a water reducing agent is added to increase the slump of the concrete. The water consumption is increased, and the cement consumption is required to be adjusted to ensure that the water-cement ratio is not changed, but the water-cement ratio is not economical; and adding a water reducing agent, and keeping the water-cement ratio unchanged.
Therefore, a specific feasible technical scheme is proposed here: in the process of preparing concrete, a water reducing agent with the air content less than 4% is added to solve a series of problems of slow setting, slump loss prevention, reinforcement and the like.
Furthermore, in the concrete pouring process, when the concrete is poured in layers, the laying thickness of each layer of concrete is less than or equal to 40cm, and after one layer of concrete is laid, a transition layer with the thickness of 5-10 cm is filled on the joint surface of the layer of concrete and the subsequent concrete pouring.
And further, after the concrete pouring is finished, the upper openings of the outer formworks are aligned, so that the joint lines of the concrete are smooth and straight, and the concrete on the outer side is higher than the concrete on the inner side.
And further, the concrete curing time is more than or equal to seven days.
Further, the concrete repairing method comprises the following steps:
chiseling the defect part to be repaired, cleaning and brushing cement paste, wherein the mass ratio of 1: 2, repairing and drying cement mortar;
washing the deep surface for 3-5 mm and cleaning the surface, wherein Portland cement with alkali content of 0.4-0.5% and white cement are adopted according to the weight ratio of 1: 1.5, adding a building glue solution to prepare a cement paste to construct the surface of the defect part, flattening, scraping, and naturally drying;
carrying out dry grinding and rough flattening on the surface, winding and maintaining by using a film, and carrying out surface finish grinding after the preset strength requirement is met; and (4) fully brushing 1-2 times of water glass after the requirement of the set flatness is met, and performing fine grinding after 24 hours.
Furthermore, in the whole construction process, the thickness of the wood plastic-coated flat template is not less than 15 mm. In the later construction period, the concrete must reach enough strength when the form is removed, and the lower-layer member formwork is removed after the upper-layer member concrete is poured to prevent the lower-layer member from being polluted.
Compared with the prior art, the invention has the beneficial effects that:
according to the construction method disclosed by the invention, the appearance impression quality of the beam and column concrete members is improved through the splicing design of the beam and column templates, the design of the concrete proportion and the improvement of the construction technology; the material is saved, the self weight of the building is reduced, and the natural and beautiful effect is added to the building; not only the construction period is shortened, but also the construction cost is reduced; the working procedures of decoration plastering, spraying and the like are saved, a large amount of construction waste is reduced, and the environment protection is facilitated.
