Problems solved by technology

However, due to the rough surface and poor flatness of the currently used formwork, many troubles have been left for the formed concrete. For example, the surface needs to be plastered and leveled again, which is not only complicated and time-consuming, but also increases additional costs.

specific Embodiment 1

[0045] Specific embodiment 1: select the polycarboxylate superplasticizer that adds 1.2% (by cement weight) for use in ordinary portland cement, water-cement ratio 0.31, be viscous after mixing and the clean slurry with good fluidity, use float glass Or calcite crystal surface is used as the substrate, after pouring the slurry, it is vibrated on the vibration table to shape, and it is cured for 2 days, and the mirror surface cement slurry that can be seen by people can be prepared, and there are a few fine cracks on the surface.

specific Embodiment 2

[0046] Specific embodiment 2: select common Portland cement for use, add the polycarboxylate superplasticizer of 2.5% (by cement weight), add 1.5% sodium sulfate early-strength agent, water-cement ratio 0.32, pour into after mixing evenly Flat glass is used as the substrate, molded on a vibrating table, and cured for 3 days to prepare a clear mirror cement paste with slight cracks on the surface.

specific Embodiment 3

[0047] Specific embodiment 3: select ordinary Portland cement, water-cement ratio 0.35, add the polyester fiber of 1.5% volume ratio, stir evenly to make fiber reinforced net slurry, make substrate with plate glass, or make substrate with covered PVC plank , vibrated on a shaking table to shape, and keep in good health for 2 days, and can prepare a clear mirror cement slurry with basically no cracks on the surface.

Abstract

The present invention provides one kind of very smooth mirror surface cement-base material produced with material of water to cement ratio of 0.25-0.45, aggregate/cement weight ratio of 0-5, admixture/cement weight ratio of 0-10 %, and reinforcing fiber material accounting for 0-5 %. During its production, concrete, mortar and cement slurry is first poured onto smooth base plate, and after wet curing, the base plate is stripped off. The very smooth mirror surface cement-base material has smooth surface, mirror effect and homogeneous color, and possesses simple production process, low cost and excellent decoration effect. It may be used as floor board, outer wall tile, wall plate, etc.

Description

technical field [0001] The invention relates to the field of materials, in particular to an ultra-flat mirror surface cement-based material with a decorative effect and a preparation method thereof. Background technique [0002] Since the application of cement, in people's impression, cement concrete is always rough and dull, even if it is made into clear water mirror concrete, it still cannot get rid of monotony and roughness. If the surface finish of cement-based materials can be improved, the surface texture of cement-based materials can be better controlled, and the cement-based materials can be endowed with richer and more delicate decorative effects, which can better reflect the inherent texture and "natural color" of concrete. ". [0003] At present, the clear water mirror concrete is generally formed by formwork, but no matter which formwork is used, as long as the formwork has high enough strength and rigidity, the surface smoothness of the formwork directly determ...
