Embodiment 1

[0043] Such as figure 1 As shown, the concrete terrazzo floor, the method includes the following steps:

[0044] S1: Construction preparation, the sand and gravel cushion under the first floor is compacted with a road roller, and the compaction coefficient is greater than 0.96; remove all unnecessary sundries and facilities on the construction site, keep the construction surface clean and tidy, and have no cross construction;

[0045] S2: Concrete pouring, the concrete grade is not lower than C30, clean river sand is used, no machine-made sand and surface sand are added, no fly ash and mineral powder are added, and the on-site slump is between 140-160 mm;

[0046] S3: Preliminary leveling and closing. After S2, the concrete surface has been basically leveled. Use a wooden trowel and a scraper to smooth the footprints on the surface and the unevenness of the vibration, and use a wooden trowel to initially smooth it;

[0047] S4: The initial setting of the concrete, the initial...

Embodiment 2

[0070] The difference from Example 1 is that the Li-based curing agent is configured during construction, and 1.5 g of magnesium aluminosilicate, 3 g of phosphorus fluorosilicate, 1.5 g of magnesium aluminum phosphate, and 3 g of zinc fluorosilicate are weighed according to the formula. Hydrofluoric acid 0.5g, sodium silicate 0.3g, mix the weighed components, add 200g water at room temperature and stir at a constant speed for 20 minutes, the prepared new Li-based curing agent solution is uniform, stable and transparent, ready for use.

Abstract

The invention relates to a concrete millstone terrace. The concrete millstone terrace comprises the steps of (S1) construction preparation, (S2) concrete casting, (S3) primary ground leveling, (S4) concrete primary solidification, (S5) hard leveling, pulp extraction and trimming, (S6) stone spreading and polishing, (S7) leveling, rolling, trimming and polishing, (S8) slit cutting and curing, (S9)primary rough grinding, (S10) grouting, (S11) secondary fine grinding, (S12) Li base curing, (S13) ternary finish grinding, (S14) Guard protective agent brushing and (S15) 3000-mesh polishing for thefourth time. The concrete millstone terrace is high in scratch resistance, high in strength and not easy to generate hollows and cracks, and meanwhile, greatly reduces the terrace cost.

Description

technical field [0001] The invention belongs to the technical field of concrete terrazzo floor construction technology, and in particular relates to a concrete terrazzo floor. Background technique [0002] At present, domestic parking lots, exhibition halls and other large public buildings and high-end private residential floors are mostly decorated with terrazzo and artificial marble. These floor materials have gaps, which are easy to accumulate dirt, and it is difficult to design patterns. Terrazzo Including epoxy terrazzo and inorganic terrazzo, but the epoxy terrazzo in the current market has disadvantages such as low wear resistance, low scratch resistance, and easy aging; inorganic terrazzo and traditional terrazzo are prone to hollowing, cracking and cost higher disadvantages. [0003] In the prior art, the terrazzo technical solutions are as follows: [0004] Chinese patent application 201510488455.7 discloses an inorganic crystal terrazzo integrated floor and its ...
