Terrazzo pros and cons? Terrazzo floor construction

Advantages of terrazzo flooring:

1. Good wear resistance, crushed stone is added to the terrazzo floor as aggregate, which has good wear resistance;

2. Economical, suitable for home decoration;

3. Beautiful and generous, play a large space, very popular in the nineties of the last century, once a high-end building materials; After many years of silence, the construction process has improved and returned to the public eye;

Disadvantages of terrazzo floors:

1. It is easy to weathering and aging, loses its original luster, and consumes a lot of waxing;

2. The surface is rough and porous, and if it is used in the factory building, it is easy to hide dirt and dirt, and it is difficult to clean up the oil stain;

3. The corrosion resistance of terrazzo ground is poor, and if it comes into contact with highly corrosive substances, the service life will be greatly reduced.

4. The old terrazzo floor can be renovated with concrete sealing and curing agent to effectively extend its service life.

First, the advantages and disadvantages of terrazzo floor.

After the terrazzo floor is high-brightened, its high brightness reaches more than 70, and it also has the functions of dustproof and anti-slip. The surface of high-gloss terrazzo with high-gloss treatment is hard, and its hardness can reach 6-8 grades. When making high-gloss terrazzo, it can be spliced at will according to the preferences of consumers, and its color can also be customized.

The terrazzo floor is not afraid of heavy dragging, nor is it afraid of heavy truck rolling, and even if there are these conditions, it will not crack, and it will not shrink and deform. The terrazzo floor is resistant to aging, fouling, and difficult to burn, and has no peculiar smell and no pollution.

Terrazzo is made of concrete, so its weight is relatively heavy, the weight of a cement stone is about 5kg, the bigger the bigger the weight, so it is very laborious to carry it too early. Terrazzo flooring cannot be used in highly corrosive locations, which will cause severe corrosion of terrazzo flooring, resulting in a shortened service life. There are many voids in the terrazzo floor, and if there is a stain in water, it will penetrate under the ground, thus contaminating the terrazzo floor, and it is more difficult to clean.

Second, terrazzo ground construction process 1Do the screed.

The screed is made of 1:3 dry hard cement mortar, which is then flattened and then compacted and smoothed.

2.Lattice bar inlay.

After that, it should be plastered with cement to form a figure-eight corner through the long seat, and it must be firmly embedded. In this construction stage, it should be noted that the coating height of the cement slurry should be about three to five millimeters lower than that of the lattice strip, the joints should be tight, and the top surface should be in the same horizontal plane, which requires relatively high construction skills.

3.Plastering the surface layer of stone slurry.

When wiping the mud and stone slurry, it should be proportioned according to the requirements, and the stone slurry surface should be at least swept with hair twice to open the batter, and only after the stone particles are uniform can it be smoothed and compacted with an iron trowel until the slurry is spread. It should be noted here that the ripples must be flattened, and the stones on the top surface of the lattice strip must be cleaned up.

4.Burnish. If the terrazzo ground construction area is large, then a mechanical stone machine should be used for grinding. For small areas or corners, a small portable mill can be used for grinding. For parts where mechanical grinding is not possible, manual grinding is possible.

1. The advantages of terrazzo floor: not afraid of dust, not afraid of cracking, not afraid of heavy vehicle crushing, not afraid of heavy dragging, not easy to shrink and deform, etc., terrazzo flame resistance, aging resistance, fouling resistance, corrosion resistance and other characteristics, in daily cleaning is very simple, and long-term use of gloss will not decrease. 2. Disadvantages of terrazzo floor.

The weight is very heavy, so it is very difficult to handle, and secondly, terrazzo is not waterproof and has strong permeability, so if there are water stains on the ground, it will easily penetrate into the ground and it is difficult to volatilize again.

1. Heavy weight: terrazzo is a kind of concrete product, the weight of a terrazzo floor is about 5kg, the larger the weight of the terrazzo floor, the heavier it will be, making it very time-consuming and laborious in the process of handling.

2. Easy to weather, easy to corrode, short life: terrazzo ground has poor corrosion resistance, if it is used in highly corrosive places, or if it is used to clean the terrazzo floor with a highly corrosive detergent, it will cause very serious corrosion of the floor, and the service life of the terrazzo floor will be greatly reduced, and it may only be able to use it for more than ten years.

3. It is not waterproof and has strong permeability. There are a lot of voids in the middle of the terrazzo floor, these voids can not only hide the ash layer but also pass through the water, if there are water stains on the ground, it will easily penetrate below the ground, and by the way, the stains on the ground will also be brought down, polluting the terrazzo floor, and it will be very difficult to clean.
