Terrazzo is a product made by mixing gravel, glass, quartz stone and other aggregates into a cement binder to produce a coagulated product and then grinding and polishing the surface. Terrazzo is widely used due to its unique advantages, such as its low cost, free color palette and easy construction. Next, Xiaobian gave everyone a detailed introduction of the construction process of terrazzo floors and terrazzo floors .

First, what is terrazzo floor

Terrazzo (also known as grinding stone) is a mixture of gravel, glass, quartz stone and other aggregates cement mixed materials made of concrete products after the surface grinding, polishing products. The terrazzo made of cement bonding material is called inorganic grinding stone, the terrazzo made of epoxy bonding material is also called epoxy grinding stone or organic grinding stone, and the terrazzo is divided into terrazzo and prefabricated plate terrazzo floor according to the construction process. .

  

Second, the advantages of terrazzo

(1) High-grade terrazzo (also known as commercial terrazzo) After the surface highlights, the high-brightness reaches over 70-90 degrees, and the dust-proof and anti-slip can reach the marble quality.

(2) Wear resistance terrazzo, surface hardness can reach 6-8.

(3) Prefabricated or prefabricated terrazzo, can be arbitrarily spliced ​​color, color can be customized.

(4) The new terrazzo is not cracked, is not afraid of heavy-duty rolling, is not afraid of heavy objects dragging, does not shrink deformation.

(5) No dust and high cleanliness; The cleanliness meets the requirements of high cleanliness such as pharmaceuticals and chip manufacturing.

(6) Inorganic terrazzo is non-combustible, non-pyrogenic, anti-aging, anti-fouling, anti-corrosion, no odor, and no pollution.

(7) bright and clean color, if you need to improve the bright hit the floor wax or crystal, (does not affect its anti-static properties), hardened wear water mill stone, do not need to fight wax can also maintain long-term Korea.

(8) The existing terrazzo decorative grid strips are horizontal and vertical, no gaps are required between the grid strips, the connection is dense, and the overall appearance is good; commercial terrazzo can be freely designed to achieve beautiful decorative effects.

(9) The building performance and mechanical performance are the same as the high-quality terrazzo floor used in various buildings. It conforms to the requirements of national standard GB50209-2002 and complies with JC507-1993 standard requirements for building terrazzo products.

Third, terrazzo floor construction process

1. Preliminary preparations are mainly the preparation of construction materials and the clear definition of operating conditions.

2, clear process flow:

Treating, wetting the base layer → playing ash cake, making ribs → wiping the leveling layer → curing → inlaying sub-grid bars → laying cement grout pulp → curing test grinding → grinding the first pass and replenishing the slurry → grinding the second pass and replenishing the slurry → Grind the third pass and cure → Polish with oxalic acid wax

3, to operate

(1) Do a leveling layer

Leveling layer with 1:3 dry cement mortar, the mortar first flattened, and then press the screed with a pressure bar, then with a wooden trowel leveling compaction.

(2) Stripe mosaic

With pure grout in the lower part of the grid strips, the splayed corners are embedded in the long seats and the copper wires are buried well. The smearing height of the pure grout should be 3 to 5 mm, which is lower than the grid height. The grid should be inlaid firmly, the joints are tight, the top surface is on the same plane, and the pass line is to check the flatness and straightness.

(3) plaster stone surface

Mud grouting must be strictly measured according to the mix ratio. The groats of the pebbles must be smashed and opened by at least two times with wool to check the size of the granules, and then the iron trowels should be used to level and compact them until they reach the fulcrum. It is required that the corrugations be flattened and that the stones on the top of the dividing strips should be removed.

(4) Polishing

Large-area construction should be ground with a mechanical grindstone mill. Small areas and corners can be ground using a small portable mill. When the local area cannot be ground mechanically, it can be ground manually.

Editor's summary: The construction process of terrazzo floor and terrazzo floor is introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
