The formwork requirements for the construction of fair-faced concrete precast components are very strict.

The main business of Concrete Precast Component Co., Ltd. includes concrete components, cement components, concrete products, roadbed, water conservancy, tunnels, roads and bridges, etc.

Detailed introduction to the supply of precast concrete components.

The origin of raw materials must be consistent, and the cement used should be from the same batch of precast concrete component manufacturers as much as possible; the color and particle gradation of sand and stone should be uniform.

The formwork requirements for fair-faced concrete construction are very strict and need to be designed and customized according to the building. Most of the formwork used is disposable and the cost is high. It is better to use exit formwork for corners, beam and column joints and other important parts;

The formwork must have sufficient stiffness, and no deformation is allowed under the action of concrete lateral pressure to ensure uniform geometric dimensions and uniform cross-section of the structure to prevent slurry loss; there are also very high requirements for the materials of the formwork. The surface must be flat and bright, with high strength, corrosion resistance, and certain water absorption; for the joints of the formwork and the bolts that fix the formwork, the joints are required to be tight, and sealing strips must be added to prevent slurry from running.

It can exert excellent water-stopping performance in a wide temperature range and has excellent weather resistance.

Excellent water resistance, chemical resistance, and durability. It does not contain harmful substances, has no deep expansion precipitates, and does not pollute the environment.

Sealing strips of any shape can be made according to user needs, and can be combined with general rubber to make composite waterproof materials.

When the joints or construction joints are displaced, causing the gap to exceed the elastic range of the material, ordinary rubber water-stopping materials lose their water-stopping effect, while this product can also stop water by absorbing water and expanding.

Using water-swellable rubber as a leak-proof sealing and water-stopping material not only saves usage, but also eliminates the characteristics of elastic fatigue caused by excessive compression of general elastic materials, making the waterproofing effect more reliable, with good water resistance, chemical resistance and aging resistance.
