Inner Mongolia Xika High strength Grouting Material Cost

curing

1) Within 30 minutes after grouting, curing agent shall be sprayed immediately or covered with plastic film and covered with rock wool quilt for curing, or water shall be sprayed immediately after final setting of grouting layer for moisturizing curing.

2) During winter construction, the curing measures shall also comply with the relevant provisions of the current Code for Acceptance of Construction of Reinforced Concrete Works (GB50204).

3) Curing time and formwork removal schedule under different temperature conditions

Daily low temperature (℃) Formwork removal time (h) Curing time (d)

Concrete structure transformation and reinforcement grouting:

(1) The concrete surface contacted by cement-based grouting materials shall be fully chiseled.

(2) For the repair of concrete structure defects, the loose concrete shall be removed and exposed to the reinforcement, and the edge of the repair area shall be cut into a vertical shape.

⑶ Before grouting, all crushed stones, dust or other sundries shall be removed, and the surface of base concrete shall be wetted.

⑷ Pour evenly mixed grouting materials into the formwork and knock the formwork properly.

(5) When the thickness of the grouting layer is greater than 150mm, relevant measures shall be taken to prevent temperature cracks.

Development trend of Sika high strength grouting material
At present, high-strength grouting materials should be In addition to making more efforts to protect and treat water quality and the surrounding environment, efforts should also be made to study and solve difficult and new problems. Compound technology will be an effective way to improve and meet various functions.
1. Function compounding. It has the advantages of reliable quality, low cost, short construction period and convenient use. The stress condition of equipment base is fundamentally changed, so that it can bear all loads of equipment evenly, so as to meet the installation requirements of various machinery and electrical equipment (heavy equipment grinder). It is an ideal grouting material in the era of mat free installation.
2. The anti freezing and anti freezing properties of grouting materials shall be strengthened; Solve the problem of construction in winter, strive to make a breakthrough in the base material composite technology and the mix proportion of related aggregates, and solve the problem in warm construction.
3. The modification function of the base material is compounded. The existing base material is modified in some way and compounded with the function. The selection of aggregate shall be based on strong grouting material, cement as auxiliary material, supplemented by high flow state, micro expansion, anti segregation and other substances, so as to achieve dual functions.
