Polymer concrete rapid repairing materials to 30 s
Many cement pavement diseases, such as not timely repair will soon become incurable diseases, and these diseases, there is no ideal solution, the basic diseases such as development is the way to a certain extent to dig, lead to waste a lot of precious materials, at the same time, the long closed to increase the cost of transportation is becoming more and more valued.
Polymer concrete rapid repairing materials - 30 s is my company independent research and development of a new type of airport pavement, road, bridge rapid repairing materials, the material has obtained national invention patent, patent number: 3387501. Polymer concrete rapid repairing materials - 30 s is made up of special cement, imported powder and special additive and promoter, high strength of fiber and selection of aggregate composition, its main characteristic is the premise of ensuring we'll have enough construction time, since water 1 to 2 hours, more than 2 hours to 25 mpa compressive strength, can reach the requirement of rapid opening traffic.

一、产品特性:
Product features:
1, high early strength, post strength to fail;
2, shrinkage, expansion, and the original concrete component adhesive ability;
3, excellent durability and resistance to fatigue loading ability;
4, in the environmental temperature 5 ℃ above the normal construction, and 90 minutes to achieve the requirement of the open to traffic;
5, the suitable operation time, high liquidity, self-compacting, construction is convenient.
6, have strong ability of compressive strength and bonding strength of disease in place timely repair without closed traffic for a long time.
二、用途及使用范围
Second, the purpose and use scope
The product is widely used in highway, high-speed railway, airport runway, Bridges, municipal, parks and other important rapid repair of concrete pavement, cement road surface explicit, pits, honeycomb, peeling, freezing and thawing, broken horn, so concrete pavement diseases to timely make emergency repair, etc.
Three, main technical index
Four advantages,
(1) rapid repairing pavement can open traffic in a short time.
(2) to avoid large area in plate, reduce engineering cost.
(3) the construction craft simple, add water.
(4) the construction without using large machinery, little influence on traffic safety.
Five, the construction process
1, the surface treatment: find out the reason of this damage will be broken and loose clinker was removed, the new interface fully wetting with water.
2. Construction:
Welcome all enterprises and institutions to inquire and negotiate, we will serve you wholeheartedly!
