new controllable absorbing concrete curing film for highways

Superior product performance:

1.Efficient saving water

The concrete pavement only needs to be watered one time when it has been paved,and there is no need to water the cement stabilized macadam base course during the curing period,it can save curing water by more than than 95%;

2.Lasting Moisturizing

The curing surface always keeps moist during the curing period;

3.Thermal Insulation

The temperature inside the curing film is 4-10℃ higher than outside under the action of hydration heat;

4.Beautifying Construction Site

It has merits as follows:a tidy workplace,no floating sand,a uniform color,and the pavement presents caesious after the curing period;

5.Nontoxic and Harmless

This product is friendly to environment because its main material is biodegradable;

6.Preventing Mico-cracks

The double performance,both thermal insulation and moisture retention,can effectively reduce the generation of mico-cracks;

7.Improve concrete strength

The double performance,both thermal insulation and moisture retention,can effectively improve the concrete strength;

8.Improve carbonizing-resistant capability

The double performance,both thermal insulation and moisture retention,can effectively improve the carbonizing-resistant capability;

9.Improving Abrasion Resistance

The abrasion value is only one-tenth of relevant the national standard.
