Can the concrete surface be covered with plastic film in winter construction?
When the temperature of the concrete environment, can cause the concrete curing period in icy conditions, should also be covered with grass, tarpaulin insulation. Prevent concrete from freezing and thawing.
The advantage of covering plastic films is that water conservation concrete. The need for this chemical reaction. The plastic film prevents water from evaporating while causing heat dissipation and achieves the effect of heat preservation.
The hardening process of concrete is the chemical reaction of water. Concrete is called concrete when hardened. Concrete releases heat in chemical reactions, and heat accelerates the evaporation of water in concrete. Therefore, concrete pouring must ensure that the moisture content of concrete mixture can meet the needs of this chemical reaction.
