Early-Age Free Shrinkage of Mortars with Different Dosages of EVA Redispersible Powder
The plastic free shrinkage evolutions of mortars in the presence of different dosages of redispersible Ethylene-vinyl acetate (EVA) copolymer powder were measured using the laser sensor at acceleration dry for 6 hours. The effects of temperature, relative humidity, air contents and water evaporation of mortars on the plastic free shrinkage were observed. The plastic free shrinkage of mortars declines firstly and then rise under the increasing dosage of EVA powder in range of 1%∼10% mass of cement in mortars, the plastic free shrinkage of mortars with 10% EVA powder was almost closed to that of plain cement mortars. The EVA powder facilitates a decrease in plastic free shrinkage of mortars. The linear regression equation between the plastic free shrinkage and its effect factors was set up, and analysis of variance was used to analyze the significant of air content and water evaporation.
