Concrete Curing

Evaporation Retarder

þ       Confilm®

Confilm evaporation reducing admixture helps produce high quality concrete flatwork and reduces surface moisture evaporation. Because Confilm admixture retards evaporation, it is especially effective in combating rapid drying conditions including, high concrete and/or ambient temperatures, low humidity, high winds, direct sunlight or work in heated interiors during cold weather, etc.

Features

Reduced surface moisture evaporation about 80% in wind and about 40% in sunlight

Eliminated or reduced crusting, stickiness and underlying sponginess which often cause unevenness and poor surface texture

Reduced and, in many instances, eliminated plastic shrinkage cracking and wind crusting of flatwork surfaces

Supplement the recommended practices for hot weather concreting

Safeguard against the ill effects of evaporation

Allowed lower slump and lower unit water content in concrete used for flatwork

Facilitate use of air-entrained concrete, required for durability and workability, in situations where air-entrainment might be avoided for fear that it would increase concrete's susceptibility to crusting and stickiness under drying conditions

Benefits

Virtually eliminated need to add extra mixing water to compensate for rapid evaporation during finishing

Time and money saved by increasing the amount of surface handled per finisher even under rapid drying conditions

Timing of the operations is less critical, thus reducing overall cost
