Sikagard-30 ER Evaporation Reducer for Fresh Concrete 1 Gallon Jug

Sikagard-30 ER Evaporation Reducer for Fresh Concrete 1 Gallon Jug

Sikagard-30 ER reduces surface moisture evaporation from freshly placed concrete, especially in rapid-drying conditions, such as high concrete surface or ambient temperatures, low humidity, high winds, direct sunlight, or work in heated interiors during cold weather.

Recommended Uses:

• Concrete surfaces where the evaporation rate exceeds the bleed rate
• Air-entrained and non-air-entrained concrete
• Silica-fume concrete
• Concrete containing fly ash

Features & Benefits:

• Does not affect concrete strength (early and ultimate), abrasion resistance, and durability
• Reduces or eliminates crusting, stickiness, and underlying sponginess resulting in a consistent surface
• Reduces surface moisture evaporation approximately 80% in wind and approximately 40% in sunlight to reduce plastic shrinkage cracking and wind crusting
• Allows reduced slump and water content in concrete to facilitate proper hydration of high-strength mixes
• Facilitates the use of air-entrained concrete to make air entrainment possible in rapid-drying conditions
• Prolongs surface plasticity for longer working time in hot, dry, or windy conditions
