Evaluation of carbonation resistance of paint coated concrete for buildings
文摘

Carbonation depth of C35 standard cured concrete is 56% smaller than that of C25.

Accelerate curing increases carbonation depth of C25 concrete by 61%.

Paint coating can reduce 28-day carbonation depth of concrete by 46% at least.

Carbonation suppression ratio varies with exposure time and quality of substrate.

Exterior paint coating has a longer blockage time and a smaller carbonation rate.
