Abstract

Concrete bricks and hollow concrete block products manufactured using ordinary portland cement react with salt and carbon dioxide absorbed from the soil and atmosphere in the use environment, causing contamination such as efflorescence. This is due to the reaction between calcium hydroxide, a cement hydration product, and carbon dioxide, producing and eluting calcium carbonate. This study was a preliminary study to compare and evaluate the reduction of efflorescence in concrete bricks and hollow concrete block products manufactured using carbon dioxide reaction hardening cement. The purpose was to evaluate the efflorescence occurrence in products using ordinary Portland cement.
