Abstract

An admixture that reduces efflorescence in concretes and mortars is disclosed. The admixture consists of a mixture of granulated blast furnace slag, finely divided fly ash, finely divided flour, a long chain fatty acid and an anionic dispersant. The admixture is typically used at 0.5 to 5% w/w cement or cementitious binding material in a concrete or mortar.
