Title: Furthur Study of Particulate Admixtures for Enhanced Freeze-Thaw Resistance of Concrete

Abstract:Investigation of a previously developed method of increasing the resistance of concrete to freezing and thawing by the addition of porous particulates of specified pore structure is continued. Vermiculite and two grades of pumice and perlite were tested for suitability as additives, and their performance compared with that of a previously examined brick. Of the mineral tested, vermiculite, one pumice, and one perlite provide excellent resistance to freezing and thawing of cement pastes (water-cement ratios = 0.48 and 0.42), mortar (water-cement ratio = 0.75), and concrete (water-cement ratio = 0.63).
