Abstract:This paper presents the results of an investigation on the effect of blastfurnace slag on the frost resistance and poros-ity of neo-ferrite cement mortar. Neo-ferrite cement is a new type of ferrite cement produced from blastfurnace slag and con-verter slag that is a by-product of the steel industry. In this new cement, the amount of limestone as a raw material in cement production is reduced by approximately 2/3 in comparison with the ordinary portland cement. For the purpose of improving the durability of the cement, freezing and thawing tests were perpormed on prismatic mortars made from neo-ferrite cement incorporating three different amountsofslag by weight. The mortar specimen made from neo-ferritecementincorporating blastfurnaceslag approximately twenty percent (by weight) showed considerably improved resistance to frost action.
