Durability Evaluation of Frost-Resistant Concrete Modified with Additives

Abstract:

The article presents the influence of the addition of microsilica, finely divided sodium bentonite and air-entraining admixture for concrete frost-resistance and characteristics of examined concrete pores. Examination of frost-resistance was conducted for 150 cycles of freezing and thawing. For selected series of concrete the examination of the porosity structure of concrete composites was conducted with the use of a device for automatic image analysis and computer program Lucia Concrete. What is more, there was made a designation of: consistency of concrete mix, air content in concrete mix, compression strength, water penetration depth and concrete absorbability.
