Ice formation in pores in polymer modified concrete: I. The influence of the admixture on the water to ice transition

Agnieszka Klemm, Piotr Klemm

Research output: Contribution to journalArticle

Abstract

This paper reports results from a larger study on the influence of two admixtures (methyl hydroxy ethyl celullose, MHEC and polyvinyl acetate, PVA) on properties of water contained in pores and capillaries of cementitious materials subjected to freezing and thawing cycles. The Differential Scanning Calorimetry technique has been found to be particularly useful in evaluating the amount of heat that is involved as material undergoes either an endothermic or an exothermic transition. An attempt has been made to explain some aspects of phase transition based on the Everett and Hynes model. Test results have shown that the lowest values of ice concentration were recorded for composites which had the lowest MHEC contents and finer microstructure.
