Influence of temperature on the properties of non-air-entrained and air-entrained cement mortars modified with different plasticisers and superplasticisers types

摘要

The paper presents the results of the research on the impact of low and high temperature on the air content and consistency of non-airentrained and air-entrained and plasticized or superplasticized mortars according to PN-EN 480-1, which were made with CEM I cement. In case of the mortar with CEM I, various types of plasticizers and superplasticizers as well as aeration admixtures differing in chemical base were used. The analysis of the results of the research indicates that the effect of temperature influences the consistency and air-content of the mortar depending on the result of the type of plasticizing and superplasticizing admixture.
