POLYMER MODIFIED CONCRETE. CHANGE OF MECHANICAL PROPERTIES OF PCC DUE TO LONG TIME EXPOSURE CONDITIONS

Polymer modified concretes have been subjected to various climatic conditions over 7 years to find out differences in their hardening characteristics and in particular the influence of temperature and moisture on the development of strength and elasticity. Generally the resistance of concrete to longtime exposure conditions is clearly improved by the investigated dispersions, regardless of their generic type. This could be recognized more by the change of the dynamic modulus than by the compression test, that may pretend sound materials, while the dynamic modulus points out structure defects. To compare dynamic moduli, the content of moisture has to be taken into account. A special correlation between moisture content, density and the change of dynamic modulus of elasticity has been given.
