Abstract:Polymer-modified concretes have been subjected to various climate conditions over seven 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 long-time exposure conditions is clearly improved by the investigated dispersions, regardless of their generic types. This could be recognized more by the change in the dynamic modulus than by the compression test, which may pretend sound materials while the dynamic modulus points out structural 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.
