Abstract:
Well-dispersed polymeric microspheres in a mineral powder medium can be used for protecting concrete from cyclic freezing-and-thawing damage. The article presents criteria for assessing the durability of microsphere concrete based on the parameters of the microsphere system in hardened concrete. The key equations for developing the durability criteria are also provided.
