Admixtures for Concrete - Improvement of Properties: by E. Vazques

By E. Vazques

Chemical admixtures are used to change the houses and behavior of unpolluted and hardened concrete. they allow extra fiscal building and the fulfillment of designated houses reminiscent of excessive energy or sturdiness. This publication offers new study info from a global RILEM Symposium on six major subject matters: workability, atmosphere, power, toughness, different houses and know-how.
