Methods for rating concrete waterproofing materials

In an attempt to develop reliable test methods for evaluating the effectiveness of concrete waterproofers, it was found that a combination of saturated and unsaturated permeability tests is necessary, the latter covering more than one humidity condition.Dans un effort en vue de mettre au point des m\ue9thodes d?essai fiables pour l?\ue9valuation de l?efficacit\ue9 des syst\ue8mes d?hydrofugeage du b\ue9ton, il a \ue9t\ue9 d\ue9couvert qu?il \ue9tait n\ue9cessaire de r\ue9aliser une combinaison d?essais de perm\ue9abilit\ue9 satur\ue9s et non satur\ue9s, ces derniers couvrant plus qu?une seule condition d?humidit\ue9.Peer reviewed: NoNRC publication: Ye
