Determination of Equivalent Thickness of Concrete Masonry Units

The equivalent thickness of a hollow masonry unit is usually defined as the product of the over-all thickness of a unit and ratio of its net volume to its gross volume. The over-all thickness and gross volume can be determined from simple measurements. Determing the net volume, however, may often present some difficultiesL'\ue9paisseur \ue9quivalente d'une unit\ue9 de ma\ue7onnerie creuse correspond g\ue9n\ue9ralement au produit de l'\ue9paisseur totale et au ratio de son volume net par rapport \ue0 son volume brut. De simples mesures permettent de d\ue9terminer l'\ue9paisseur totale et le volume brut, mais il est souvent difficile de d\ue9terminer le volume net.Peer reviewed: NoNRC publication: Ye
