Improved brick masonry quality 

Masonry mortar is mixed at the construction site by adding water to fabric made dry mortar. Unlike other mixing processes on site where weight or volume gives the mixing ratio, masonry mortar is mixed to the preferred consistence of the mason. However, variation in the mortar water content has a major impact on the bond between mortar and brick, and thus on the quality of the finished brickwork.

Using wet masonry mortar gives best adhesion to brick and thus best flexural strength, initial shear strength and rain resistance. The variation in mortar water content used at Norwegian construction sites is large and influence the brickwork quality considerably. We recommend a clear indication of the water addition to the fabric made dry mortar to ensure stable and good brick quality.
