The final report of a study to determine nature and extent of volume change in concrete masonry walls as affected by moisture content of the units at the time they are lard and also to determine the effect of wetting the wall subsequent to drying. Purpose of the study was to find a way to reduce or eliminate volume change and shrinkage. Measurements were taken on 38 panels of concrete masonry built with block of different ages (sand and gravel, Haydite, cinders granulated slag, and crushed limestone aggregates). the volume change was greatly reduced by using air-dry pressure steam curing also minimized s h units. High-rinkage.
