Architecture/Engineering/Construction Industry UpdateASTM C90-11b - Hollow Loadbearing Concrete Masonry UnitsIn late 2011 ASTM C90, the material specification for hollow loadbearing CMU, was modified to permit the cross-webs of units to be configured in different ways to meet specific project needs and performance require-ments. As this allowance works its way into local construction, here is a short review of how this new flexibility on unit configurations can benefit your next s changed ?Under new C90 requirements, web configurations are no longer regulated by their thickness, but rather the cross-sectional area of the web connecting the face shells of a , this new requirement means that for every square foot of unit surface, no less than (4193 mm2) of web must connect the front and back face shells, with no web measuring less than in.
