Traditionally, crack control in concrete masonry has relied on specifying concrete masonry units with a low moisture content, using horizontal reinforcement, and using control joints to accommodate movement. Prior to the 2000 edition of ASTM C90 (ref. 8), low moisture content was specified by requiring a … See more Cracking resulting from shrinkage can occur in concrete masonry walls because of drying shrinkage, temperature fluctuations, and carbonation. These cracks occur when … See more Various building materials may react differently to changes in temperature, moisture, or structural loading. Any time materials with different properties are combined in a wall … See more All wall systems are subject to potential cracking from externally applied design loads due to wind, soil pressure or seismic forces. Cracking due to these sources is controlled by applying appropriate structural design … See more As walls and beams deflect under structural loads, cracking may occur. Additionally, deflection of supporting members can induce cracks in masonry elements. To reduce the potential for cracking, the … See more Webpending on reinforcement needs, such as for crack control or structural strength. Never position a single reinforcement layer below mid-depth. Steel in two direc-tions with the bars or wires in contact with one another is considered “one lay-e r.” For most slabs on grade, position the reinforcement at one-third the depth from the top surface.
