WebSep 1, 2012 · In the 1999 edition, ACI decided to greatly simplify crack control requirements due to increased evidence suggesting a reduced correlation between crack width and reinforcement corrosion. Beeby [19] and [20] showed that corrosion does not correlate with surface crack widths in the range normally found with reinforcement … Webreinforcement. Based on the results of the project, the research team makes the following recommendations: • Textured-epoxy and hot-dipped galvanized bars provided superior crack control performance in laboratory tests relative to the smooth epoxy bars.

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.
