2014 TCA Convention

Controlling Shrinkage and Cracking in Slabs

Kim Basham PhD, PE, FACI


On your last job, did you replace cracked floor panels or repair random cracks at no cost to the owner? If so, you need to attend this session and hear how to troubleshoot and minimize out-of-joint floor cracking.

Learn about the causes out-of-joint floor cracking, concrete shrinkage and restraints, aggregate gradation, tensile shrinkage stresses versus tensile capacity of the concrete, reinforcement, jointing and importance of sawcut timing. Also, hear about various options to control floor cracking and some of the concerns associated with these options.







About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
