Cracked concrete can lead to safety issues, water leakage, durability problems, shortened service life, poor aesthetics, and costly repairs. Minimizing cracking is a challenge, but fortunately, there are options to minimize and control concrete cracking. Concrete cracks because it fails in tension; and a common cause is shrinkage. This presentation will describe typical influencing factors that lead to concrete shrinkage, plus options and construction practices that can mitigate shrinkage to control cracking. This presentation will provide information that architects, engineers, and specifiers can use to enhance project specifications to help ensure more sustainable, and durable concrete construction.
