What Is Expansion Control Joint at Paul Bennette blog

What Is Expansion Control Joint. Contrary to expansion joints, control joints are not intended to handle significant movement caused by expansion or contraction. An expansion joint in a concrete structure is a separation provided between adjacent sections to allow movement due to dimensional increases. Instead, they are strategically placed to control and minimize the occurrence of cracks due to shrinkage or drying of concrete. Expansion joints permits thermal contraction and expansion without inducing stresses into the elements. Control joints are used to prevent cracking. Control joints protect concrete surfaces from shrinkage cracks due to concrete drying. Basically, control joint is the action of making a saw cut groove and weaken the slab where we think the crack may occur due to shrinkage (mostly at the middle of the slab). Control joints help control cracking due to shrinkage, while expansion joints accommodate the movement of concrete. Expansion joints, or isolation joints, are used between two different concrete pours, or where concrete meets with another material or even a structure. Control joint vs expansion joint: This way the cracks developed under the slab find its way at the weak point (the point we have grooved) and avoid spreading all over the slab. The main difference between control joints and expansion joints in concrete is their purpose. An expansion joint is designed to absorb safely the expansion and contraction of several construction materials, absorb vibrations, and permit soil movements due to earthquakes or ground settlement.
