Presented By: Er. <> Join TheConstructor to ask questions, answer questions, write articles, and connect with other people. When concreting is done in summer at high temperature, contraction due to drop in temperature in winter is high leading to thermal cracks. Creep occurs more. Foundation Movement and Settlement of Soil. The permeability of cement paste is a function of water-cement ratio given good quality materials, satisfactory proportioning and good construction practice; the permeability of the concrete is a direct function of the porosity and interconnection of pores of the cement paste. Thermal Movement: Thermal movement is one of the most potent causes of cracking and call for serious consideration. Fill in the groove with polymer modified mortar (for wide cracks) or with polymer modified cement grout (for thin cracks). Flooding soaks the walls of a building for a long time.

Leakages should be attended to at the earliest possible before corrosion of steel inside concrete starts and spalling of concrete takes place. When the span of a beam or slab is long and the load at the end is low, deflection causes cracks in the support walls. When two or more residential houses of more than 20 m length are constructed in a row. Reinforcement corrosion will produce iron oxide and hydroxide on steel bar surface, consequently its volume increases. Structural cracks. Beam may be kept 150 wide to give sleek look. The concrete may crack as a result of expansive reactions between aggregate, which contains active silica, and alkaline derived from cement hydration. Moisture Movement: Most building materials have pores in their structure. Non structural cracks do not endanger the safety of building, but they create an impression of faulty work or instability. This can be avoided by stopping the construction of trees that has lateral growing roots nearby. Carbon dioxide penetrates into the concrete through the cracks and speed up carbonation around the cracks, thus shortening the structure usage. Unevenly loaded walls suffer huge variation in stress in different parts which causes cracks in walls.
