Carbonation of Concrete Carbonation Test of Concrete: Carbonation of concrete occurs when carbon dioxide in the air reacts with calcium hydroxide and hydrated calcium silicate in the concrete, resulting in the formation of mostly carbonates (CaCO3). Carbonates are formed during these chemical reactions, resulting in the permanent retention of this CO2. Carbonation happens when CO2 …
Segregation of Concrete Segregation of concrete is defined as the process of separating the ingredients of a heterogeneous mixture so that their distribution becomes irregular. Additionally, segregation refers to the separation of new concrete components, resulting in a non-uniform mix. This is a separation of coarse aggregate from the mortar that occurs as a result …
Prevent Concrete Curling: Curling of concrete is a flaw that occurs in concrete slab elements. Curling refers to upward or downward bending of the edges of a slab. Curling of concrete slabs is primarily caused by temperature differences between the slab’s upper and bottom surfaces or by variations in the slab’s moisture content. This post …
Understanding the Fire Resistance of Concrete: The capacity of concrete to resist fire or to provide protection against fire is referred to as its fire resistance. This refers to a concrete structural element’s ability to continue performing the required structural function or to contain fire, or to do both. The time period during which the …
Defects in Concrete Structures: Cracking, crazing, blistering, delamination, dusting, curling, efflorescence, scaling, and spalling are all examples of defects in concrete structures. These defects may be caused by a variety of different factors or causes. This article discusses 8 Common Defects in Concrete Structures & How to Prevent Them.
