Types and Causes of Concrete Deterioration - Cement

2014-4-14  leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan- sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2). Steel corrodes because it is not a naturally occurring material.

What causes concrete deterioration?

2022-5-1  Concrete deterioration can occur through fouling, disintegration, erosion, reinforcement corrosion, delamination, chipping, alkaline aggregate reactions and concrete cracking. Water is the most common cause of concrete deterioration. Because concrete is porous, water can seep into the concrete and reach the structure below.

Different types of Deterioration in Concrete Structures

2021-1-16  Chemical attack is one of the more common causes of deterioration of concrete in industry today. Animal fats, natural and artificial oils, acids, alkalis, and various industrial salts are all damaging to concrete. Chemical attack occurs due to pollution products and following discharge activity on the insulator surface.

2022-3-25  Concrete deterioration can occur through fouling, disintegration, erosion, reinforcement corrosion, delamination, chipping, alkaline aggregate reactions and concrete cracking. The freeze/thaw cycle also affects the soil. The soil settles differently in the warm months than when it is frozen. This fit can crack and break concrete foundations.

Concrete Deterioration - an overview ScienceDirect Topics

Freeze and thaw cycles are a major cause of concrete deterioration in the continental type of climatic environment, especially when the surface of the material is not protected with a watertight cover. These cycles can result either in surface scaling and spalling, or in material volumic expansion which usually induces a network of cracks.
