Types of Chemical Attacks on Concrete Structures

When a concrete structure is prone to chemical actions its durability gets affected. The chemicals may cause cracking of concrete, volume change and deterioration of structure. The life of structure reduces and it can lead to failure of structures. Different types of chemical attacks and their effects on concrete structures are explained below.REINFORCED CONCRETEReinforced concrete (RC) is a structural composite made of plain concrete and reinforcing steel. cameroon reinforced concrete tank chemical volume Heat of Hydration: The chemical process during setting and hardening of concrete that result in the generation of heat cameroon reinforced concrete tank chemical volume Occupy 70 80% of the volume of concrete and, therefore, plays an important role in defining the properties of concrete.CRACK CONTROL IN CONCRETE POTABLE WATER TANKSConcrete Water Tanks Section 5.12, The net liquid loss for a period of 24 hours shall not exceed 0.05% of the tank capacity AWWA D115 Tendon Prestressed Concrete Water Tanks Section 6.1.4 Crack Control in Concrete Tanks
