WEATHERING OF HARDENED CONCRETE

Cement concrete behaves like an artificial calcareous rock and is vulnerable to weathering, resulting in a shortened life span of the structure. Damage to concrete due to weathering has been studied in simulated laboratory conditions on over 540 concrete specimens. The experimental results confirmed that the concrete suffers damage and consequently loses its compressive strength to the extent of 30-40%. A richer concrete with lower water-cement ratio and replacement of 20% cement, by weight with flyash is shown to enhance the resistance to weathering. Based on the data obtained, it is recommended that flyash be added to concrete hydraulic structures like canal linings, spillways and dams. (TRRL)
