or common wall rather than being curtailed on each side of the wall.

Construction material subjected to repetitive or cyclic loading have to be qualified for their fatigue behaviour. Generally their behaviour is considered satisfactory if they withstand two million cycle of repetitive loading without distress or failure at that required mean stress level and range stress.
The recent research in reinforcing Portland cement based material with randomly distributed fibres was spurred by pioneering research or fibre reinforced concrete (FRC) conducted in the United state in the 1960s.The addition of fibre in the co ....etc
