Abstract
Flood is considered to be one of the most frequent disasters in the world. It occurs due to rainfall excess which causes huge run-off. During flood streets get filled with water and storm water sewer gets flooded and filled to their maximum capacity. This is due to laying of impervious bed everywhere. No fines concrete pavement had been used in many countries to overcome the problem of excess surface run-off. But the problem with no fines concrete is, it has less strength also it clogs more often. In this paper, a solution is suggested tonegotiate the problem by using perforated concrete as pavement material. This pavement can be made by providing through holes in concrete block with holes of different diameter and cavity percentage. A mix proportion for M40 grade concrete was designed and cubes were tested for 7, 14 and 28days. The compressive strength of perforated blocks was tested. The strength of perforated block was reduces a % cavity increases. However, the strength of block can serve the purpose for footpath, low volume traffic pavement and parking area.The perforated blocks will prove to be better substitute for no-fines concrete giving higher strength and lesser clogging problem than no-finesconcrete.
