The Contractor should establish a system for regular sampling and testing of concrete to the approval of the Employers Representative. TMT bars have high fatigue resistance to dynamic / seismic loads due to its higher ductility. But Maximum size of aggregate generally on site used are 4 0 mm. This formulation works very well since concrete is very compressive; simple to manufacture on-site, steel is very tension-intensive and inexpensive. In general, the minimum time betweenplacingof the concrete and the removal of forms is two days for unloaded walls and other side forms, seven days for supporting walls and conduits, and 14 days for bridge decks.
