Abstract |
As time passes, bridge structures require extension work on bridge in use from various effects such as social economical, or traffic environment change. When the concrete is poured at the connection of extension work initial curing concrete is influenced by vibration of vehicles that are passing through the old bridge superstructure. Concrete at early curing stage in construction site should be properly protected, enough to have established sufficient integrity to withstand outside vibration, impact etc. Currently there is no standard specification or regulation in our country. In this paper, experimental variables were divided by vibration velocity and time of loading, and concrete compressive strength and bond strength were measured.
