要旨 |
A trial was carried out to prove the validity of applicability of DEM to simulating the mechanical behavior of fresh concrete in sphere dragging viscometer.Given special cares to the devices and data handling,experiments covered the fresh concrete,screened mortar and aggregate to acquire viscosity and yield value.It was found that even for high fluidity concrete such interaction as collusion,friction etc.between sphere and aggregate was obviously observed,which to some extent proved the applicability of DEM.Although DEM can precisely simulate the behavior of aggregate,it needs further modification to more precisely simulate the behavior of fresh concrete. |
