An increasing interest has emerged in correlating the output of the concrete mixing truck to values obtained by rotational rheometers. The output of the former has usually been the hydraulic pressure needed to turn the drum. In such research, experimental errors can be higher than usual, which ...

Measurement of workability of fresh concrete using a mixing truck of these experiments are discussed and compared with data provided by the ICAR rheometer, a portable rheometer designed for measuring concrete rheology. The... S Amziane,Ferraris, C.F.,Koehler, E.P. - 《Journal of Research of ...
Thus, an objective of the present invention is to monitor and to control the rheology of the concrete mix during transit from the ready-mix plant (or dispatch center) to the site of placement (or pouring), using the truck's mixing drum as a rheometer and monitoring equipment that is prese...
(a) Mixing unit in the RMC plant. (b) Discharge of concrete from the mixer to the truck. 1.2. Energy Consumption during the Mixing of Concrete in This Project The concrete is manufactured in the RMC plant in many ways, such as thoroughly mixed state and partially mixed concrete, that is...
brittle, then microcracks develop in it and cracking of the interface between aggregates and binder occurs[1]. It is prone to go fragile and stiff due to exposing to heat, oxygen, andultraviolet lightduring storage, mixing, transport, and laying down, as well as during service life[2–4]...
