Feasibility of Using a Concrete Mixing Truck as a

The mission of this study was to evaluate the feasibility of using a concrete truck mixer as a rotational rheometer. To succeed, it is necessary that the methodology measure fundamental rheological parameters (plastic viscosity and yield stress) during the mixing process.

Feasibility on Using a Concrete Mixing Truck as a Rheometer

2006-6-14  The most fundamental are the tests based on rheology, such as the rotational rheometers . Therefore, there is a need for a relatively simple test that could be used in the field to fully characterize fresh concrete flow properties.The main scope of this study was to evaluate the feasibility of using a concrete truck mixer as a rotational rheometer.

concrete mixing truck in transit to a jobsite [4,12]. Both studies were based on a very limited number of concrete measurements. The present study includes 21 concrete mixtures made using one concrete mixing truck. The range of plastic viscosity and yield stress was varied by incremental addition of either water or chemical admixtures.

Concrete mixing truck as a rheometer - ScienceDirect

2020-1-1  Relative to the SRF (see Section 3.1), the concrete sample is stationary at time t = 0 s. As a consequence, the rate of work components W ̇ K E (t) and W ̇ η (t) begins at zero as shown in Fig. 2.With the start of rotation, some wave generation occurs due to the fact that the concrete sample is interacting with the helically shaped geometry of the mixing blades inside the drum.

110 Measurement of Workability of Fresh Concrete

2005-3-4  2.3.1 Using the Mixing Truck as a Rheometer To transform a truck mixer into a rheometer requires that at least two entities be measured: the rotational speed of the drum and the power consumption or torque used by the mixer motor during rotation. To obtain both the yield stress and the viscosity it is necessary to obtain data at several speeds.

2005-1-1  In summary, this preliminary study showed the feasibility of measuring the slope and intercept of the torque vs. speed plot from a mixing truck drum as a means of determining concrete workability. The yield stress measured with this method correlated well with the results of the slump test and the ICAR rheometer.
