Investigating the Effects of Mixing Time and Mixing Speed ...

Sep 03, 2020  The mixing process performs a critical role in the concrete microstructure, which defines the final product’s quality. Optimizing mixing time and mixing speed during the mixing process can reduce the unit price and energy consumption without impacting product quality. Furthermore, the energy consumption to manufacture self-consolidating concretes (SCC) is more than that of conventional ...

May 25, 2020  A method is proposed in this paper to estimate the workability of self-compacting concrete (SCC) in different mixing conditions with different mixers and mixing volumes by recording the mixing process based on deep learning (DL). The SCC mixing videos were transformed into a series of image sequences to fit the DL model to predict the SF and VF values of SCC, with four groups in total

Estimating the workability of self-compacting concrete (SCC) is very important both in laboratories and on construction site. A method using visual information during the mixing process was proposed in this paper to estimate the workability of SCC. First, fourteen specimens of concrete were produced by a single-shaft mixer. A digital camera was used to record all the mixing processes.

Abstract: The topic of the work is to understand the interaction of an ultrasonic wave in concrete or in granular materials. This wave's propagation is currently used to analyse qualitatively and quantitatively the evolution of concrete. Many analyses or processing are tested to measure the influence of the microstructure evolution on the wave velocity or attenuation.

Feb 07, 2017  Artificial cooling of concrete by embedded pipe was first tested on the Owyhee Arch Dam Project in the United States. 1 In 1931, the United States Bureau of Reclamation conducted a field experiment of pipe cooling in the Owyhee Arch Dam. This experiment adopted river water for cooling and verified that pipe cooling can effectively control the inner–outer temperature difference of concrete.
