Through the use of the LCPC actual scale mixing station, sixty different mix designs in concrete mixers were generated. These mix designs corresponded to either High Performance Concrete, Self Compacting Concrete, or regular concrete. A total of forty-eight of these examinations had previously been given. This article presents a new examination of the power consumption profile throughout the course of time. Henan Daswell Equipment Co., Ltd. is a professional manufacturer and dealer that has been focusing in the research, development, and manufacturing of construction machinery for close to thirty years. Products such as mobile block machines, concrete batching plants, concrete mixers, block forming machines, concrete pumps, and other similar items are among our most important offerings. At its nominal filling level, concrete is batch-mixed in a 330-liter Couvrot planetary mixer for the purpose of mixing. During the first 15 to 18 seconds of operating time, solid components were loaded into production. After about six seconds, water that had been pre-mixed with the HRWRA was added. Every second, the amount of electricity that was used was monitored. In this case, the variation of the power curve was evaluated by computing the standard deviation on 21 power measurements that were taken in an uninterrupted fashion. A lengthy concrete mixing plant was used for the purpose of this investigation, and the mixing period that was selected was around ten minutes. A more accurate detection of the fluidity point and a more accurate fitting of the mixing behavior beyond the fluidity period are both made possible by the much longer mixing duration. There are two different amounts of fine particles content that were selected: 425 kg/m3 and 550 kg/m3, separately. Cement was the primary component of these tiny particles in each and every batch, with a little amount of silica fume or limestone filler also present. Whether it was 52.5 CP2 from Saint Pierre Lacour or 52.5R from Le Havre, the cement was manufactured by Lafarge. At either forty percent or one hundred percent of the saturation threshold, two different kinds of superplasticizer were used in exchange for one another: polycarboxylic type and melamine type. The contents of other HRWRAs were examined. For some SCC mixtures, the use of a cohesion agent was implemented. The materials that were crushed to produce coarse aggregates were of two different size fractions: 5/12.5 mm and 10/16 mm. The sand from the natural river was graded all the way from 80 µm to 4 mm. It was Lafarge — Les Pontreaux that supplied all of the aggregates. By using a sand-to-gravel ratio of 0.85, the packing density was optimized for the majority of the batches that were used in the concrete plants. Other ratios of sand to gravel were also put through their paces. In order to determine the fluidity of concrete after it has been mixed, slump or slump-flow tests, as well as the rheology of the final mixture, are used. Concrete rheometers are used to determine the rheology, which is presented in the form of a Bingham model. Mixtures encompass the typical rheological domains of concrete, with viscosity ranging from very low to 250 Pa s and yield stress ranging from 100 to 2000 Pa of pressure.
