![]() The mixing procedure includes the type of mixer, the order of introduction of the materials into the mixer, and the energy of mixing (duration and power). Its microstructure is determined by its composition, its curing conditions, and also by the mixing method and mixer conditions used to process the concrete. Some procedures used to determine the effectiveness of the mixing will be examined.Īs for all materials, the performance of concrete is determined by its microstructure. This paper will review mixing methods in regards to the quality of the concrete produced. An important measure of the quality is the homogeneity of the material after mixing. Ultimately, the quality of the concrete produced determines its performance after placement. To determine the mixing method best suited for a specific application, factors to be considered include: location of the construction site (distance from the batching plant), the amount of concrete needed, the construction schedule (volume of concrete needed per hour), and the cost. There are two main types of mixers used: batch mixers and continuous mixers. This paper gives an overview of the various types of mixing methods and concrete mixers commercially available used by the concrete industry. ![]() ![]() As for all materials, the performance of concrete is determined by its microstructure. ![]()
