Influence of Cycle Time on the Productivity of Transit Mixers

Abstract

Ready mix concrete is an advancement over the old site mix concrete and is preferred due to its flexibility, time, quality, cost effectiveness etc. Ready mix concrete is transported from plant to site using transit mixers and volumetric mixers. Among which transit mixers are widely used now-a-days. Productivity of mixers therefore contributes towards the success of ready-mix concrete plant and construction site. Productivity of transit mixers depends on the cycle time involved during the process of concrete delivery. So it is necessary to identify and quantify those factors to minimize the cycle time and to increase productivity. This paper deals with the identification of factors affecting cycle time of transit mixers and analyzing the impact of these factors on productivity. Hauling time and time for transit mixer weighment were found to be the major factors that affect the productivity.
