Experimental Approach to Study Performance of RMC Plants in Western Maharashtra Case Study

Abstract

Increase in the use of concrete in construction has brought with it a rapid increase in the number of ready mixed concrete plants.In order to ensure that concrete produced is of desired quality, it is necessary that quality control is exercised at all the stages right from receipt of raw material to delivery of concrete at site. Thus, while planning to use Ready Mixed Concrete (RMC), it should be ensured that producer of RMC has adopted quality assurance programme. This paper is an attempt to study the effect of proposed schematic RMC process chart and type of fly ash on performance of RMC plants in western Maharashtra. This paper presents the results of an experimental study carried out to determine the concrete compressive strength at different RMC plants using fly ash. The various control charts are drawn to know the corrective measers to be takenduRMC production. The used fly ash may be classified or unclassified. The tests are carried out in accordance with IS standards. In this study, standard deviation of RMC plants with classified fly ash & unclassified ash was also investigated. From the results, it can be concluded that, performance of RMC plant is significantly affected by schematic RMC process chart and type of fly ash.
