Characterisation and effects of the Effective Micro-organics (EM) and Industrial Waste (IW) materials as a partial mixture in concrete

Abstract

Researchers keep renewing and updating the concrete technology from day to day. There are a lot of added materials in concrete mixture. The main objective in this study is to investigate the admixture or filler that are economical, environment-friendly, sustainable, and easily obtained. This research focused on two type of material which is locally produced that is material based on Effective Microorganisms (EM) and Industrial Waste (IW) which are used as a partially in concrete mixture. The scope of study only focused on laboratory work to obtain the results. The result indicated in that the application of 10%, 20% and 30% of EM in concrete mixture, can be applied in concrete technology and improve the concrete properties while the application of IW in this study indicated the reduction in concrete properties as the content of IW increased and showed that it cannot replace the conventional material in concrete mixture as filler. This study recommend to extend the research especially concrete containing IW that heated in high degree of temperature (above 500 oC) because this study indicated it was improved the concrete properties on 500 oC. The outcome of the study has developed of new technology in achieving sustainability for affordable concrete structure.
