This investigation reports the influence of industrial waste material namely slag on the performance on cement composites. Recall that slag is a landfill material resulting from the extraction process of steel making. The scrap material was physically treated by crushing followed by ball milling and screening. The slag was mixed with the Portland cement and compared with traditionally Portland cement composite. The mix was casted into the desired moulds and allowed to cure at room temperature for 48h followed by o...

Energy needs are increasingly growing due to the mechanization of industry by the industrial revolution, increased production in line with increased population, higher prosperity levels, and abundance of electrical tools. Mineral oil get polluted chemically and physically and become unusable after a certain amount of usage. As natural resources are limited, mineral waste oil need to be recycled in order to reduce production costs and achieve sustainable energy acquisition. Cement factories are energy-intensive bus...

Metakaoline is a relatively new pozzolanic additive, obtained by calcination of kaolin clay at relatively low temperatures. Themselves pozzolanic additives are known for a very long time. Currently, there is interest to pozzolanic materials again, because their usage allows reducing the total environmental impact and cost of cement. The influence of metakaoline on hydration and hardening of cement was studied. The usage of metakaoline as the additive to cement composition increases the strength of cement stone. Be...
