The rise in demand for traditional building products and the desire for economic development in the construction industry have driven designers and planners to look for 'alternative materials' that can be used in construction. The usage of chemical waste materials and crop by-products is positive for this reason. The chemical, metal, polymer wastes and agricultural products such as Fly Ash, metal slag, plastics, and Rice Husk Ash may be used instead of cement due to their pozzolanic nature, which otherwise involves a wide area of land for disposal. Besides that, this paper will discuss the results of previous researches on various types of wastes that have been used as the partial replacement to cement in concrete and their physical properties have been studied as well as the physical properties of these hardened concrete such as strength and workability. In fact, using available resources is important to minimize pollution to the environment since these industrial waste materials are expensive to be disposed of and has negative impact to the society and the environment as well. Hence, this research paper will propose a high-strength concrete mix design among the reviewed wastes as a replacement for cement with a variety of ratios, as well as the methodology and the techniques to be followed to produce the desired concrete. In conclusion, the main scope of this research paper was targeted which is to review and to observe the effects of using various wastes as partial cement replacement on concrete properties. From the conducted comparison of various wastes, it can be concluded that the main objectives were accomplished. [ABSTRACT FROM AUTHOR] |
