PROPERTIES OF CONCRETE WITH RED MUD AS PARTIAL REPLACEMENT OF CEMENT WITH HYDRATED LIME AND SUPERPLASTICIZER
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
In this research an attempt has been made to produce different grades of concrete using huge industrial waste such as red mud as a partial replacement of cement with the hydrated lime. This project presents the results of investigation on production of concrete members using a combination of materials which predominantly includes red mud and lime. The present study is mainly focused on the compressive strength, split tensile strength, flexural strength and durability properties of concrete, which are the important parameters to be studied in concrete production of different proportion of raw materials for different grades of concrete. However, when used in combination with 30% red mud, cement and 5% lime the composites shows significant compressive strength of 27.3N/mm2 and 50.05 N/mm2 for M20 and M40 grade of concrete. Tensile strength of 2.60 N/mm2, 4.98 N/mm2 for M20 and M40 grade of concrete. Selected combinations of mixes were later used to produce beam of size 500 x 100 x 100mm. These beams are tested for flexural strength of results 2.4 N/mm2 and 3.29 N/mm2 for M20 and M40 grade of concrete. From this study it is revealed that 30% replacement of red mud along with 5% hydrated lime is found to be optimum.
