INTERPRETATION OF HIGH STRENGTH MASONRY CEMENT EMBODYING INDUSTRIAL WASTES AND POZZOLANIC MATERIAL

ABSTRACT The main prospect of this research is to consume the peculiar industrial wastes (fly ash and phosphogypsum) and pozzolanic materials (hydrated lime and calcined clay) for better solution to tackle the waste generated and the growing need of cement and establish them as cementitious materials for partial replacement of cement. Chemical as well as physical properties of the cementitious materials were carried out to check the compatibility of materials with cement.All the four materials stated above are combined together in different proportions and used as partial replacement of cement in different mix batches. Total 7 batches of mix proportion involving M0 with 0% of cement replacement whereas M1, M2, M3, M4, M5 and M6 representing 60%, 50%, 40%, 30%, 20% and 10% addition of cement replacement respectively. Through critical study of the test results it was found that 10% replacement of cementitious material in OPC 43 gives effective results of compressive strength test and tensile strength test.
