Abstract:

Advancements in technology enhance not only human comforts but also damage the environment. Production of Portland cement is responsible for the evolution of high amount of CO2. Nowadays the use of concrete paving blocks has been increased rapidly. In recent years, almost every mineral producing country is facing the problem of better utilization of mine waste because of its accumulation and lack of suitable storage space. In order to reduce the use of Portland cement, iron oxide powder a mine waste is used as a partial replacement to cement in the production of concrete paving blocks. Fibres used in concrete arrests cracks, increases resistance to impact/abrasion and greatly improves quality of construction. The present study aims to determine the optimum amount of cement replacement required to achieve a desired compressive strength of 40MPa for the concrete paving blocks with polypropylene fibre. The replacement level of iron oxide powder with cement is from 5% to 25%. The variation of polypropylene fibre is from 0.1% to 0.4%. The work also includes the evaluation of various properties like compressive strength, flexural strength and abrasion resistance of the concrete paving blocks.
