EXPERIMENTAL DETAILS OF PAVER BLOCKS FOR LOW VOLUME TRAFFIC WITH QUARRY FINES

Solid unreinforced pre-cast cement concrete paver blocks is a versatile, aesthetically attractive, functional, cost effective and requires little or no maintenance if correctly manufactured and laid. Paver blocks can be used for different traffic categories i.e. Non-traffic, Light-traffic, Medium-traffic, Heavy-traffic and Very heavy traffic. Concrete block paving is versatile, aesthetically attractive, functional, and cost effective and requires little or no maintenance if correctly manufactured and laid. Most concrete block paving constructed in South Africa has performed satisfactorily but there are two main areas of concern: occasional failure due to excessive surface wear, and variability in the strength of blocks. Paving block is a very common and popular method of hard landscaping that is suitable for various applications including: driveways, paths, patios, public utility areas, garage, forecourts and roads etc. IS 15658 : 2006 says that paver blocks can used in Low Volume Traffic Roads when it is casted by M 35 grade of concrete and 60 mm thick. In this project 60 mm thick and paver blocks of M 35 concrete grade is casted. quarry fines which is waste product of stone industry and generated as a waste during the process of cutting and crushing of stones are going to use as fine aggregate Fine aggregate is going to replace by quarry dust (which is retained on 4.75 mm IS sieve) upto 100% at an interval of 10% and test like compressive strength along with flexural strength is performed on paver blocks. Workability of the concrete is also checked.
