Paver block construction in roads is versatile, attractive and aesthetical, cost effect and requires lesser maintenance cost. The main objective of this present work is to replace the natural river sand with manufactured sand with an incremental increase of 10% and to find out the optimum replacement level in respect of strength and durability properties of paver blocks for M30, M40 and M50 Grades of concrete. The availability of natural sand is depleting due to increase in developmental activities across the world particularly in India. In the current work manufactured sand is used as an alternative sand material in place of natural river sand and accordingly paver blocks were prepared with M-sand with an incremental increase of 10% to 100% replacement. The paver blocks so prepared was tested for its strength and durability property and discussed in detailed and reported. The use of Msand in concrete paver blocks reduces the environmental degradation such as depletion of water table. Hence in this research work an attempt was made to put forward an idea of using the M-sand in commercial products like paver blocks. This will be beneficial to ecological and environmental for sustainable developments towards greener world. © 2020 Alpha Publishers. All rights reserved.
