Paper Details

Concrete paving blocks have been widely used in various countries to a certain extent of time as a standardpractice for providing pavements. It is used because of its firmness in regions such as walkways, parking lots and parkswhere normal type pavements are not suitable or less resilient due to many operative and environmental restraints. TheMarble industry is dumping the marble powder in their surroundings directly impacting the environment in differentforms. In dry form, its particles moving with blowing air create dust pollution. On other hand, this powder flows withrun-offs and ultimately affect aquatic life. Moreover, the demand for cement is quite high in developing countries due torapid infrastructural growth which results in supply paucity and increase in cost of material. Experimental study wascarried out to conclude various mechanical properties of concrete paving blocks having compressive strength more than7200 psi in comparison using marble powder from three distinct sources as cement replacement. Concrete paver sampleswith varying proportions 0%, 10%, 15%, 20%, 25% and 30% of marble powder from different sources were casted andtested to find the properties like compressive strength with respect to 7 days & 28 days, flexural strength and waterabsorption with respect to 28 days. From the results it was concluded to replace the marble powder up to 20% byMohmand source, 15% by Buner and 10% by Ziarat with cement to achieve improved properties. The usage of cement incivil works is increasing day by day and its demand is quite high in developing countries thus leading to environmentalpollution due to emission of CO2 during production process. Replacing cement with marble powder up to certain limitwill not only reduce the CO2 emissions and manufacturing cost of pavers but will solve the disposal problem of marblewaste in effective way.
