A Comparative Study on Using Laterite and Sandstone Aggregates on Mechanical Properties of Concreteoducts. Mining industry is one such major source of waste materials. Sandstone, which is overlying coal seams, is the largest quantity of waste rock being produced by coal mining industry. Laterite is another waste comes from small scale quarries. An attempt is made to assess the use of laterite-GGB

Removal of Methylene Blue from Aqueous Solution: An Approach of Environmental Friendly Activated Caamount, initial dye concentration and contact time. Studies showed that as the contact time increases relatively there will be an increase in the removal of methylene blue from the aqueous solution. There was also a comparative increase in the removal of dye with the increase in dosage of adsorbent.

Investigation of Dredged Sediments Reuse as Building Materials,ments are annually dredged in the ports over the world. In Le Havre harbor the annual dredged volume of sediments is close to 1.5 Mm., which are mainly dumped at sea. Because of its perpetual availability and mineralogical characteristics, the sediment is regarded as a suitable raw material for terr
