| Sumario: | Currently oyster shells "Crassostrea virginica" commercially exploited in Tabasco, represent a pollution problem. Because people after consuming the edible part of the scallop, discarded on the streets or in public places and even in landfills shells, causing bad aspect to the place, poor hygiene and spread of pests. Therefore, through this research it is to provide a solution to this problem of pollution and recycle this waste material for environmental purposes for construction. The shells were collected and selected in different sizes and subjected to coarse grinding treatments with manual fracturing and dry grinding in a ball mill. Subsequently, these oyster shells were heat treated for calcining at 500, 700, 800, 900 and 1000°C. The powders obtained with the two treatments were separated with a vibrating table to perform the sieve analysis. Through analysis by X-ray diffraction (XRD), it was found that the powders are composed of CaO, CaOH and CaCO3. By these results the feasibility of using this waste oyster shells as a material for mortar used in the construction is proposed. |
