| description | Plaster is a very useful material in construction, but it is responsible for producing waste in the
manufacturing process and also the demolition works. This work seeks alternatives that reduce the
production of waste in the manufacturing process using plaster additives in their composition and also
to assess the damage caused by improper disposal of waste produced in buildings demolition, due to
its possible use in fish farms. Different modified plasters were evaluated on various parameters such as
cure time, appearance, resistance and morphological changes. The modified plasters with diatomaceous
earth show good results. Waste of plaster and pure plaster were submitted to leaching tests at different
pH values to evaluate its behavior in two different periods of time. It was analyzed parameters such as
conductivity, turbidity and calcium contents in the leached samples, checking that the plaster and your
residue influence the aquatic environment. It was found that pH, conductivity and turbidity are altered
when subjected to gypsum concentrations. |
