Estudo do melhoramento do solo de fundação com adição de pó de vidro silicato

Abstract

The soil is one of the main elements of the civil construction, responsible for supporting the loads acting on the structure and dissipating them, being diversified as granulometry, chemical composition, rock of origin and other properties, being able to support or not the structural loads without causing damages to work. It should be emphasized that solutions must be found that cover a low cost, combined with a good efficiency to solve the problem, one of the solutions being the chemical stabilization of the soil, which consists in the addition of a product that improves soil characteristics. Thus, the present work has the objective of evaluating and comparing the soil characteristics by adding silicate glass powder obtained through non-returnable glass bottles, performing the soil characterization, compaction and direct shear tests. result to be compared to soil sample without addition of any stabilizer, and to analyze the possibility of the use in superficial foundations. For the study, proposed the use of a direct shear equipment held in unsaturated soil. The characterization of the materials studied (soil and ground-glass) with the levels of 0 %, 5% and 10% of powdered ground glass in the weight of soil.The addition of glass powder not provided improvements in mechanical characteristics of the ground, however the glass powder can be used as a way of minimizing the generation of waste in nature.
