Influencia del polvo de vidrio reciclado en la succión matricial de una arcilla expansiva y su potencial de expansión

The present research topic focuses on verifying the influence caused by recycled glass dust in different dosages in soil samples extracted from the province of Manabí, canton Rocafuerte, which are characterized by being expansive clays causing structural damage in other civil works caused by the swelling and contraction of the soil due to the increase or loss of moisture in it. There are several ways to stabilize this type of soil, such as using cement and pozzolans that improve the mechanical behavior of the earth. A more economical alternative involves using recyclable materials such as glass powder from recycled bottles. A study based on the ASTM (American Society for Testing and Materials) standards is proposed, where it is proven that adding different dosages of 3, 5 and 7% of glass powder per soil sample causes the improvement of the liquid limits and plasticity index, causing the soil used for the research to improve its characteristics, reducing its plasticity and improving its consistency. The expansion potential is reduced from the high range to the medium coverage with the dosaje of 5% of glass powder; as for the matrix suction potential of the soil, the results vary depending on the gravimetric moisture content of the earth and the percentage of glass dust, causing higher values when the glass dust increases in the soil sample.
