Estabilización volumétrica de arcillas expansivas utilizando materiales habituales y modernos para el sector de Puerto Seco en la ciudad de Loja

Abstract

Abstract: The present study consists of obtaining a sample from the Puerto Seco sector due to the fact that it has permanent deformations and this behavior is an indicator that the soil is prone to behave like an expansive clay when in contact with water and with characterization tests. of the soil it was determined that it has a medium plasticity (23%), low resistance index (2%), a high expansiveness index (5.10%) and finally contains 20% of the montmorillonitemineral; parameters that show that this type of soil behaves like a clay with medium to high expansiveness and to counteract this expansiveness, three stabilizing agents, cement, lime and bagasse ash were implemented, which by adding 3 and 5% of the chemical modifier, results were obtained with respect to the mixture properties, showing that incorporating 5% of lime into the soil provides a satisfactory volumetric stabilization since its values comply with local specifications. On the other hand, cement and bagasse ash with 5% is not enough to comply with the parameters established in Ecuadorian regulations.
