Desarrollo de un mortero de cal y aceites como impermeabilizante para estructuras de concreto

Abstract

Abstract: The use of oils to improve the physical and mechanical capabilities of lime mortar, were constructively ecological applications, generated research interest due to their hydrophobic capabilities. The research approach was directed mainly to: LO (linseed oil), NCO (unused cooking oil), RCO (residual cooking oil), BO (used vehicle oil), RCO and BO being the most common residual oils. of cities and used to produce hydrophobic lime mortars, used as waterproofing for cracked concrete structures. The physical and mechanical capacities, compressive strength and the decrease in water absorption were investigated. A decrease in water absorption was obtained in the lime mortars with oil of: 41, 451% RCO; 24, 679% LO; 23, 981% NCO; and 14, 231% BO; the lowest results of water absorption decrease are from BO as it has no influence on the lime mortar matrix and the highest value was obtained by the RCO mortar which had an influence on the lime mortar matrix.
