Adherence of Cement-Sand Mortar in Masonry Stacks with the Addition of Lime or Interior Adhesive, Cajamarca, Peru

Resumen

Masonry is a construction technique most used in buildings, one of the most common failures being the lack of adhesion between its units, so in this research the influence of the addition of lime or gray interior glue on the masonry has been evaluated. mortar adhesion. This investigation aimed to determine how much the addition of these materials influences the property of adhesion between the mortar and the brick, in an economical way with a significant improvement (Integral) in the Cajamarca region or in similar conditions. For this, adhesion tests were carried out on the mortar with a 1:4 proportion of cement and sand, with the addition of different proportions (1/8, 1/4, 1/2, 3/4) of lime or interior glue, performing 4 batteries of three units for each experiment, with a total of 90 batteries. The results indicated that the two additions provided more adhesion in all samples with respect to the standard sample, with the 3/4 lime sample being the one that improved by more than 90.68% with respect to the standard sample and with respect to the glue the maximum improvement was with the 1/8 sample of interior glue with 45.57%. These findings suggested that the addition of lime or interior glue can be an effective strategy to improve the adhesion property in 1:4 semi-industrial masonry mortars, with lime being the most effective addition.
