Abstract

Mortars have many uses in construction: to lighten, sonic and thermal insulation, aesthetic purposes, to protect against environmental attack, repair, conservation, union masonry, etc. Mortar matrices may be Portland cement, lime, gypsum, clay and soil, asphalt or polymers. This work shows the result of the addition of areas of expanded polystyrene spheres (EPS) in three different percentages to the aggregate of a mixture of mortar. Physical and mechanical behaviour is evaluated to assess their behaviour under accelerated attack. The stone aggregate in the mortar was river sand; the cement used was ASTM C150 Type IV; the initial water-cement ratio by weight was 1.01 for each share; all blends met 105 ± 5% flow. The addition of expanded polystyrene spheres (EPS) replaced fine aggregate by 10%, 20% and 30% in each mixture. It was necessary to add a fluidizing agent in cases of adding expanded polystyrene spheres since the fluidity of the mortar decreased. Destructive testing such as simple compression and the accelerated attack took place; non-destructive testing included physical absorption as a percentage and specific gravity were also performed. It is concluded that the addition of expanded polystyrene improved resistance to chemical attack accelerated mortars and reduced the volume and weight, without detriment to the resistance.
