- Abstract
This work aimed to analyze the physical and mechanical properties of mortar with the addition of fly ash and rubber concentrations used on building walls. The mortars had 5 and 10% of fine aggregate mass replaced by rubber and added fly ash in proportions of 10 and 20% according to the volume of cement. Ground fly ash addition in the mortar, in turn, increased the compressive strength by 18% at 28 days compared to the reference mortar, assuring a greater durability against sulfate attacks and presenting lower mass loss during exposure to sodium sulfate. The mortar containing 20% of ground fly ash and 5% of rubber presented tensile adhesion strength of 0.33 MPa at 65 days. A numerical simulation of the mortar microstructure was carried out using the finite element method to study its thermomechanical behavior. Stress distribution and cracking field of the model were also obtained.
