Abstract

Glass fibre-reinforced mortar is a new construction material with characteristics that differ from conventional mortar. Glass-fibre reinforced mortar is commonly used for one or more of the mentioned reasons. Fire loading and earthquakes are examples of structural problems while handling hazards including transit, stand stocking, and erection stress (to withstand differential stresses). Glass fibres were discovered to vastly enhance flexural and tensile strength. In this investigation, three glass-reinforced mortar mixes with a glass fibre content of (0,0.25, 0.5, and 0.75% by volume fraction) were chosen. To investigate the influence of glass fibres, two hardened experiments were performed: the first was a bulk dry density test, and the second was an ultrasonic pulse velocity test. Data were created to investigate the influence of fibreglass on mortar using bulk dry density and ultrasonic pulse velocity measurements. The outcomes showed that the presence of short and randomly distributed glass fibres has a positive influence on ultrasonic pulse velocity measurement and that further addition of glass fibre (0.25% to 0.75%) improved mortar by lowering ultrasonic pulse velocity values and giving lower density than control samples.
