Enhancing the durability, usability, and effectiveness of structures is crucial in modern civil engineering. The aim of the study is to investigate how the properties of cement are altered by the addition of glass fibre (monofilament). In the study, the effectiveness of mortars with different amounts of glass fibre added (at concentrations of 1%, 2%, 3%, 4%, and 5% by weight of cement) is compared. Based on the results of the compressive strength tests, it can be shown that adding glass fibre to mortar mixtures typically increased their compressive strength at various ages for all mix proportions (1:3, 1:4, and 1:5). Glass fibre enhanced the compressive strength for the 1:3 mix percentage, with the 4 percent GF mix displaying the greatest strength values throughout all test time periods. The data for mortar mixtures of 1:3, 1:4, and 1:5 with varied amounts of glass fibre demonstrate that the inclusion of glass fibre often causes an increase in the rate of strength gain. The ideal glass fibre content, however, may change according to the particular curing time and application needs. The inclusion of glass fibre, particularly at proportions of 2 and 3 percent GF for 1:3 and 1:4 blends reduced drying shrinkage in mortar mixes. The findings show that the addition of fibres significantly changes a mixture's mechanical properties, whereas the effect is less pronounced when fibres
are added to a less dense mixture. Overall, the results point to glass fibre-reinforced mortar as a potentially useful material for use in civil engineering applications because of its capacity to boost the durability and effectiveness of modern construction projects.
