Abstract
In constructing slender structural elements with limited formwork space, where reinforcement density and the presence of other elements are high, using mortar with both high strength and excellent flowability is essential. This study evaluates the effect of mixture composition on the strength and workability of high-strength polypropylene (PP) fiber-reinforced mortar, aiming to provide a dataset for developing high-strength mortars suitable for practical applications. Mortar mixtures were prepared using white Portland cement, ground granulated blast furnace slag (GGBS), silica fume (SF), and varying PP fiber contents (0.1%–0.4% by volume). Investigated properties include flowability, compressive strength, flexural strength, and abrasion resistance. Results showed that mixtures with binder content ranging from 740 to 820 kg/m³ achieved compressive strength over 70 MPa with good abrasion resistance. Chemical admixtures below 1% significantly enhanced workability without reducing mechanical performance. Among all dosages, 0.2% PP fiber content was optimal, yielding balanced improvements in strength and workability.
