Abstract
This study presents the results of a lightweight self-compacting concrete reinforced with sisal fibers. Lightweight aggregates such as expanded clay, pumice, and expanded polystyrene were used as lightweighting materials, replacing up to 30% of the coarse aggregate by volume. Different volumetric fractions and lengths of sisal fibers were added: 0.1%, 0.2%, and 0.3% by volume, and 2.5 cm, 5.0 cm, and 7.5 cm in length. To analyze their influence on workability, the slump test and T500 were used; mechanical behavior was determined through compression and tensile tests at different curing times. The results showed that in the slump test, all mixtures fell within a range of 70 to 80 cm, and the T500 values ranged from 4.3 to 7.2 seconds, including the specimens with sisal fibers. Replacing coarse aggregate with lightweight aggregate and adding sisal fibers negatively affects compressive strength regardless of curing time; however, the presence of the fibers improves tensile strength.
This study was conducted to investigate the effects of fiber reinforcement on the mechanical strength and energy absorption capacity of concrete under varying watert/cement(w/c) ratios and aggregate gradations, using commercially available sikafiber and polimono fibers. Using the Taguchi method, four levels of w/c rati...

Introduction: Self compacting mortar is known as a highly fluid mortar that can flow and fill all spaces under its own weight without vibration or compaction. This experimental work aims to produce a self-compacting mortar (SCM) that can be used to repair damaged structural concrete by replacing a proportion of ordinar...
This study aims to investigate the effects of recycled polyethylene terephthalate (PET) fibers and expanded polystyrene (EPS) beads on the mechanical behavior of self-compacting concrete (SCC) exposed to elevated temperatures up to 600°C.
Five SCC mixtures were prepared: a reference mix, an EPS-modified mix...

Concrete is a commonly used construction material, although it possesses brittle behavior and low tensile resistance. This research evaluates how adding steel fibers and colloidal nano-silica influences the strength characteristics of M30 grade concrete. Concrete specimens were prepared using steel fibers ranging from...

This study investigates the combined effects of metakaolin (MK), crumb rubber (CR), and polypropylene (PP) fibers on the mechanical and durability-related properties of hardened Roller-compacted concrete (RCC). MK was used as a partial cement replacement at levels ranging from 0% to 20% by weight of cement, while PP fi...
