“…Recently, as the space of architectural structures are getting longer and larger, expansion joint is increasingly applied to large-scale structures such as shopping malls and logistics centers. Expansion joint is a functional joint that is designed to absorb the deformation of a structure caused by temperature change, drying shrinkage, settlement, vibration, and so on (Klein et al, 2009). However, expansion joint complicates the process and delays the construction period.…”

The current design standards refer to the necessity for expansion joint, there are no clear limitations as to the location and spacing of expansion joint. To find the effect of the rebar ratio, structural tests were performed on Samples with adjustments of the rebar ratio. As the rebar ratio increases, the average crack width decreas-es. The number of crack increase but the concrete crack width decrease. Also, comparing results of experiment with those of analysis, it is necessary to apply the concrete tensile strength, which reflects the contribution of the reinforcement ratio.

Palm oil empty fruit bunch (OEB) is the largest source of waste in the production of crude palm oil. Utilizing this waste in various applications can help reduce its volume and mitigate adverse environmental effects. In this study, fibers from OEB without any chemical treatment are introduced into Ordinary Portland Cement (OPC)-based mortar to partially replace fine aggregates, aiming to reduce the mortar’s density. The goal of this experimental study is to observe the mechanical and physical performance of the samples according to the effect of the addition of OEB. The composite samples were made by replacing 1%, 2%, and 3% of the weight of quartz sand as the fine aggregate with OEB (fine and coarse). The hardened composites were further tested to determine their compressive strength, and it was found that the replacement of sand with OEB led to a decrease in compressive strength and flowability while alleviating the mortar’s density and affecting the setting time. The decrease in compressive strength was attributed to cavities present in the samples. Flexural tests and 28-day drying shrinkage measurements were carried out on the samples with 1% replacement of sand with OEB. The experiments showed that OEB fibers increased the flexural strength, functioned as a crack barrier, and reduced drying shrinkage.
