“…In contrast to the behaviour observed during the compressive strength testing, the M3 and M4 samples with 0.25% and 0.30% PP fibres exhibited higher flexural strength than the control sample M1. Similar behaviour was also reported by [4]. In the interfacial zone, the micro-cracks are initially developed when the concrete is subjected to tensile stresses.…”

“…al. [4] reinforced concrete with two different PP fibre lengths (12.7 mm and 25.4 mm) and three different contents (0.20%, 0.25% and 0.30%). It was found that fibre length had a significant influence on the properties of concrete.…”

“…Still, this self-weight with the reinforcement steel bars exponentially increases, causing increased permanent load on the structures. The steel bars are prone to corrosion; once the corrosion occurs, concrete can be severely damaged from within [4]. Reinforcing concrete with more sustainable material than steel bars has become essential.…”

Concrete is the most used building and construction material globally due to the ease of availability and durability. It is a well-known fact that concrete can easily withstand compressive stresses; however, it fails under tension. To improve this deficiency, steel bar reinforcement has been used. However, with the steel reinforcement, additional permanent self-weight is transferred on the structure and is prone to corrosion. Hence, engineers and researchers have been working to search for more sustainable reinforcing material that could be cost-effective and simultaneously increase tensile strength. This experimental work was carried out to study the influence of long (38.1 mm) polypropylene (PP) fibres on the workability and mechanical strengths (compressive and flexural) of concrete. Three different fibre fraction content, 0.20%, 0.25% and 0.30% were selected to reinforce concrete. A total of 12 cylinders of 300mm×150mm dimension (3 cylinders per mix) and 12 beams of 609.6mm×304.8mm×101.6mm dimension (3 beams per mix) were used to determine the compressive strength and flexural strength after the samples achieved 28 days curing. Based on the results, it can be observed that longer fibres do not significantly influence the compressive strength as much as they do on flexural strength. Furthermore, longer length fibres, like shorter fibres, obstruct the workability of concrete. Comparing with previous findings, it can be concluded that for patching of macrocracks, longer length PP fibres should be used.

“…Many researchers have done the study of enhancement of the properties of LFC by the inclusion of short fibres such as sisal fibres [14], kenaf fibres [15][16][17], oil palm fibres [15,18], polypropylene fibres [15,16], and AR-glass and steel fibres [15]. However, some of the materials have a negative impact on the long-term performance of LFC such as deterioration of natural fibre [19], and corrosion of the reinforcing steel [20]. Thus, in this research, authors have explored the potentiality of continuous fibres, namely, fibremesh, as an enhancement to the properties of LFC, this has not being practiced yet in such types of concrete.…”

This research project was designed to investigate the influence of fibremesh on the durability properties of lightweight foamcrete (LFC). The fibremesh, categorized as a synthetic fibre (man-made fibre), was used for this study. It poses a continuous fibre with warp and weft structure that was used as confinement material in this investigation where four different weights per area (g/m2) of the fibremesh were observed namely, 110 g, 130 g, 145 g, and 160 g. Three experimental tests were involved in this preliminary study: porosity, water absorption, and drying shrinkage test. All the specimens were confined with 1-layer fibremesh at a constant density of 1100kg/m3 of LFC and the result was compared with the control (unconfined LFC). The 160 g/m2 of fibremesh significantly improved the physical properties of LFC where 13.8%, 20%, and 57.4% enhancement was obtained for the porosity, water absorption, and drying shrinkage result, respectively. ABSTRAK: Projek penyelidikan ini dijalankan bagi menyiasat kesan pengunaan jejaring sabut pada sifat ketahanan konkrit ringan berbusa (LFC). Jejaring sabut yang digunakan dalam kajian ini adalah jejaring gentian kaca tahan-alkali yang dikategorikan sebagai serat sintetik yang juga dikenali sebagai fabrik tekstil. Ia mempunyai serat yang panjang dan bersambung dengan struktur yang lekuk dan renda yang digunakan sebagai penambahbaikan bagi konkrit ringan berbusa. Terdapat empat berat jejaring sabut yang diuji iaitu 110 g, 130 g, 145 g, dan 160 g. Tiga jenis eksperimen bagi kajian awal ini iaitu keliangan, penyerapan air, dan pengecutan pengeringan. Semua spesimen dibalut dengan 1 lapisan jejaring sabut pada 1100kg/m3 LFC dan data yang diperoleh dibandingkan dengan spesimen yang tidak dibalut dengan gentian kaca berjejaring. Jejaring sabut 160 g/m2 meningkatkan sifat fizikal konkrit ringan berbusa di mana 13.8%, 20%, dan 57.4% peningkatan diperoleh bagi keliangan, penyerapan air, dan pengecutan pengeringan, masing-masing.

“…Most of the concrete's infrastructures is constructed using concrete, which is the most preferred construction and building material in the construction industry . The popularity of concrete has increased due to its availability, flexibility and durability (Memon et al, 2018), that is why concrete has been utilized in vast civil engineering applications ranging from the construction of foundations, retaining walls to bridges and dams (Sandhu et al, 2019).…”

Concrete is the most preferred building material in the world and its production has increased exponentially with the rapid construction of infrastructures. The generation of waste materials has also increased due to rapid urbanization. Eggshell is one such solid waste material which is being generated in huge quantity due to it being a cheap source of nutrition. Cement, the vital ingredient of concrete has been reported to contribute approximately 7% of total global Carbon Dioxide (CO2) gas emissions. This experimental study was carried out to study the workability and compressive strength of M40 grade concrete incorporating Eggshell Powder (ESP) as supplementary cementitious material, to reduce the cement content in concrete. ESP was ground into two fineness (50 um and 100 um) and three different percentages (5%, 10% and 15% by weight of cement) of ESP was used to replace cement content. It was observed that partial cement replacement using ESP was successful in achieving higher strength compared to the control sample. It was determined that 10% ESP was optimum, where the highest compressive strength was achieved. Furthermore, the fineness of ESP also had an influence on the compressive strength, the ESP which passed 50 um resulted in better strength. The optimum ESP to be utilized was determined to be 10% in both fineness.
