“…Firstly, the presence of POF groups acts as a bridge between cracks, enhancing the cohesion of the specimens and impeding crack growth, thereby improving the tensile strength. Same effect has been observed in a previous study by Arash Sedaghatdoost et al (2017), where the addition of POF to concrete resulted in improved TS due to the bridging effect of POF groups [11].…”

Fly ash-based light-transmitting concrete (FLTC) is an innovative and energy-efficient construction material known for its superior characteristics. FLTC is a high-quality translucent concrete that offers excellent mechanical properties, and effective light transmission. This research study aimed to evaluate the performance of FLTC by incorporating plastic optical fibers (POF) and replacing a portion of the cement with fly ash. The investigation focused on assessing the mechanical properties and light transmittance capabilities of FLTC. Seven different concrete mixes of M20 grade were prepared, varying the volume of POF from 0.5% to 4% and replacing 25% of the cement with fly ash. After 28 days of curing, tests were conducted to measure compressive strength, splitting tensile strength, and light transmittance. The mechanical properties of FLTC demonstrated improvement with increasing POF volume ratios, while the light transmittance notably increased with higher POF volume ratios. FLTC achieved a remarkable light transmittance of up to 5.48% for specimens containing 4% POF volume ratio and 0.75 mm POF diameter, while still maintaining good mechanical properties. Additionally, FLTC exhibited an increase in compressive strength by 27.3 MPa, a tensile strength increases of 17.8%, and an upv value (ultrasonic pulse velocity) of 3.41 km/s.

“…It can be analyzed from Figure 9 that the LT Ratio increased with the increase in the percentage of POF. Previous research also shows the same trend for this test [13,14,15]. Figure 5 gives the details of the light passing through POF, and Table 6 describes the values obtained from the instrument.…”

“…Whilst, it is still being highly resistant to several durability problems that traditional concrete could cause [3]. Many efforts were applied toward developing high performance concrete for the building structures with enhanced performance and safety [4]. Geopolymers are the product of alkali activated aluminosilicate sources that excelled as an alternative to ordinary binders due to its sustainability, low cost and good mechanical properties [2].…”

Geopolymer paste is an innovative construction material which shall be produced by chemical action of inorganic molecules. It is a more environmentally friendly alternative to conventional Portland cement which is abundantly available worldwide. In this study, the influence of different alkaline activators (Na and K) on the mechanical and thermal behaviors of metakaolin-based geopolymer was investigated. The aims of this study is to find out the mixes and their process parameters, which are appropriate to produce Geopolymer paste with one of the highest compressive strength, highest-lowest porosity and highestlowest initial and final setting time. Taguchi method is used in the design of the experiments for the metakaolin-based Geopolymer. Five factors were selected as process parameters that are more likely to affect the Geopolymer characteristics. These are the amount of Si, alkali type, alkali reagents ratio, mixing time, and water content. The effect of these parameters on the setting time, density, porosity, compressive strengths at 7 and 28 days. The results of study found that the Geopolymer paste with high compressive strength of (107.2MPa) can be obtained with the formula (0.2K2O.0.8Na2O. Al2O3. 3.6SiO2.xH2O) using proper processing condition in which the alkali silicates to the alkali hydroxides molar ratio should be kept in the range of 2.26. The results revealed that the use of alkali solution of Kions and Na-ions improves the compressive strength of the geopolymer remarkably as compared with the use of Na-ions solution along. In addition, it has been noticed that the setting time is reduced, for geopolymers with silica content of less than 3.8, when K-ions is used. Similarly, the bulk density of geopolymers is found to be reduced by adding K-ions.

“…Dengan penambahan serat aluminium variasi 0,5% , beton ringan foam berserat mengalami peningkatan baik kuat tekan, kuat tarik belah maupun modulus elastisitasnya. Potensi meningkatkan sifat beton juga diperoleh dari pemanfaatan serat poliolefin ke dalam beton dengan mengubah sifat antarmuka serat-matriks, Sedaghatdoost (2017). Penguatan dengan serat alami pada beton ringan juga telah banyak dilakukan oleh para peneliti diantaranya serat ijuk oleh Perdana dkk.…”

Cellular lightweight concrete has an advantage in its specific gravity, with the presence of foam making it lighter. However, the presence of foam reduces its strength. Utilization of used clothing fibers is carried out to increase the flexural strength of cellular lightweight concrete and is useful for reducing environmental loads. Used clothing fibers are added to the cellular lightweight concrete in the amount of 0%; 0.3%; 0.6%; 0.9% and 1.2% of weight. Cellular lightweight concrete is also reinforced with steel wire mesh with a wire diameter of 0.5 mm with a side length of ¼ inch x ¼ inch. With the addition of used clothing fibers increase the flexural strength and reduce the density of cellular lightweight concrete. The addition of steel wire mesh increases the flexural strength but increases the density of cellular lightweight concrete.
