Rice straw is an agricultural waste that difficult to manage and has traditionally been burned or buried, leading environmental problems. Because of this, the introduction rice into concrete proposed revalue this residue. This investigation shows experimental work carried out prepare fibers introduce them a mix as macrofibers. In addition, three fiber treatments were compared: two alkaline one thermal. Four mixes studied: reference mix, with untreated in dosages, 10 kg/m3 15 kg/m3, fourth treated sodium hydroxide. The properties analyzed are workability, compression flexural strength, shrinkage. results show used improves strength at peak but does not provide post-crack residual strength. hydroxide treatment was effective obtaining more cohesive lower setting time delay slightly improved performance peak. summary, can be encapsulate material, providing enough for several engineering applications (>30 MPa).

Concrete is widely recognized as one of the most durable construction materials; however, it often exposed to harsh environmental conditions that can compromise its mechanical performance. This experimental study evaluated and compared properties fiber-reinforced concrete incorporating cornhusk fiber (CHF) glass (GF) under varying loads exposures. Three levels CHF (0.5%, 1.0%, 1.5% by mass cementitious material) an optimized GF dosage (0.1% volume concrete) were examined. cylinder specimens cast monitored for structural performance over 75 150 days two exposure conditions: laboratory-controlled (in-lab) natural outdoor environments. The assessed included compressive strength splitting tensile strength. findings indicated reinforced with 0.1% (GFRC) exhibited highest 28-day among all samples. Among CHF-reinforced (CHFRC) mixtures, 0.5% demonstrated superior other CHFRC mixtures. Over time, mixture consistently gains both in-lab conditions. In context testing, GFRC (0.1%) optimal at mark. However, samples, interval. At 150-day mark exposure, surpassed specimens, including GFRC, thereby underscoring remarkable long-term These underscore potential practical applications, offering balance durability strength, particularly prolonged stresses.

Plant fibers (PFs) have been increasingly employed in cement-based gel composites (CCs) on account of their excellent mechanical properties, toughness and sustainability. Researchers engaged a lot studies plant fiber-reinforced (PFRCCs). Based these studies, the chemical components characteristics PFs are summed up this review. In addition, modification methods for matrices also discussed. The properties PFRCCs, including static dynamic reviewed. Predictive equations PFRCCs summarized paper. end, interface transition zones between CCs analyzed. According to results previous addition can enhance flexural strength tensile CCs, but it an uncertain effect compressive strength. elastic modulus fracture behavior increases with PFs. At same time, proved be useful reducing degradation CCs. Generally speaking, new building materials which extensive application prospects. aim review is help researchers understand promote future projects.

The speed with which fashion trends change encourages excessive consumption and inadequate management of textile waste. Therefore, the use recycled cotton fibres (RCF), as a sustainable alternative, by industries has taken on greater relevance; however, there are uncertainties about its implementation appropriate method. this review aims to identify method blending produce new yarns. For this, PICO was used define research questions keywords; Then, it complemented PRISMA methodology search for information in Scopus ProQuest databases. found analyzed an Ishikawa diagram later Pareto diagram. Finally, concluded that most suitable RCF is 50% VCF RCF. If more RCFs were added, products would not meet optimal quality measures their production marketing. Likewise, main limitations implementing adequate selection type recycling, high financial outlay classification legal loopholes such lack supervision government, extended responsibility policy (EPR). Furthermore, specific regulations recycling absence certifications companies adopt practices represent additional obstacles.
