Extensive research has focused on producing sustainable concrete by exploring waste and recycled materials as alternatives to virgin substances. However, waste-based concretes often exhibit inferior durability mechanical performance compared traditional concrete. Incorporating reinforcement agents can enhance their performance. This study investigates the use of sugarcane fiber a in containing fly ash (FA), ground granulated blast furnace slag (GGBS), fine coarse aggregates (RFA RCA). Five dosages fibers (0 %, 1 2 3 4 % mass) were examined. Mechanical tests, including compressive strength, flexural water absorption, chloride ion penetration, conducted. Scanning electron microscopy micro-porosity analysis employed for further assessment. Results show that adding enhances properties, with being optimal dosage. dosage improves strength 16 35 load bearing capacity 34 energy absorption 107 toughness index 6 while reducing penetration 23 %. Further increases decrease properties. The enhanced behavior is attributed reduced porosity, refined pore structure, microcrack propagation. underscores potential incorporating along develop eco-friendly composites, aiming mitigate carbon dioxide emissions address environmental concerns.

Straw fibers are renowned for their cost-effectiveness, sustainability, and durability. They represent a promising natural reinforcement option reactive powder concrete (RPC). This paper investigated the impact of straw on RPC’s workability, mechanical performance (mechanical strength flexural toughness), electrical properties (electrical resistance AC impedance spectroscopy curves). The fiber volumes ranged from 1% to 4.0% total RPC volume. Specimens were cured under standard curing conditions 3, 7, 14, 28 days. Mechanical specimens tested before chloride salt erosion. mass loss ultrasonic velocity samples measured NaCl freeze–thaw cycles (F-Cs). loss, strengths dry–wet alternations (D-As). findings indicated that incorporating enhanced strength, compressive toughness by 21.3% 45.76%, −7.16% 11.62%, 2.4% 32.7%, respectively, following 28-day period. addition could augment 10.17% 58.1%. characteristics adhered series conduction models. A power function relationship existed between RPC. After 10 D-As, rate, rates decreased 0.42% 1.68%, 2.69% 6.73%, 9.6% 35.65%, 5.41% 34.88%, compared blank samples. undergoing 200 F-Cs, 0.89% 1.01% 6.68% 8.9%, respectively.

Cement production is a major contributor to global CO2 emissions, necessitating the development of sustainable alternatives such as fiber-reinforced concrete incorporating supplementary cementing materials (SCMs) and agricultural waste. This approach keeps environment safe by reducing consumption conventional raw for production. Incorporating SCMs in can potentially improve mechanical durability properties. research evaluated behavior mixtures using different proportions natural wheat straw fiber, bentonite, silica fume (SF). The fresh property was investigated workability test, properties were compressive strength split tensile strength. Bulk density, water absorption, sorptivity tests also performed investigate concrete. Scanning electron microscopy (SEM) conducted evaluate microstructure morphology developed mixtures. results revealed that slump value decreased with fibers (83-42 mm). ranged from 11 MPa 23 MPa, increasing increased Bentonite SF dosages. Splitting 2.2 2.7 showing an increase dosages fibers. addition WSFR compromised strengths mixtures, however, ductility improved incorporation WSFR. SEM confirmed CSH gel formation containing bentonite SF. concrete, reduced its resistance acid. resulting address carbon emissions associated cement provide construction material.
