چکیده
The theme of this initiative is "Waste to Wealth." Construction materials, particularly concrete, need have better qualities, including strength, rigidity, durability, and ductility, because Oman's construction industry expanding. Self-compacting concrete (SCC) has more benefits than regular workability. major focus study the C30-grade SCC for control mix, spent catalyst (zeolite catalyst)-based SCC, development RC beam's flexural behavior employing catalyst-based SCC. preliminary main are two outcomes included in project. Preliminary research involves creating four mixtures with various dosages 3%, 6%, 9%, 12% order optimize C30 grade concrete. All cubes undergo a 28-day curing test. cubes' compressive strength tested establish ideal dosage, which 9%. Develop modified design mix accordance chemical admixtures such as superplasticizer (SP) at different dosages, like 2, 2.5, 3, 3.5%, using trials tests (slump flow, L-box, J-ring, V-funnel, U-box tests), well optimized dosage (SC). includes six singly reinforced beams dimensions 750 (L)×100 (B)×150 mm (D) that were cast laboratory. After period, specimens placed under two-point loading setup, remaining samples receiving optimum superplasticizer. Universal Testing Machine (UTM) 1000 kN capability. From study, partial substitution cement (SC), it was found 9% produces greater compared other doses, almost 10% rises 28 days period. Based on test, discovered dose 3% SP gave closer agreement satisfied per BS standard. load-carrying capability 21.7% higher beams. Comparing beams, their deflection reduced by about 26% same load level, ductility rose 33%. Comparatively beam, stiffness 21.6% also rises. According test results, beam performs every way when used recommended dosage. Doi: 10.28991/CEJ-2023-09-05-08 Full Text: PDF
