Normal-Weight Concrete with Improved Stress–Strain Characteristics Reinforced with Dispersed Coconut Fibers

According to the sustainable development concept, it is necessary solve issue of replacing fiber from synthetic materials with natural, environmentally friendly, and cheap-to-manufacture renewable resources agricultural waste. Concrete primary material for which fibers are intended. Therefore, use vegetable waste in concrete an essential urgent task. Coconut has attracted attention this matter, a by-product processing coconuts makes relevant. This work aims investigate experimental base strength properties dispersed fiber-reinforced coconut fibers, as well influence percentage on mechanical, physical, deformation characteristics. The samples were made compressive at 28 days 40 50 MPa. main mechanical characteristics such compression (cubic prismatic) tension (axial bending), material’s tensile strains, investigated. reinforcement was taken range 0% 2.5% increment 0.25 wt.%. Tests carried out after manufacture. microstructure resulting compositions investigating using electron microscopy method. most rational obtained 1.75%. increase indicators 24% 26% axial compression, respectively, 42% 43% bending tension, respectively. ultimate strains raised by 46% 51%. elastic modulus increased 16%.
