Analyzing the Characteristics of Self-Compacting, Basalt Fiber, Ultra-High-Performance Concrete Using Nanowaste Product at Both High and Normal Temperature Changes

The ecology is significantly impacted when waste materials are used to produce sustainable concrete. From a different angle, knowing how high temperatures affect concrete can help to lessen the effects of fire on the environment and cut the cost of recovery. This research presents a methodical experimental inquiry using agricultural by-product materials, such as agricultural waste products, textile ash, and paddy husks ash as cementitious material, in order to build ecological ultra-high performance rebound fiber self-compacting concrete (UHPBF-SCC). The varied dosages of nanoparticles are mechanically created after heat treatment at 700 °C, the effectiveness of the concentrations was examined. This paper additionally investigates the behavior of UHPBF-SCC at higher temperatures of 300 °C and 600 °C. Investigations on the biological appearances, such as separation resistance, have been conducted, workability, and passing skills. Additionally examined were compressive strength, strength loss at high temperatures, mass loss, ultrasonic testing velocity, splitting, and flexural strength test. To reveal the microstructure of the mixtures, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDX) examination were carried out. Comparing the nanoparticle-containing samples to a controlled experiment, the mechanical and physical properties increase significantly by much more than 18% in strength properties, 32% in yield stress, and 28% in undergoing a transformation. During normal operating circumstances, SEM analysis revealed compacted sections with high bonded matrices and high ITZ, but at 300 °C and 600 °C, micro-crack development became apparent due to ettringite dissolution and the evaporation of capillaries and adsorbed moisture. With the use of nanomaterials, EDX analysis revealed significant Ca/Si.
