Performance of Solid Masonry Blocks Incorporating Rice Husk Ash Produced Under Open and Controlled Burning Conditions
The construction sector is responsible for a significant share of global CO₂ emissions, primarily from Portland cement production. Rice husk ash (RHA), an agro-industrial by-product rich in amorphous silica, offers a promising pozzolanic substitute for cement. This study evaluates the mechanical and durability performance of solid masonry blocks (215 mm × 105 mm × 65 …
Footsteps – A Review of Train Approach, Speed, Direction, and Distance Detection Methods Using Vibrations
Train detection is fundamental to railway signaling and safety, traditionally relying on infrastructure-heavy systems such as track circuits and axle counters. While reliable, these methods involve significant maintenance and are often limited in remote areas. This paper provides a comprehensive review of emerging vibration-based sensing techniques, which utilize accelerometers and geophones to capture distinct vibration …
Footstep Based Piezoelectric Energy Harvesting System for Emergency Power Applications – A Review
The conversion of mechanical energy from vibrations or pressure to electrical energy is called piezoelectric energy harvesting. In the context of densely populated areas like railway stations, shopping malls, airports and underground transportation systems, the piezoelectric floor tiles have become a sustainable method to harvest the energy of people walking on the floor. This technology …
Mechanical Testing of Materials Understanding Stress-Strain Relationships
Mechanical testing plays a critical role in the selection of materials by providing insights into their strengths and weaknesses. This paper examines the relationship between stress and strain, emphasizing fundamental concepts for analyzing material failures. While the uniaxial tensile test is the most widely used method for determining key properties such as stiffness and strength, …
