When a cylindrical object is subjected to a twisting force, it experiences torsion. The torsional modulus of elasticity, also known as the shear modulus or modulus of rigidity, is a measure of a material’s resistance to twisting and shear deformation under torsional stress. This key material property is essential for engineers and researchers working with…
Sieve analysis is a crucial process in determining the particle size distribution of coarse aggregates used in construction projects. The IS code for sieve analysis of coarse aggregate is IS 2386. The Indian Standard (IS) code provides guidelines for conducting sieve analysis to ensure consistent and accurate results. Importance of Sieve Analysis Coarse aggregates, such…
Air Meters for concrete measure the air content of fresh concrete in accordance with ASTM and AASHTO standards test methods. Gilson offers a selection of air meters for concrete for use in testing fresh concrete specimens or concrete mixes, lightweight aggregate concrete, or other lightweight mixes. Measuring the air content of fresh concrete is a critical…
Sieve shakers are devices designed to help promote particle movement through a stack of sieves, facilitating accurate particle separation. As the particle separate, they are retained on the various sieves depending on their size, providing insight into the average particle size of your sample. Sieve analysis is a long trusted method for accurately determining particle size…
Steel tensile test provides key data on strength, ductility, and additional mechanical properties for structural design and quality control. Steel is one of the most widely used construction materials in buildings, vehicles, infrastructure, and machinery due to its immense strength and durability properties. Steel exhibits immense strength thanks to advanced production methods. However, validating mechanical…
Elastic materials are substances that can stretch or deform when a force is applied, but then return to their original shape once the force is removed. These materials have the useful property of elasticity, which enables them to undergo reversible deformation. Some common examples of elastic materials include rubber bands, bungee cords, stretchy fabrics like…
