[Henry Cavendish] fixed the weight of the earth; he established the proportions of the constituents of the air; he occupied himself with the quantitative study of the laws of heat; and lastly, he demonstrated the nature of water and determined its volumetric composition. Earth, air, fire, ...
water and alcohol but soluble in concentrated acids. it is odourless. barium sulphate is an alkaline, divalent metal. it is non-toxic and safe for medical use. it is widely used in the production of oil and natural gas to get high-density drilling fluids by keeping the boreholes free of...
ash fluidized lightweight soil. Thus, the sum of𝑈𝑒Ueand𝑈𝑑Udequals the total energy𝑈U, with energy density measured in J/m2. Since only axial stress performs work in uniaxial loading, the energy calculation formula for uniaxial compression tests can be represented as follows [25]...
HSWIM (high speed weight-in-motion) systems enable measurement of a mass of vehicles passing through a measurement station without disturbing the traffic flow. This article focuses on the calibration of a weighing station for moving vehicles, where strain gauge sensors are used to measure pressures...
The impact of the hammer generates a stress wave in the hammering head that propagates towards the tip to drive the rod into the soil. The penetration (e, mm) and the cone resistance (𝑞𝑑qd, MPa) for each blow are continuously recorded using the Dutch formula [25,26,27,28], assu...
Foamed lightweight concrete is a lightweight cement-based material formed by preparing an aqueous solution of foaming agent into foam; mixing it with water, cement, additives, and other materials at a specific ratio; and hardening it. The preparation is shown in Figure 1. The transformation of...

Density is an important physical parameter of EPS beads mixed cement-reinforced clay or lightweight clay. The lightweight clay is composed of EPS beads, cement, water and marine clay and can be used as a bulk filling material in construction or geotechnical engineering. Cement-reinforced clay (...
