Introduction. Over the past decade, technology and research have greatly expanded the functionality and aesthetics of prosthetic feet. Today, amputees have a wide array of feet from which to choose. Various models are designed for activities ranging from walking, dancing and running to cycling, golfing, swimming and even snow skiing.

Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.

This paper studies the early mechanical properties of artificial sand concrete, we found by comparison with natural sand concrete that the slump of artificial sand concrete were increased by 85%, and the strength 0f 16h and 1d and3d were increased by 23.4% and 20% and 11%. Therefore, artificial sand can significantly improve the workability of concrete mix, improve …

Abstract To investigate the static-dynamic coupling mechanical property of artificial frozen silty clay at high strain rates, the dynamic triaxial compression tests on artificial frozen silty clay at −10 °C were conducted with the help of modified triaxial SHPB system. The variations in strain rate, active confining pressure, and axial pre-compressive stress ratio with coupled static and ...

strength of concrete by partial replacement of artificial sand by foundry sand as fine aggregate. Tests were carried out on cubes, cylinders and unreinforced beams to study the mechanical properties of concrete using foundry sand and compared with concrete with artificial sand as fine aggregate. Artificial sand was replaced with five percentage ...

Sand particles pass a 425-µm sieve and are retained on a 75-µm (No. 200) sieve. Fines are soil particles that pass a 75-mm sieve; they are further characterized as silt or clay, based on their plasticity. a. Gravel and Sand. Gravel and sand have essentially the same basic engineering properties, differing mainly in degree.

Artificial cemented sand test samples were prepared by using ordinary Portland cement (OPC) as the cementing agent. Through uniaxial compression tests and consolidated drained triaxial compression tests, the stress-strain curves of the artificial cemented sand with different cementing agent contents (0.01, 0.03, 0.05 and 0.08) under various confining …

The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.

The artificial marble was evaluated their performance by water absorption, flexural strength, compression strength, and Barcol hardness properties. It was found that artificial marble prepared with 60% (wt.) of fine particle and 10% (wt.) of coarse particle showed the best overall properties leading to a lowest water absorption and good ...

Artificial turf is being used more and more often. It is more available than natural turf for use, requires much less maintenance and new products are able to comply with sport performance and athletes' safety. The purpose of this paper is to compare the mechanical and biomechanical responses of two …

Properties of Stone Silicious rocks are hard and durable.They are not easily affected by weathering actions. Argillaceous rocks may be dense and compact or they may be soft. The Durability of calareous rocks will depend upon the constituents present in surrounding atmosphere. Marble and quartzite have compact crystalline structure. Igneous rocks contain …

Since the amount of sand making machine is falling and more and more policies are set to protect the natural sand, the market for artificial sand (that is, sand and gravel aggregates processed by industrial sand making machines such as sand making machines and impact crushers) has shown great potential and vitality. Especially in recent years, the demand …

The changes in the mechanical properties of gas hydrate-bearing sediments (GHBS) induced by gas hydrate (GH) dissociation are essential to the evaluation of GH exploration and stratum instabilities.
