Soil Properties and the Unified Soil Classification System

a. Gravel and Sand. Gravel and sand have essentially the same basic engineering properties, differing mainly in degree. The division of gravel and sand sizes by the 4.75-mm sieve is arbitrary and does not correspond to an abrupt change in properties. When devoid of fines, coarse-grained soils are pervious, easy to compact, and have little affect

Manufactured Sand (M

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.

Impact compression properties of artificial cemented sand

In order to explore the mechanical properties of rock with deep in-situ stress under explosive impact, cemented sand material (artificial material) instead of rock was used to carry out impact dynamics test under the condition of confining pressure. The experimental results show that the stress-strain curve of cemented sand specimens tested by triaxial impact compression changes significantly

Physical and Compaction Properties of Granular Materials

Granular materials in geotechnical engineering is generally considered to be mixtures of clay, sand, and gravel that commonly appear in slopes, valleys, or river beds, and they are especially used for the construction of earth-rock-filled dams. The complexity of the constitution of granular materials leads to the complexity of their properties.

Manufactured Sand vs. Natural Sand

Feb 12, 2015The 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.
