2021-3-7  Sieve size describes the minimum and maximum mesh sieves each grain of sand (each piece of Envirofill infill) would fit through. The “12” in the 12-20 size is the largest hole in the sieve that product would fit through. “20” is the smallest hole in the sieve that product would fit through.

Sand Dunes Coastal Care

The size of a dune is mainly a function of sand supply: the larger the supply from the beach, the higher the dunes. Prevailing wind directions, beach width and time available to build a dune are part of the sand supply picture.

2021-3-12  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.

effect of grain size and cement content on index

The samples were prepared by mixing the sand portions of the selected grain size distributions with cement and water. As displayed in figure 1, in this study five different grain size distributions were used. For each grain size distribution, three different cement content of 15%, 20%, and 25% were used.

Physical and Compaction Properties of Granular

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. Particle size distribution (PSD) has a great
