Sand Equivalent Test indicates relative proportions of undesirable clay like fines in aggregates and granular soils Test equipment is sold in complete kits or as individual components Test equipment is sold in complete kits or as individual componentsHowever this discussion is limited to using fine gradations of lightweight aggregate to modify a conventional concrete mix to obtain internal curing Fine lightweight aggregate is used because its small size allows a more uniform distribution of the water filled internal curing reservoirs in the concrete

Gravel Gravel is not only used for construction purposes but also for a variety of purposes like gardening etc Gravel is an aggregate of rounded or angular fragment of rocks and minerals According to unified classification system particle sizes ranging from 475mm to 762mm are categorized as gravel Gravels have a large bearing capacity1 Aggregate properties such as angularity fines content and fines plasticity 2 Aggregate layer compaction 3 The number of load pass It was also noted for subgrade IBVs of 3 or greater aggregate properties rather than subgrade characteristics and aggregate thickness are likely to

D 14 Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate sand equivalent value fines content granular soils 52 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate Standard Test Method for Sand Equivalent Value of Soils and Fine Why clay has porosity number greater than sand such as sand and gravel Clay and silt have finer particles and hence more surface area So porosity is more the porosity of the sand size material is commonly greater than the porosity of the clay size materials 175k Views View 13 Upvoters Answer requested by

Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here Natural sand is generally used as fine aggregate silt and clay are also come under this category The soft deposit consisting of sand silt and clay is termed as loam The purpose of the fine aggregate is to fill the voids in the ENGINEERING CLASSIFICATION AND DESCRIPTION OF SOIL General Application Soil investigations conducted for engineering purposes that use test pits trenches auger and drill holes or other GW GC Well graded gravel with clay if fines = CL ML Well graded gravel with silty clay GP GM Poorly graded gravel with silt

Clay present on the surface of the aggregate particles in the coating form interfere with the bond between aggregate and the cement paste adversely affecting the strength and durability of concrete Other fine materials which may be present in aggregate are silt 2 to 60 181 m and crusher dustSilt and Clay are considered to be smaller family members of soil group Even small amounts of fines can have significant effects on the engineering properties of soils If as little as 10 percent of the particles in sand and gravel are smaller than the No200 sieve size the soil can be virtually impervious especially when the coarse grains are well graded

A sieve analysis or gradation test is a practice or procedure used commonly used in civil engineering to assess the particle size distribution also called gradation of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole massA3 Features of soil A31 Vegetable SOILpak Chapter A3 Features of soil proportions of gravel coarse sand fine sand silt and clay in the soil Texture is important because it affects the movement and availability A deep sandy soil like this allows plant roots to penetrate easily
