Aug 21, 2018· Manufactured sand equal to natural sand. Ever wondered about the economic and ecological benefits of manufactured sand and how it is equal to natural sand? Let me help you with a better understanding of its concept.
Overview. The sand equivalent test (Figure 1) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). The term sand equivalent expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic fines and dust (ASTM, 2003 [1] ).These materials can coat aggregate
The term sand equivalent expresses the concept that most granular soils and some fine aggregates are mixtures of desirable coarse particles, sand-size particles, and generally undesirable clay or plastic fines and dust.
The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is less claylike material in a sample.
Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material.

CALCULATIONS 5.1 Calculate the sand equivalent value to the nearest 0.1 in.: Sand Equivalent Value (SE) = 100 * (Sand Reading / Clay Reading) 6. REPORTING TEST RESULTS
Apr 30, 2011· Sand Equivalents. According to Caltrans' test method 217-Sand Equivalent, "The sand equivalent test provides a measure of the relative proportions of detrimental fine dust or clay-like material in soil or fine aggregates." Fine dust (#200s and smaller) and clay material in aggregates can be detrimental to the performance of hot mix asphalt for a variety of reasons.
Crushed Sand (Manufactured Sand) It is an eco-friendly material. It gives higher durability and strength to concrete by overcoming deficiencies like segregation, bleeding, honeycombing, voids and capillary. Uniformly graded aggregates are available. Higher cohesion and compressive strength.

Nov 13, 2017· To a geologist or mineralogist, silica only means a SiO2 compound, regardless of its actual crystal structure. If you had pure SiO2 glass, you could describe it as being made of silica, and you can say that chemically, pure quartz is also SiO2.
