2030 STANDARD SAND ASTM C778 Cement testing standard specifications for standard sand . CHARACTERISTICS. 2030 sand is made of local natural silica sand (silica content 99 %), having a water content lower than %.
Specifications of standard sand 1 CHARACTERISTICS 2030 sand is made of local (French Source) natural silica sand (silica content 99 %), having a water content lower than %. The constituent grains of this sand are uncrushed and of rounded form. The sand is used for testing hydraulic cement in accordance with ASTM C 185 and C 190.

problems concerning premature sand clogging and failures with ASTM C33 sand as the filter media, revisions were made to the Recommended Standards and Guidance (RSG) for Intermittent Sand filters in 2000. The revised RSG began to allow the use of a coarser sand media specification that is more clogresistant than the ASTM C33 sand specification.
Note: Silica sand is typically characterized by its roundness of grains and produces a slower rate of abrasion on organic coatings. It has been noted that for 3 mil dry film thickness, many of the older coatings would require 20 to 200 liters of silica sand to achieve a failure.
Due to the complexity of silica chemistry, the form of silica measured is defined by the analytical method as molybdatereactive silica. Those forms of silica that are molybdatereactive include dissolved simple silicates, monomeric silica and silicic acid, and an undetermined fraction of polymeric silica.

Spent foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins) and dust. Table 72 lists the chemical composition of a typical sample of spent foundry sand as determined by xray fluorescence. Silica sand is hydrophilic and consequently attracts water to its surface.
