contact usSandstone. Composed mostly of quartz, sandstone is a durable material. However, it does have its drawbacks. Sandstone naturally forms from sand grains that have been cemented together by clay, calcite, or silicate minerals. But since this natural cement doesn''t fill all the voids between the sand grains, sandstone is porous.
contact us· Polymineral glacial gravel aggregates, 0/16 mm, from the northern regions of Poland were used. Fig. 1 shows the results of the X-ray analysis. The aggregates tested contain large amounts of quartz, calcite and plagioclase series with albite and anorthite, and lower amounts of clay minerals (illite, kaolinite) and dolomite.

contact usAggregates are inert granular materials such as sand, gravel, or crushed stone. divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter.
