Rock that consists mostly of pebbles and larger size fragments is conglomerate; rock that consists mostly of sand-sized particles is sandstone; and rock that consists primarily of silt- or clay-sized particles is siltstone or shale, respectively. Of these rocks, hard, dense sandstone is the only type that generally is a source of crushed stone.Web

Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock.

Portland cement

Cement is made from gypsum, shale or clay, and limestone. The term "cement" is most often used to refer to Portland cement. Portland cement, when mixed with sand, gravel, and water, makes concrete, which is an essential element of the construction industry. Portland cement accounts for more than 95% of all cement produced.Web

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.Web

Sandstone is a sedimentary rock formed from cemented sand-sized clasts. The cement that binds the clasts can vary from clay minerals to calcite, silica or iron oxides.
