Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Conglomerate vs Sandstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Conglomerate vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Sandstone. Learn more about Conglomerate vs Sandstone in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Conglomerate and Sandstone, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Sandstone include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Conglomerate and Sandstone
Here you can know more about Conglomerate and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Sandstone consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Conglomerate is Shiny and Rounded and that of Sandstone is Rough. Properties of rock is another aspect for Conglomerate vs Sandstone. The hardness of Conglomerate is 2-3 and that of Sandstone is 6-7. The types of Conglomerate are Not Available whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Sandstone is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Sandstone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
