Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Conglomerate vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Limestone. Learn more about Conglomerate vs Limestone in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Conglomerate and Limestone, 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 Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Conglomerate and Limestone
Here you can know more about Conglomerate and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Limestone consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Limestone, 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, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Conglomerate is Shiny and Rounded and that of Limestone is Rough and Banded. Properties of rock is another aspect for Conglomerate vs Limestone. The hardness of Conglomerate is 2-3 and that of Limestone is 3-4. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Limestone is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
