Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Limestone and Sandstone Properties
Know all about Limestone and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Sandstone belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Sandstone is Clastic, Granular, Rough. Limestone appears Rough and Banded and Sandstone appears Rough. The luster of Limestone is dull to pearly while that of Sandstone is dull. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, 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. The commercial uses of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
