What does cement and sand make?
Sandstone.
What is the composition of sandstone?
Sandstone is usually composed of grains of quartz with a calcitic or silica based cement.
What are the 3 different types of cement bind together sand in sandstone?
Silica also called quartz cement, Calcite Cement, Iron Oxides also called hematite cement that bind sand together in sandstone. Sandstone also has other cementing agents that occur in less common forms. These cementing agents include pyrite, barite and gypsum.
What made the rocks in Australia red?
That is the original color of the rock - red sandstone. The sandstone has haematite cement in it which is naturally red
Sandstone is formed from tiny particles of sand cemented together Sandstone is?
Sandstone is a sedimentary rock. it is formed by the consolidation and compaction of sand and held together by a natural cement, such as silica.

What kind of cement produces bright-red and yellow colors in some sandstone?
Iron Oxide
What is the chemical formula for sandstone?
Sandstone has no defined chemical formula. Sandstone is usually composed of quartz grains sometimes cemented together with a variety of minerals. The quartz grains are composed of SiO2 (Silicon dioxide). The cement in a sandstone are often composed of quartz (SiO2) or calcite (CaCO3) or rarely, other minerals.
What is the cement of sedimentary rocks?
Sandstone is a sedimentary rock mainly composed of small sand size grains of quartz and/or feldspar. It is often used for construction and also to make items used in the house.
What Sedimentary rock is used in cement?
The sedimentary rock that is used in making cement is limestone. Cement, which is used in making concrete, is a mixture of marl and lime.
How might a sandstone change into another sandstone?
Sand that is overlayed by additional sediments will experience compaction. Small gaps between sand particles will fill in with minerals which cement the particles together. The process takes a long, long time.
What gives quartz sandstone its color?
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
