Why does cement harden?
cement is a calcined mixture of limestone,silica and gypsum that are anhydrated and form a hard structural bond on drying
Why does acid rain affect limestone but not granite?
Limestone is composed of calcium carbonate, an alkaline substance that breaks down on contact with acid. Granite is composed primarily of silica and feldspar, which are not so basic and do not react with acid.
Which type of rock can be formed by chemical reactions?
limestone
Which type of rock is made of calcium carbonate?
limestone
What type of chemical weathering is associated with limestone?
Normal rain (slowly) and acid rain (rapidly) both weather limestone.
Is limestone a source of silica?
In pure form, limestone is calcium carbonate, and does not contain silica. However, in SOME strata of limestone, silica can be present as an impurity.
What are known Limestone health hazards?
Silica dust is dangerous.
What are small crystal-lined spheres of silica rock that sometimes occur in limestone called?
Small crystal-lined spheres of silica rock that sometimes occur in limestone are called geodes.
A cherty limestone would contain which major constituents?
silica, calcite
What are minerals found in uttar pradesh?
Coal, limestone, silica and Bauxite.
What is the constituents of hard glass?
the constituents of hard glass is potassium carbonate , limestone and silica
What are three natural cements?
1. Silica (quartz) 2. Calcite (limestone) 3. Clay
Is sandstone and limestone the samething?
No. Sandstone is mostly made of silica whereas limestone is made from calcium carbonate (which may contain some magnesium and other carbonates.
How can you extract fossils from limestone?
It depends on their size and chemical composition. Fossils closely akin to the limestone matrix in composition would need to be manually removed by use of dental tools, scrapers, or electric Dremel type tools. If the fossil has been replaced by silica, it could be removed by the application of acid to remove the limestone that surrounds it.
Is cement a mixture?
yes, of sand and water or technically limestone, silica, aluminates, feric minerals
What is added to limestone to make glass?
The main thing that is added to limestone is melted silica or sand. These two items react to create the end products of waste gas and glass.
What sedimentary rock forms inside of limestone?
One possible answer is that chert can form inside of limestone. Chert is a microcrystalline sedimentary rock that forms from the accumulation of silica-rich remains of marine organisms, such as diatoms or radiolarians. Another possibility is travertine, which is a type of limestone that forms from the precipitation of calcium carbonate from water, typically in caves or hot springs.
