It takes between 3200-3500 pounds of raw material to make one ton of cement, the bulk of the raw material being limestone. Let's say the ratio is 1.5 tons limestone for every 1.0 ton of cement.

How long does limestone take to form?
a seashell doesn't teachnally turn in to a limestone if it didit would take a lot of minerals and heat,pressure
Where does weathering take place the most?
Limestone in a warm wet climate.
How is it possible for weathering to take place beneath bedrock?
The potholes and caverns formed in limestone by water seeping through limestone bedrock is an example of such weathering.
What are the advantages with limestone quarrying?
The advantages of limestone quarrying are endless. It is readily avaible and very easy to cut into blocks. It is also very good in humid places as it is able to resist humidity very well. Furthermore, it is also very easy to cut and to sculpt so it is used a lot to make elaborate and difficult sculptures. So as you can see from these answers, there are many advantages of limestone quarrying and the limestone industry is very strong at present indeed. The advantages of limestone are that it is cheap and efficiant:)
How limestone rock are form?
Limestone is a sedimentary rock made up of calcite (CaCO3) as its main mineral. Some limestones were formed by chemical deposition and others by the accumulation of shells from minute sea creatures. Many invertebrate animals (animals with no backbones) take calcite from sea water to construct their shells. When they die the shells fall to the sea bed. Areas where there is little deposition of mud or sand will be ideal for the formation of limestone. One type of limestone which is very pure is called chalk, but most other limestones contain variable amounts of mud or sand or other material.

Does carbonic acid dissolve limestone?
No. It dissolves limestone slowly. It may take centuries for a limestone outcrop to show visible weathering.

What minerals are in cement?
The starting point is to bake limestone to remove the CO2, leaving CaO, and to this some diatomaceous earth is added. Diatomaceous earth is composed of the bodies of silica containing organisms, Diatoms, and they are very finely structured. (Otherwise they'd just use beach sand).And a little CaSO4, plaster of paris.So we have a mix of silicates and sulphates and calcium. And they will make many complex minerals.And the end result for the user is a complex mix of silicates and sulphates all of which take some time to form their crystals which is what makes cement and concrete strong. This is why it is vital that for high strength purposes, the concrete should be kept moist for a period - up to 28 days in some applications.In some applications, e.g. making concrete pipes and concrete blocks, rather than waiting for the product to gain strength just by setting, these products are steam heated to hurry along the crystal forming process.late addition. At this moment, proposals are afoot to make cement from Serpentine, which is a magnesium silicate. This is baked to produce MgO, and this is then substituted for the CaO in cement. This then reacts with the other components as usual. BUT does not produce the CO2 into the atmosphere that baking limestone does. AND, in service, the MgO cement will actually absorb some CO2 from the air!. Still produces some CO2 during the baking of course - but only one-half the quantity.
