What is the hardness and luster of limestone?
limestone's hardness is 3-4 and it does not have a luster it's main constituent is the mineral calcite, and has a vitreous or glass luster.
How hard is Limestone?
the hardness of it is 3 - 4
What is the physical appearance of chalk?
Since limestone is predominantly composed of calcium carbonate (CaCO3), it is soluble in acid (or when crushed soluble in water) and is an alkali. Also it makes good lime for the garden, when heated properly it makes good portland for concrete, and is used in toothpaste and antacids. For information on the material properties of limestone, such as strength, stiffness and density, please see the related questions.
How does limestone increase the hardness and adjust the PH of water?
In very simple terms. Limestone is an alkaline and when it comes into contact with water, alkaline molecules/components are formed and these buffer/ bind with some of the acid molecules/components and thus cancel them out reducing the acidity (increasing the alkalinity) of the water.
How does marble differ from limestone there than color?
Hardness, Elasticity, Porosity, Permeability, Density, resistance to diagenesis, conditions of formation. Generalities (this means that in general the following are true and rules don't follow the exception if any exist) Hardness: marble is harder than limestone. It has a higher compressive strength and cohesion. This can get much more technical so let's leave it at that. Elasticity: Young's Modulus, shear modulus of marble is higher. Bulk modulus and poisson's ratio of marble is lower. Porosity of marble is lower. Permeability of marble is lower. Density of marble is higher. Limestone is often altered via fluids and chemical underground and marble isn't. Marble is metamorphic rock and limestone in sedimentary. Marble and Limestone are spelled different.
What can scratch Limestone?
Anything higher on the hardness scale for example if limestone has a hardness of 4 then it would take something with a hardness of 4 or higher to scratch it.
What is the mohs hardness of scale of limestone?
The hardness is 3-4 on Mohs scale.
What is the hardness and luster of limestone?
limestone's hardness is 3-4 and it does not have a luster it's main constituent is the mineral calcite, and has a vitreous or glass luster.
How hard is Limestone?
the hardness of it is 3 - 4
What is the hardness range for al 6061-t6 alloy?
38,000 PSI 38,000 PSI
Brinell hardness of 300HB in psi and Mpa?
300 mpa
What is the hardness of dolomite on the MOHS hardness scale?
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
Is dolomitic limestone same as agricultural limestone or horticultural hydrated limestone?
dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.
How do you get limestone out of your pipes?
You don't. Treat water to help with water hardness. If pipes are clogged, replace them.
How hard is hardwood floors?
The hardness of the wood will depend on the species of hardwood. The Janka scale measures the hardness of species and red oak is the standard with hardness of 1,290 psi (pounds per square inch). You can see more on this in the attached link where it shows the hardness for many species.
Does limestone have luster?
Granite is not naturally shiny but it be polished to achieve a surface shine.
Limestone can be metamorphosed into?
Limestone can be metamorphosed into marble through the process of recrystallization under high pressure and temperature conditions. The calcite crystals in limestone are transformed into interlocking crystals of calcite or dolomite in marble, resulting in increased hardness and a distinctive pattern and coloration.
