Marble Test Water Stability

The marble test and the langelier index.

Marble test water stability.

Method of test for determination of true specific gravity of natural building stones. 13030 1991 astm c 97 2009. Langelier index l i langelier index ph ph s phs ph at which water having the same alkalinity and calcium content is just saturated with calcium carbonate. Method of test for determination of water absorption apparent specific gravity and porosity of natural building stones.

Both the langelier index and the marble test are laboratory tests which can determine the degree of calcium carbonate saturation in the water at the treatment plant. Perform a simple water test to see if your granite countertops need to be sealed. Pour a bit of water on the counter. The amount of water that refractory can absorb is measured by the water absorption test.

Note the time that you placed the water on the counter and time the water to see how long it takes to absorb the granite will darken. 1 4 cup should be enough. High concentrations of these metals in the water indicate corrosion in the distribution system although in a few cases the metals may have originated in the source water. The results of water absorption tests are used for quality assurance.

Testing for oil based marble staining. To conduct this part of the test follow these steps. The mineral oil should sit for. Take a small amount of mineral oil and use a cotton ball or something similar to dab it on your marble or granite.

This same test needs to be conducted for petroleum or oil based products you may use on a regular basis. Alkalinity lead and copper rule elements 1991 1.
