5.2 The sodium sulfate or magnesium sulfate soundness test is one method by which to estimate qualitatively the durability of rock under weathering conditions. This test method was developed to be used in conjunction with additional test methods listed in Practice D4992.This test method does not provide an absolute value, but rather an indication of the resistance to freezing and thawing ...

Name that rock! Look at all the data you've collected. Use the Guide Book to compare the results and find which type of rock you have! See what category the specific type falls under (igneous, metamorphic, etc.) and imagine how it was formed. A few tips to help you out: Every type of mineral has a specific rating on the Mohs Scale of Hardness.

The durability of rock depends on a number of factor, but the most influential factor is the rock's mineral composition. Minerals are all rated on the Mohs Hardness scale from 1 to 10, where 1 is a soft mineral like talc, and 10 is diamond. The mo...

1. Igneous Rocks. The first type of rock on this list are the igneous type of rocks. Igneous rocks are more than just a cool name. They're actually cool in another way. Igneous rocks are actually cooled and hardened magma. That means that Igneous rocks are formed when molten rock from deep within the earth rises to the surface (lava) and cools.

You may have heard of the Mohs scale, which ranks gem and mineral hardness on a scale of 1 (least hard – talc) to 10 (hardest of all – diamond). But hardness is only one factor in determining gem durability. Gemologists define durability as a gemstone's ability to withstand wear, heat, light, chemicals, and low or high humidity.

Peter A. Claisse, in Transport Properties of Concrete, 2014. 13.5.3 Discussion. For modelling concrete durability, it has been noted that neither the simple diffusion test nor the durability models take account of ion–ion interactions.It may also be seen that the simple diffusion test has a good resemblance to the geometry of an exposed concrete surface on site.
