ASTM C70

ASTM C70 is a standard set by ASTM International that outlines how to test concrete and cement paste for their ability to absorb water. This test evaluates the porosity of these materials, which is important for understanding their durability and performance in construction. By measuring how much water is absorbed, builders can assess how well the material will hold up against weather, moisture, and other environmental factors. This is crucial for ensuring the longevity and integrity of structures made from concrete or cement.
