More C In unsaturated concrete, the rate of ingress of water or other liquids is largely controlled by absorption due to capillary rise. Water absorption is also strongly affected by the moisture condition of the concrete at the time of testing. In general, the rate of absorption of concrete at the surface differs from the rate of absorption of a sample taken from the interior.

More C In unsaturated concrete, the rate of ingress of water or other liquids is largely controlled by absorption due to capillary rise. Water absorption is also strongly affected by the moisture condition of the concrete at the time of testing.

In general, the rate of absorption of concrete at the surface differs from the rate of absorption of a sample taken from the interior. The exterior surface is often subjected to less than intended curing and is exposed to the most potentially adverse conditions.

This test method is used to measure the water absorption rate of both the concrete surface and interior concrete.

By drilling a core and cutting it transversely at selected depths, the absorption can be evaluated at different distances from the exposed surface. The core is drilled vertically or horizontally.

In this test method, only one surface is exposed to water at room temperature while the other surfaces are sealed simulating water absorption in a member that is in contact with water on one side only. Test Method C , on the other hand, is used to estimate the maximum amount of water that can be absorbed by a dry specimen and therefore provides a measure of the total, water permeable pore space.

Scope 1. The specimen is conditioned in an environment at a standard relative humidity to induce a consistent moisture condition in the capillary pore system. The exposed surface of the specimen is immersed in water and water ingress of unsaturated concrete is dominated by capillary suction during initial contact with water.

No other units of measurement are included in this standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The specimen is conditioned in an environment at a standard relative humidity to induce a consistent moisture condition in the capillary pore system. The exposed surface of the specimen is immersed in water and water ingress of unsaturated concrete is dominated by capillary suction during initial contact with water. Print and complete the following order form. The test surfaces shall be at the same distance from the original aastm surface of the concrete.

Zulura When cores are taken, they should be marked so that the surface to be tested relative to the original location in the structure is asfm indicated. This test method is used to measure the water absorption rate of both the concrete surface and interior concrete. The average of test results on at least 2 specimens shall constitute the test result. The specimen is conditioned in an environment at a standard relative humidity to induce a qstm moisture condition in the capillary pore system. In unsaturated concrete, the rate of ingress of water or other liquids is largely controlled by absorption due to capillary rise. By drilling a core and cutting it transversely at selected depths, the absorption can be evaluated at different distances from the exposed surface.
