EN , Testing hardened concrete — Part 2: Making and curing specimens for strength tests 3 Principle Water is applied under pressure to the surface of hardened concrete. The specimen is then split and the depth of penetration of the waterfront is measured. An example of a test arrangement is shown in Figure 1. NOTE 1 It is preferable that the apparatus should allow the other surfaces of the test specimen to be observed.

NOTE 2 The water pressure may be applied to the surface of the test specimen either from the bottom, or the top. A watertight seal shall be provided, made of rubber or other similar material. The dimensions of a test area shall be approximately half of the length of the edge or diameter of the test surface. Do not apply the water pressure to a trowelled surface of a specimen.

During the test, periodically observe the appearance of the surfaces of the test specimen not exposed to the water pressure to note the presence of water. If leakage is observed then consider the validity of the result and record the fact.

NOTE 6. Examination of specimen After the pressure has been applied for the specified time, remove the specimen from the apparatus. Wipe the face on which the water pressure was applied to remove excess water. Split the specimen in half, perpendicularly to the face on which the water pressure was applied. When splitting the specimen, and during the examination, place the face of the specimen exposed to the water pressure on the bottom.

As soon as the split face has dried to such an extent that the water penetration front can be clearly seen, mark the water front on the specimen. Measure the maximum depth of penetration under the test area and record it to the nearest mm.
