Method for testing effective penetration depth of concrete surface treatment material

An effective penetration depth testing method for a concrete surface treatment material belongs to the technical field of penetration depth testing methods. In order to eliminate the interference of alkaline substances in the concrete, a concrete carbonization accelerating method is adopted, so that a test piece for testing the concrete is completely carbonized, and then the test piece is put into a drying box to be dried. The heating temperature and the drying temperature in the accelerated carbonization process are both 38-42 DEG C, and carbonic acid can be decomposed at 28-36 DEG C under the standard atmospheric pressure, so that the temperature range of 38-42 DEG C avoids the influence of overhigh temperature on the concrete strength in the accelerated carbonization process, and also can eliminate the influence of residual carbonic acid in the concrete on the test result. A concrete surface treatment material is sprayed, a test piece is split after complete penetration, an acid-base indicator is dropped i
