[0002] Concrete is abbreviated as concrete, which is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in construction projects. Concrete needs to undergo some experimental tests before construction. It is necessary to first test the strength of a part of the concrete after solidification. Large-scale construction can only be carried out after the strength of the concrete is qualified. Most of the concrete strength detectors on the market cannot guarantee the accuracy of the test when testing the strength of part of the concrete due to the uneven surface of the concrete.
