Abstract
The invention relates to a concrete water content detection device and method and a water content adjustment method based on the device. The detection device part mainly includes a concrete container; a plurality of acoustic wave receivers are arranged on the side wall of the concrete container, and an acoustic wave transmitter is arranged inside the container; all the acoustic wave receivers and the acoustic wave transmitter are connected with the same frequency measuring instrument ; The sound wave is emitted from the sound wave transmitter and penetrates the uncured concrete, and is received by the sound wave receiver and transmitted to the frequency measuring instrument. The device can be used to judge the water content of the concrete at the construction site and adjust it to a qualified range, thereby essentially ensuring the qualified quality of the building.
Description
technical field [0001] The invention relates to the relevant technical field of construction engineering equipment, in particular to a concrete water content detection device and method and a water content adjustment method based on the device. Background technique [0002] Concrete is the most common construction material in civil engineering construction. It has a wide range of uses and plays an important role in the construction of buildings and the like. Checking the water content of concrete is one of the most important links before the concrete is transported by tank truck to the site and begins to pour. [0003] If the water content is low, the viscosity of the concrete will lead to a decrease in fluidity, and uneven vibration will cause more air bubbles in the later-formed structure, which needs to be treated with water; if the water content is high, the concrete will take longer to solidify. Coarse aggregate will be distributed under the structure under the influen...
