In recent years, with the vigorous development of the building industry in China, more and more wastewater and slurry are generated in construction, such as scrapped cement slurry caused by pumping construction pipe-wetting mortar and blocking pump interruption in construction engineering, and considerable amount of unset concrete mixture waste is inevitably generated by ready-mixed concrete production enterprises every day due to test, production and other reasons. The common practice is to separate sand, stones and wastewater slurry from concrete mixture waste through a sand-stone separator, the separated sand and stones can be directly used for producing concrete, and the separated wastewater slurry is not recycled well.
At present, many enterprises do not have large-scale waste slurry recycling facility equipment, only use waste water for producing concrete through the sedimentation tank, but the waste slurry of sediment can not be recycled, once the storage capacity of the sedimentation tank is exceeded, the waste slurry can only be cleaned and excavated, and the waste slurry is transported away through a transport vehicle, even some bad illegal transport vehicles steal and discharge the waste slurry, and the environment is seriously polluted. The method can be used for recycling the wastewater slurry and producing concrete, but the solid content is an important control index, and has certain influence on the strength and the mixing performance of the concrete. Therefore, how to quickly determine the solid content of the waste cement slurry is significant for the recycling efficiency and the design and adjustment of the mixing ratio.
Through investigation, the solid content detection of the wastewater slurry is usually a drying method, which is time-consuming and is not beneficial to real-time rapid monitoring; in addition, solid matter particles in the wastewater slurry have cohesive property due to a certain micropore structure, and in addition, the traditional detection method only estimates the solid content of the wastewater slurry by measuring the density of the wastewater slurry, and the influence of the cohesive water content of the solid matter in the wastewater slurry and the gas content of the wastewater slurry on the density of the wastewater slurry is not considered, so that larger test deviation is easy to occur, and the control of the quality of concrete is not facilitated.
