Abstract

The invention belongs to the technical field of solid waste resource utilization and particularly relates to a method for detecting the activity index of waste ceramic polishing sludge slurry. The method comprises a step of preparing a detected mortar test piece and a comparison mortar test piece, wherein the preparation raw materials of the detected mortar test piece comprise the waste ceramic polishing sludge slurry and first cement, the preparation raw materials of the comparison mortar test piece comprise second cement, the sum of the solid weight of the waste ceramic polishing sludge slurry and the weight of the first cement is equal to the weight of the second cement, and a water-binder ratio and a sand-binder ratio are respectively equal, a step of carrying out maintenance treatmenton the detected mortar test piece and the comparison mortar test piece, wherein the maintenance treatment comprises the following steps of removing molds of the prepared and molded test pieces and then sequentially carrying out maintenance in a heating stage, a constant-temperature stage and a cooling stage, a step of detecting the compressive strength of the maintained detected mortar test pieceand the comparison mortar test piece which are subjected to the maintenance treatment to respectively obtain a first compressive strength value and a second compressive strength value, and a step ofcalculating a ratio of the first compressive strength value to the second compressive strength value to obtain the activity index.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of solid waste, and in particular relates to a method for detecting the activity index of waste ceramic polishing sludge slurry. Background technique [0002] my country is a big country in the production and consumption of architectural ceramics. According to literature statistics, my country produces up to 10 million tons of ceramic polishing waste every year. Such a large amount of solid waste is very harmful to the environment and people, so the research on the reuse of ceramic waste is of great significance. At present, some people use ceramic waste to produce porous ceramics and add ceramic waste to the formula. However, this treatment method consumes a lot of energy, costs high, and has a small output and limited processing capacity, so it is not suitable for promotion and reference. Wan Dongmei and Peng Gang used ceramic waste to develop solid concrete materials, but this me...
