Gravel fine particle material methylene blue rapid screening detection method

Abstract

The invention discloses a gravel fine particle material methylene blue rapid screening detection method. According to the method, a methylene blue solution is used for carrying out titration testing on a specific material source fine particle material sample, so that a detection quantity line equation and an acceptance range of the material source fine particle material are obtained and are used as the basis for subsequent acceptance inspection of the same material source fine particle material. Compared with the prior art, the gravel fine particle material methylene blue rapid screening detection method has the advantages that the operation time can be saved and the workload of constructors is reduced; meanwhile, feeding components can also be roughly analyzed and are used as the basis for adding a subsequent interface active agent.

Description

technical field [0001] The invention relates to a quick screening method for fine sand and gravel materials, in particular to a quick screening method for methylene blue quick screening for sand and gravel fine grain materials. Background technique [0002] For the manufacturer of any product, before manufacturing the product, it is necessary to confirm whether the incoming material meets the specification requirements. The same is true for concrete manufacturers. Generally speaking, concrete mainly includes coarse aggregates, fine aggregates, cement and chemical additives (interfacial active agents) and other components, among which fine aggregates contain what people often call fine sand and mud, and the boundary is No. 200 sieve ( Particle size 75µm). Although the sources of fine-grained materials are fixed (such as sand from a certain stream, excavated sand for construction sites, and machine-made sand), each batch of incoming materials may come from different location...

Problems solved by technology

The analysis of chemical substances in mud components is generally not carried out in the ready-mixed concrete plant, and needs to be sent to the laboratory, which is time-consuming and expensive

However, CNS491 or other specifications do not provide a relevant and easy way to solve this problem
