Abstract

The invention discloses a detection method of water glass content in water glass improved soil. The detection method comprises the steps of respectively titrating standard samples with different water glass contents, and acquiring hydrochloric acid standard solution consumption of each standard sample at different ages; fitting the hydrochloric acid standard solution consumption of each standard sample at each age to generate a standard curve; acquiring the time of doping water glass in an improved soil detection sample, and calculating an interval between the time of doping the water glass in the sample and water glass content detection time; titrating the detection sample, and acquiring hydrochloric acid standard solution actual consumption; comparing with the standard curve according to the time interval and the hydrochloric acid standard solution actual consumption of the detection sample, determining the hydrochloric acid standard solution actual consumption of the detection sample to be between two curve ranges of the standard curve, and calculating to acquire the water glass content of the detection sample. According to the detection method of the water glass content in the water glass improved soil provided by the invention, the water glass content in the water glass improved soil can be effectively detected at different ages, and the actual situation is simulated to the maximum extent, so that the detection method provided by the invention is accurate and effective.

Description

Technical field

[0001] The invention relates to a method for detecting the content of water glass in water glass improved soil, and belongs to the technical field of chemistry and geotechnical analysis. Background technique

[0002] The current evaluation methods of dual-liquid grouting effect, such as the use of rock and soil core samples for strength testing, in-situ testing, and load testing, or the use of geophysical methods and means to detect changes in the physical properties of the rock and soil layers before and after grouting. Other indirect evaluations after grouting cannot be used to detect whether the grouting amount meets the requirements in real time during the grouting process; in addition, water glass modified soil has gradually begun to be used as a filler in engineering.

[0003] Although water glass has been widely used in dual-liquid grouting and soil improvement, there is no systematic method for detecting the content of water glass in dual-liquid grouting or ...
