Research on Strength and Microstructure Feature of Solidified Saline Soil in Inshore with Slag Cementitious Material
Saline soil in inshore is a kind of special soil with poor engineering properties such as salt expansion and subsidence. The main purpose of this subject is to find a new material to solidify saline soil, so as to solve the fundamental problems that exist in the solidified saline soil at present. Through the chemical analysis, the unconfined compressive strength, SEM analysis experiment, this paper studied the strength and microstructure of solidified soil with the slag cementitious material. The test results showed that the 7th day’s strength of the test blocks which were cured in the standard case reached to 8.34MPa, the water-related stability was 1.62 times than the soil-cement when the mixing mass is 10%. The soil generated a large number of needle-bar-like crystals in the SEM graph. The research has shown that mixing slag cementitious material into the saline soil can reduce the soluble salt content of saline soil, increase water-related stability and improve the strength of the soil.
