Study on the Microstructural Features of the Soil Formed by the mixture of soft rock and sand

Abstract

Abstract The scanning electron microscope was used to observe the microstructure of vermiculite soft rock, sand, and compound soil. Based on the observation results, the interaction relationship between vermiculite and sand particles was found during the formation of the compounded soil. The microscopic process reveals the sand-fixing mechanism of the composite soil, and quantitatively measures the sand-fixing effect of the composite soil. To provide a scientific reference at the micro-scale for improving the theory and technology of rapid mixing of soft rock and sand in the Mu Us Sandy Land.
