Analysis of Unconfined Compressive Strength Calculation Formula of Soil-Cement

Abstract

The soil-cement is applied in hydraulic engineering, construction engineering and highway engineering. It needs take much time and energy to do the experiment of soil-cement design, because the influence factors of soil-cement unconfined compressive strength are many. The study is based on the former experimentations, and quantitative analyzed relationships among soil-cement unconfined compressive strength, earthiness, cement mixing amount and curing time by nonlinear curve fitting. Then, rational experience formula is given in this paper. It is tested in Nantong Building foundation excavation project, and the result proves that formula is practical.

Evaluation of flexural-tensile strength of high-performance soil-cement (HPSC) specimen bodies

“…Soil-cement is a widely used construction material consisting of a mixture of soil and cement (Wang & Ma, 2011). This technique can be used for various applications, the most common ones being: improvement of soil conditions for foundations and/or tunnels execution, road paving and production of artifacts such as bricks, blocks and/or plates (Ferreira & Freire, 2004;Wang et al, 2014;Durante et al, 2015;Yi et al, 2018;Thoma et al, 2020;Martins et al, 2022).…”
