Abstract

A cement-free eco-friendly porous media binder was developed as a cement replacement material (CRM) to be applied in the deep mixing method (DMM) for CMD–SOIL. We measured compression strengths for various mixtures and found that the compression strength of CMD–SOIL was 1.00–1.08 times higher than that of blast furnace slag cement (BFSC) and 1.410–1.945 times higher than the reference strength (2.0 MPa), depending on the moisture content, dosage, and water/binder ratio (W/B). The strength increment ratio (1.730) was slightly lower than that of BFSC (1.780), thereby proving its merit over BFSC as a binder for the DMM.

摘要

开发了一种不含水泥的环保多孔介质粘合剂，作为水泥替代材料 (CRM)，应用于 CMD-SOIL 的深度混合方法 (DMM)。我们测量了各种混合物的抗压强度，发现 CMD-SOIL 的抗压强度比高炉矿渣水泥 (BFSC) 高 1.00-1.08 倍，比参考强度 (2.0 MPa) 高 1.410-1.945 倍，具体取决于水分含量、用量和水/粘合剂比（W / B）。强度增量比 (1.730) 略低于 BFSC (1.780)，因此证明了其优于 BFSC 作为 DMM 粘合剂的优点。
