One such formation mechanism is transient confinement, wherein the groundwater level rises after heavy rainfall.
Such improvement of additive-modified OPC solidified sandy silt is due to the formation of the crystalline compound or the gradation composition improvement via field emission scanning electron and X-ray diffraction analysis.Ĭonfined water is a common type of groundwater in accumulation slopes and has several formation mechanisms. The optimal contents of additive gypsum, clay particles, and fly ash are determined to be 2%, 4%, and 4%, respectively. There are four types of additives (gypsum, lime, clay particles, and fly ash) at mass fractions of 2, 3, and 4% that are considered in order to study their mechanical properties (unconfined compression, indirect tensile, flexural strength, and compressive resilient modulus) at 7, 14, 28, 60, and 90 days.
In this study, the effect of additive type and mass fraction on the microstructure and mechanical properties of solidified sandy silt are investigated. Alternative products are used in cementitious materials to enhance the strength and to reduce OPC consumption. The ordinary Portland cement (OPC)-based solidification process is used extensively to reinforce soils due to its available and good bonding properties.
