2018-8-1  Soil-cement mixture is a product of cement grouting or mixing with soils. Chemicals, such as sodium silicate, are frequently used in combination to meet specific needs. Admixing of sodium silicate can enhance the UCS of improved soils with less dosage used, but the most important characteristic is its penetrability to very fine fissures or soil ...

In Situ Soil-Cement Mixtures: definitions, properties, and ...

2018-10-2  Soil-cement mixtures are simply mixtures of soil and cementitious reagents. These mixtures often have a similar overall structure to concrete in that both are aggregate materials mixed with Portland cement, alone or in combination with inert or other cementitious reagents. However, soil-cement mixtures are unlike concrete in two key ways 1) the mixtures contain a much smaller amount of cementitious reagent(s) and 2) the “aggregate” proportion is made up of a variety of different soil types with varying particle sizes, ranging from plastic clays to clean gravels. Concrete aggregate is made up of clean, strong particles of sand and gravel. Standard mix ratios for soil-cement
