Consolidation Properties of Compacted Soft Soil Stabilized with Lime
time. When lime is combined with a clay soil, the pH of the pore water increases. When the pH reaches 12.4, the silica and alumina from the clay become soluble and are released from the clay mineral. In turn, the released silica and alumina react with the calcium from the lime to form cement, which strengthens in a gradual process that

Effect of Sand and Sand-Lime Piles on the Behavior of Expansive Clay Soil
The only difference is that the expansive clay soil bed was reinforced with a sand-lime pile (SLP) with a diameter of 38.0 mm instead of a sand pile only. Various percentages of lime 3%, 6%, 9%, 12%, 15%, and 20% by dry weight were mixed carefully with the required dry sand for forming sand-lime piles. 5.

Lime (material) - Wikipedia
Feebly hydraulic lime contains 5-10% clay, slakes in minutes, and sets in about three weeks. It is used for less expensive work and in mild climates. Moderately hydraulic lime contains 11-20% clay, slakes in one to two hours, and sets in approximately one week. It is used for better quality work and exterior walls in freezing climates.

The effects of lime content and environmental ... - ScienceDirect
Lime contents of 5, 7, 9, 11 and 13% by dry weight of expansive clay powder were added to prepare lime-clay specimens. The specimens were prepared at the same dry unit weight of 12.16 kN/m 3 and moisture content of 40% except for tests aimed at the determination of dry unit weight as a function of mellowing period.

Variations in strength of lime-treated soft clays
2. Behaviour of lime-treated soft clays. The introduction of lime to a moist clayey soil induces both physical and chemical changes, resulting in beneficial alterations to its engineering behaviour. Mainly there are four mechanisms of lime–clay–water interaction that are considered to contribute to the modification of material properties.

Utilization of powdered glass in lime-stabilized clayey soil with
Interaction of lime and clay. Astm C 977 specifies on the properties of lime, intended to be used as additives in soil stabilization. It is considered appropriate that the total amount of Calcium Oxide and Magnesium Oxide in the chemical composition of lime to be used in stabilization should be 90% (Astm-C977 2018).

Stabilization of expansive soils using chemical additives: A review
Lime stabilization is not recommended for all types of soils. Addition of lime is beneficial when soil has a plasticity index (PI) more than 10% and at least 25% of its particles passing through 74 μm sieve (National Lime Association, 2004). Further, a soil that has at least 20% clay is preferably suitable for lime stabilization (Broms, 1991).

Lime consumption of different clayey soils - ScienceDirect
Lime reactions with the clay mineral lead to the formation of new Ca-hydrates (CSH, CAH, CSAH). These reactions involve the slow consumption of lime at 20 °C and fast (accelerated) lime consumption at 50 °C with curing time.For all the tested soils, lime needed more than 3 months to be consumed when the curing temperature was 20

Permeability of lime- and cement-treated clayey soils
The permeability (k) of lime- and cement-treated clayey soils was investigated in the laboratory by flexible-wall permeability tests and oedometer tests. Test results indicate that for the cement-treated soils (with up to 8% cement content by dry weight), the value of k is almost equal to that of untreated soils under identical void ratio
