Properties of Clay Mixed with Sticky Rice Juice and Tung Oil

Stabilization of an earthen material with Tung oil: compaction, strength and hydrophobic enhancement

“…Tung oil is able to harden after mixing with soils within 7 days due to oxidative polymerization (Lin and Lourenço, 2020;Tang et al, 2010;Tang et al, 2006). To investigate this hardening effect on the compaction behaviour, MCT tests were conducted immediately after mixing with Tung oil (hereinafter fresh stabilized soils) and after 7-day equilibrium (hardened stabilized soils).…”

“…For the fresh stabilized soils, a given concentration of Tung oil (0, 1, 5, 8, 10 and 15%) was firstly mixed with 1.0 kg of CDG. This concentration range was based on preliminary tests and other works (e.g., Lin et al, 2019;Tang et al, 2006) where 5~10% of Tung oil can induce extreme soil hydrophobicity. After that, water was immediately added to the mixed soils (10~28%) and compaction was conducted.…”

“…Zhang et al (2016) considered the use of Tung oil to enhance the water resistance of earthen monuments. Tang et al (2010) mixed the soils with Tung oil and sticky rice juice to ameliorate its durability under wetting-drying cycles, and explored its use to reduce water infiltration in a clayey soil (Tang et al, 2006). Lin et al (2019) investigated the effects of Tung oil (heated and unheated) on soil hydrophobicity and the strength of soil aggregates, showing that by using high temperature, soil can be more hydrophobic and consequently the consumption of Tung oil can be saved.…”

Impact of Municipal Solid Waste Disposal on Compaction Characteristics and Strength of Red Soil

“…The unconfined compressive strength tests [8] were conducted on soil samples obtained at defined depths as mentioned in Tables 3 and 4. The results are compared…”
