Strength development in silty clay stabilized with calcium ... · Calcium carbide residue (CCR) and fly ash (FA) are waste products from acetylene gas factories and power plants, respectively. The mixture of CCR and FA can produce a cementitious material because CCR contains a large amount of Ca(OH) 2 while FA is a pozzolanic material. Soil stabilization by CCR is classified using three zones: active, inert and deterioration.
Reuse of Excavated Clayey Silt in Cement–Fly Ash–Bentonite ...Excavated soils from tunnel construction need high treatment cost and pollute the environment. To investigate the feasibility of excavated clayey silt reused in backfill grout, the flowability, stability and strength were taken as measurement indexes of grouting performance. The clayey silt was tested to be reused as substitutes for fly ash, bentonite and sand, respectively.
Stabilization of Clayey Silt Soil Using Small Amounts of ...Effects of using small amounts of a Petrit T, a byproduct of manufacture sponge iron, to modify clayey silt soil were investigated in this study. Petrit T was added at 2%, 4% and 7% of soil dry weight. A series of unconfined compressive strength tests, consistency limits tests and pH tests were conducted at 7, 14, 28, 60 and 90 days of curing periods to evaluate the physical and mechanical ...
