Elastic properties of fly ash-stabilized mixes
Stabilized mixes are used in the construction of bearing layers in asphalt and concrete pavement structures. Two nondestructive methods: resonant frequency method and ultrasonic pulse velocity method, were used for estimation of elastic properties of fly ash-stabilized mixes. Stabilized mixes were designed containing sand from the river Drava and binder composed of different share of cement and...
متن کاملGeotechnical Characterization Cement - Fly Ash –fibers Mix
The fly ash is a waste produced mostly from the burning of coal in thermal power station which contributes to environmental pollution. It is naturally-cementitious coal combustion by-product. Many studies have been reported in the literature on the performance evaluation of soil – fly ash system as well soil-fly ashfiber system. Although ample studies have been reported with randomly distribute...
متن کاملThe Effect of Rice Husk Ash on Mechanical Properties of Clayey Soils Stabilized with Lime in the Presence of Sulphate
Geotechnical engineers, in many cases face with low strength or high swelling potential of clayey soils. Stabilization methods are used to improve the mechanical properties of this type of soils. Lime and cement are the most popular materials used in chemical stabilization of clayey soils. If sulphate exists in the stabilized clayey soil with lime, or if soil is exposed to sulphates, problems s...
متن کاملTest Study on Strength and Permeability Properties of Lime-Fly Ash Loess under Freeze-Thaw Cycles
In order to study the application of lime-fly ash loess in permafrost subgrade engineering, uniaxial compressive test, fast direct shearing test and permeability tests were carried out on lime-fly ash loess under different curing ages and freeze-thaw cycles. Uniaxial compressive strength of lime-fly ash loess increases slowly with the curing ages, and can reach 3.5 Mpa after the curing ages of ...
متن کاملEffect of heat treatment on properties of steam cured fly ash – lime compacts
Four different varieties of class F fly ashes, collected from different sources from the state of West Bengal (India) were mixed with lime in 9 : 1 wt ratio, followed by compaction of the mixes. The compacts were subjected to steam curing to develop an optimum strength by the reaction between fly ash and lime. The steam cured compacts were heated at different elevated temperatures and free lime...
