Unconfined cohesive yield strength of 4 iron ore fines

By way of illustration, the unconfined yield strength of the four different iron ore fines is shown in Figure 5. The highest strength of Ore B is clearly evident at 70% of FDS. ...

DEM study of the mechanical strength of iron ore compacts

Numerical simulations based on the discrete element method (DEM) were conducted to study the die compaction of iron ore fines and the mechanical strength of formed compacts under the uniaxial unconfined compression. To mimic the strength gained after the die compaction and brittle behaviour of compacts under compression, a bonded particle model ...

Effects of iron and chrome slag on the index compaction

Feb 24, 2016 The effect of chrome and iron slag on unconfined compressive strength. Strength and deformation are among the most important problems encountered on clay soils. The strength of soft soils can be determined by many tests such as triaxial compression test, unconfined compressive strength test etc., in the laboratory environment.

Mechanical Properties of Low Plasticity Clay Soil

Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and ...

NM Institute of Technology Chemical Soil Stabilization

Mar 01, 2013 The strength of compacted stabilized soil with bitumen is measured in terms of unconfined compressive strength. Figure 20 shows that initially there is an increase in strength with quantity of binder added until maximum strength is reached and after the peak there is a slow drop in unconfined compressive strength of the soil (Giffen et al., 1978).

Stabilization of Clayey Silt Soil Using Small Amounts of

Effects of using small amounts of a Petrit T, a by-product 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 ...

1 Introduction

The results of the 7 d unconfined compressive strength test of the recycled mixture are shown in Figure 4. Figure 2. 2000 kN press machine. Figure 3. Pavement material strength tester. Figure 4. 7 d compressive strength test results. The test results show that the recycled mixture has good compressive strength.

Effect of Elapsed Time after Mixing on the Strength

The study evaluated the effect of elapsed time after mixing on the strength properties of lime and iron ore tailings (IOT) treated black cotton soil (BCS) (an expansive tropical black clay) as road construction material. BCS was treated with 0, 2, 4, 6, and 8% lime and 0, 2, 4, 6, 8, and 10% IOT content by dry weight of soil. Tests carried out include Atterberg limits, compaction, unconfined ...
