Reuse of waste ferrochrome slag in the production of

The flowability test was performed to evaluate the mortar's behavior in a fresh state. Tests for the compressive strength, flexural strength, drying shrinkage, thermal conductivity, and specific heat of the blended mortars have been conducted according to ASTM standards at 3, 7, and 28 days of curing.

Sustainable solidification of ferrochrome slag through

Aug 01, 2019 Ferrochrome (FeCr) slag was used as a precursor for the synthesis of a geopolymer. The effect of KOH concentration, liquid solid ratio (L/S), content of potassium metalisicate (KS) or potassium aluminate (KA), curing time on the unconfined compressive strength (UCS) and metal leachability of the synthesised geopolymer was investigated. A 10 M KOH and an L/S of 0.26 yielded …

Rock Strength (Shear strength, compressive strength

Strength is the capacity to sustain (support): Shear stress (shear strength) Compressive normal stress (crushing strength) Tensile stress (tensile strength) Bending stress (bending or beam strength) All of these depend on effective stresses ( σ′), thus, we must know the pore pressure (p or p o) Rock specimen strength is different than rock

Uniaxial Compressive Strength an overview

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...
