statistical evaluation of the cured (sintered) compressive strengths proved that pellets prepared from UG2 ore are likely to have the same, or better, compressive strength than pellets prepared from metallurgical-grade chromite ore. The cured abrasion strength of the UG2 pellets was also superior to that of the metallurgical-grade pellets.
They are quite strong in compressive strength, generally above 150 kg/cm 2 and low in porosity and absorption. Use: Despite their high strength, these types of bricks are unfit for use in building construction. This is because of their distorted shape and irregular size.

compressive strength of concrete when chromium waste is used as admixture. In this respect, experimental factors at two levels, which are admixture type (chromite/ chromite+ superplastizer), admixture percentage (5-15%) and cure duration (7-28 days), are selected as possible candidates affecting the compressive strength.
Compressive strength of particularly heavy (chromite) concrete depends on the type of cement used and may reach 40 MPa. Heat conductivity and coefficient of thermal expansion at 700 o C is 1.57 W/(mK) and 3.4x10-6 o C-1, respectively. The permissible temperature operating limit of particularly heavy (chromite) concrete is 1700 o C .
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.

Sep 13, 2011· It was found that at 28 days, the C1, C2, and C3 concretes had compressive strength of 29.5, 28.0, and 24.3 MPa, respectively, while that of R (reference) concrete was 31.1 MPa. The results showed that the higher the replacement of chromite industry waste (C), the lower the compressive strength of concrete at each curing age.

requirements of a structure. The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load
strength and porosity of the sintered pellets play a significant role in smelting reduction. Granulometry of the chromite fines used for pellet production is an imperative enabler which controls the pellet strength and porosity by packing of particles and formation of bonds due to melting of gangues at high temperature sintering.
• Heat-hardening reduced the shatter strength of the cured briquettes, but it had a positive impact on the compressive strength, as the temperature and holding time were increased. • For all the combinations tried, the shatter strength values of the briquettes on a comparative scale were as follows: 1.
