Experiments were carried out to determine the microstrength of different high ash coke samples obtained from 2 and 250 kg ovens. Microstrength of coke is determined using small quantity of sample (50 m<I>l</I>) with small sample size (3–6 mm) and is an indicator of the inherent strength of the coke matter. The microstrength values obtained were then correlated with the ash, VM/reflectance and fluidity of the parent coal and also conventional strength indices of coke like M10 and CSR. The correlations obtained indicate that except in the case of very strong coke, correlation exists between microstrength, M10 and CSR values of coke.
