Low level laser (LLL) was applied to induct destruction of the low cement high alumina refractory concrete (LCC) samples. Three different series of samples were used in the experiment: a reference one dried at 105 degrees C, sintered at 1300 degrees C and sintered at 1600 degrees C. Level of destruction during time interval from 5 to 25 min was monitored by measuring surface and depth of damage. Obtained results shown that minimal level of destruction was observed for the samples sinteted at 1600 degrees C for the whole time interval.
