The study which it describes the high concrete which industrial by-product used garnet powder was quality of residual strength after heating. The test unit water content l60kg/m', water reunion ratio did with 30%, 35% and the aggregate ratio is 40%, 42%, 44%, displacement ratio admixture is 0%, 10%, 20%. Admixture garnet powder, fly ash, blast-furnace slag and it was compared with the residual strength of concrete after was heated to normal temperature, 50℃,100℃, l50℃, 200℃, 350℃, 500℃, 600℃, 800℃.With this test was got the next conclusion. To previously 350℃, the weight reduction was not big, it was visible the weight reduction which was sudden from 350℃, and it showed the aspect which also the compressive strength reduction is identical. It compared with admixture nothing replacement concrete, garnet replacement concrete relatively weight reduction and compressive reduction appeared small. Like this tendency recording where the replacement ratio will be increased the tendency which appeared relative small.
