The purpose of the study reduced environmental load and CO2 gas, when the cement was produced, using cement substitutes. It was consisted of blast furnace slag, red mud and silica fume which were industrial byproduct. PVA fiber was set to 5 levels of 0, 0.5, 1, 1.5, 2(%) ect in the low carbon inorganic Composites drawn in the advanced research. The ring floor, setting time, compressive strength, and flexural strength were set to the measure and the experiment was carried out. The experiment was carried out, The liquidity was more and more reduced as the percentage of Reinforced of PVA fiber increased. However this difference indicated the tendency that it represents the slight tendency and the final setting time is reduced in the flocculation test. In the strength test, the compressive strength was lower than Plain with the age on 1st in case of Reinforced PVA fiber. The age showed the compressive strength more than 50MPa From 3 day of agerd. And the flexural strength showed excellently as PVA percentage of dilution increased.
