<p>The present invention relates to a cement concrete composition using waste silicon sludge, a method of manufacturing the cement concrete composition, and a concrete pavement repairing method using the same. The cement concrete composition comprises: 3 to 40 wt% of a high-early strength cement binder; 20 to 75 wt% of a fine aggregate, 10 to 65 wt% of a coarse aggregate; 0.01 to 15 wt% of a performance improvement admixture; and 0.1 to 15 wt% of water, wherein the high-early strength cement binder includes: 20 to 90 wt% of ordinary Portland cement; 1 to 50 wt% of silicon waste sludge; 1 to 35 wt% of calcium alumina cement; 1 to 25 wt% of clinoptilolite; 1 to 15 wt% of anhydrous gypsum; 0.01 to 15 wt% of zinc sulfate; 0.01 to 15 wt% of magnesium sulfate; 0.01 to 10 wt% of lithium hydroxide; and 0.01 to 5 wt% of a water-reducing agent. According to the present invention, the cement concrete composition can improve strength and durability performance of concrete, and can be useful for recycling industrial waste by using the waste silicon sludge. Also, the cement concrete composition can be replaced with conventional high-early strength Portland cement, thereby reducing manufacturing costs thereof.</p> |
