Lightweight foamed concrete wall of lightweight foamed concrete using waste expanded polystyrene aggregate composition and take advantage of this manufacturing method

摘要

The present invention relates to an ultralight foamed concrete wall composition including 90-98 wt% of a high early strength-type blended cement slurry, 1-8 wt% of waste foamed polystyrene having a density in a range of 0.002-0.010, a circular diameter, and a particle size of 2-15 mm, and 1-8 wt% of a foamed group obtained by diluting an animal or vegetable foaming agent in water at the ratio of 1:25-50 wt% and foaming using compressed air, and a manufacturing method of ultralight foamed concrete wall using the same. The high early strength-type blended cement slurry is obtained by mixing 50-80 wt% of a high early strength-type blended cement obtained by pulverizing 70-94 kg of a cement, 3-15 kg of calcium sulfoaluminate, 2-10 kg of anhydrous plaster and 1-5 kg of a slaked lime to a pulverized degree of 4,000-6,000 cm2/g, 20-50 wt% of water, and 0.1-0.5 wt% of a water reducing agent.
