<p>PURPOSE: An environment-friendly cement based double floor material composition is provided to reduce the environment contamination, the crack resistance of a cement based double floor material, water resistance, and curving resistance by using waste sludge produced from a terrazzo production process. CONSTITUTION: An environment-friendly cement based double floor material composition contains 30-60 wt% of cement, 30-60wt% of fine aggregate, and 10-25 wt% of terrazzo sludge. 20-40 wt% of water is contained for the weight of the cement, and 1.0-2.0 wt% of dispersing agent is contained for the weight of the cement. The fineness modulus of the fine aggregate is 2.5-2.9. The gibbsite contents in the terrazzo sludge is 85 wt% when the gibbsite is transferred to aluminum oxide. A production method of the environment-friendly cement based double floor material composition comprises the following steps: producing slurry by mixing the cement, water, and the dispersing agent; adding the terrazzo sludge to the mixture; and adding the fine aggregate to the mixture.</p> |
