    Abstract

    High-efficient recycling of solid waste from the semiconductor or textile dyeing industry has been a challenge since these industrial waste not only brings a heavy burden to enterprises but also seriously affects our ecological environment. Here, a feasible method is proposed to recycle this solid waste by transferring it into high value-added ceramsites. They were prepared by using the third grade sand of cutting silicon (TGSCS) and textile dyeing sludge (TDS) as raw materials and composed mainly of SiO2-Al2O3. Through systematic analysis of the experimental results, it was concluded that the optimized ratios of the TGSCS and the TDS should range from 1:1.5 to 1:3, while the sintering temperature should be around 1150°C. These lightweight ceramsites can have excellent properties of the cylinder compressive strength of 4.65 MPa and bulk density of 477 kg/m3. The potential expansion mechanism was thought to be related to both TGSCS and TDS as they reacted with Fe2O3 impurity to form CO2/CO gases. This work is to prepare lightweight ceramsites and to recycle solid waste.
