Previous studies have demonstrated that lightweight aggregate cracks as the temperature of the sintering process rises, such that an appropriate preheating temperature and time are prerequisites for ensuring the successful preparation of lightweight aggregate [32]. Fig. 6 shows the LDS lightweight aggregate obtained using different preheating temperatures and times. Fig. 6a shows that for preheating temperatures below 400℃ and preheating times below 30 min, the LDS lightweight aggregate can

The recycling of lake-dredged sediments (LDS) is an environmental issue of great concern, and its reuse in ecological slope protection is a new endeavor with economic and environmental advantages. However, the feasible process and reasonable parameters of this recycling concept are still unrevealed. In this paper, we presented a guiding framework for recycling lake-dredged sediments into lightweight aggregate for eco-friendly porous vegetation concrete blocks. The laboratory tests show that the LDS from Dongting Lake could be directly sintered ...
