2.2 Economic Benefit
The ceramsite concrete -hollow blocks and partition board is one of excellent properties
new wall materials, which use ceramsite instead of gravel. According to calculate,
ceramsite concrete used in high-rise buildings, can reduce weight 30%, reduce labor
intensity 20%, reduce cost 10%.
2.3 Environmental Benefits
The sludge ceramsite, will greatly reduce the severe sludge treatment problems, In the
process of calcining Large numbers of bacteria be killed and heavy metal is fixed in
ceramsite which Avoid heavy metals from agricultural products to enter the food chain,
and finally to enter the body. Especially fits our reduction, harmless and recycling solid
waste treatment.
3 Conclusion
Ceramsite as a kind of lightweight aggregate can replace common sand to placing
lightweight aggregate concrete, ceramsite as a kind of lightweight aggregate, with its
light, heat preservation, environmental protection and other characteristics has the good
application value. So using sludge produced ceramsite, not only can solve of
wastewater treatment of sludge outlet problem, but also can obtain certain economic
returns.
