Technical field
Recycled aggregate process field in the utility model concrete works, in particular to it is a kind of solidifying using hydrated calcium silicate
The device of sol solution modification regeneration aggregate.
Background technique
With the rapid development of urbanization process, currently, all there is the case where garbage-surrounded city in the big city of China various regions.
Traditional garbage loading embeading mode land occupation, while will cause the massive pollution in soil and underground water, air.Therefore, it is necessary to
Resource utilization is carried out to municipal refuse.According to statistics, currently, China's building waste has accounted for 40% of municipal refuse or so, and
Discarded concrete rubbish accounts for 50% or so of building waste again, therefore, prepares recycled aggregate for mixing using discarded concrete
Concrete processed is the important channel realizing Changing Urban Garbage into Resources and utilizing.
Currently, being mainly used in the non-bearings such as road cushion using the concrete that recycled aggregate is prepared, it is desirable that low engineering
Occasion.It is main reason is that recycled aggregate is big compared to natural aggregate water absorption, powder containing quantity is high, aggregate voidage is big, it is difficult to
Make the concrete of intensity height, Workable.Why water absorption is big, aggregate voidage is big, powder containing quantity is high for recycled aggregate, with
