This experiment uses a jaw crusher to crush waste concrete into recycled aggregates, and then uses a sieve to separate fine particles (particle size<5mm) from coarse particles (particle size 5mm).
Due to factors such as high water absorption, suitable recycling and reuse methods have not yet been found for fine particles.
Therefore, this article only conducts relevant research on recycled coarse aggregates.
The natural coarse aggregate for comparison is crushed stone produced by a quarry in Nanning, and the sand is Yongjiang River sand (with a fineness modulus of 2.
8).
