Abstract : To achieve comprehensive utilization of construction waste recycled aggregates, the research focused on construction waste recycled aggregates and prefabricated slabs.  Experimental studies were conducted on the apparent density, clay lump content, crushing index, mass loss rate, and particle gradation of the recycled aggregates, as well as on the compressive strength, shear strength, impact resistance, and drying shrinkage of the prefabricated slabs. .  The results show that : The apparent density of recycled aggregate is about 12% lower than that of natural aggregate .  The ompressive strength ratio of recycled aggregate slab, autoclaved aerated block masonry and precast light concrete is about 1 ∶ 0. 55 ∶ 0. 64; The ratio of dry shrinkage of recycled aggregate slab, autoclaved aerated block masonry and precast light concrete is about 1 ∶ 0. 92 ∶ 1. 18. Using construction waste as aggregate can reduce carbon emissions and lower construction costs, and can be used for the construction of self built houses in rural areas.

Key words: construction waste; recycled aggregate; prefabricated slats; apparent density; compressive strength; dry shrinkage
