摘要
Abstract
It utilizes recycled fine aggregate as an equal mass replacement for natural sand,with the replace-ment ratio of recycled sand,water-cement ratio,and thickener dosage as influencing factors,to investigate their effects on the fluidity and compressive strength of 3D printed recycled fine aggregate concrete,aiming to design an optimal mix proportion.The results demonstrate that both the fluidity and compressive strength of concrete decrease with increasing recycled sand replacement ratio.An increase in water-cement ratio enhances concrete fluidity but reduces compressive strength.Higher thickener dosage leads to reduced bleeding,accompanied by decreases in both fluidity and compressive strength of the concrete.关键词
