【摘要】 围绕再生EPS颗粒对C40混凝土抗压强度的影响开展了试验研究，采用两种不同直径的再生EPS颗粒（0.3～0.5 mm和0.5～0.8 mm）分别制备三种孔隙率立方体试件（3%、5%、8%）。探究了再生EPS颗粒在不同直径、孔隙率和养护龄期条件下对C40混凝土试件强度的影响。试验结果表明，掺入EPS颗粒的C40混凝土结构随颗粒直径的增加强度损失增加，28d养护的C40混凝土强度损失平均高于7 d养护龄期。更多还原

【Abstract】 A systematic experimental study was carried out on the effect of recycled EPS particles on the strength of C40 concrete, and two different diameters of recycled EPS particles(0.3～0.5 mm and 0.5～0.8 mm) were used to prefabricate three porosity cube specimens(3%, 5% and 8%). The influence of recycled EPS particles on the strength of C40 concrete specimens under different porosity、particle diameter and curing ages conditions was explored. With the increase of particle diameter, the strength loss of C40 concrete structure incorporated with EPS particles increased, and the strength loss of C40 concrete in 28 days curing was higher than that of 7 days curing on average.更多还原
