摘要
根据植物生长所需条件对植生型多孔混凝土的配合比进行了研究,并对其物理力学性能进行考察。结果表明:多孔混凝土的抗压强度随水胶比增大、灰骨比增大以及骨料粒径的减小而增加;适合的植生型多孔混凝土配合比为:水胶比0.36,灰骨比0.17,骨料级配为5~10mm的占总量的20%,15~20mm的占总量的80%。
According to the need for plant growing ,Research on mix ratio and mechanical properties of porous concrete for plant-growing are carried. The results shows: compressive strength increase with water/binder, fly ash/aggregate increase, also with decrease of size of aggregate. The proper mix ratio is: water/binder 0.36, fly ash/aggregate 0.17, the size of aggregate ( 5-10mm 20%, 15-20mm 80% ).
