"沙琪玛骨架"绿化混凝土的研制试验

以水泥、建筑废料、大粒径碎石、营养土、有机肥等为原料,研制出一种能适合植物生长、排列较松、耐冲刷又具有一定强度的空间骨架绿化混凝土,将其形象地称为”沙琪玛骨架”绿化混凝土．主要对其组成机理、结构特点、营养土灌浆、抗压力学性能和草种建植等方面进行了研制与试验,从抗压应力一应变曲线的多峰值跳跃现象说明了粗骨料之间接触点的粘结强度是决定“沙琪玛骨架”绿化混凝土强度的关键;通过植草试验说明“沙琪玛骨架”对提高植物的耐践踏性等方面的优点,讨论了绿化混凝土的生态、经济和社会应用价值．

Experiments and Manufacturing of "Shaqima" Planting Concrete

A new kind of planting concrete is studied,which is made of cement,building wastes,stones,nourishment soil,organic-fertilizer,etc.With a loose structure and sufficient strength therefore named "Shaqima" planting concrete, it suits plant growth and can withstand washing-out.The following topics are studied: composing mechanism,structural features,filling of nourishment soil,compression-resistance capability,choice of grass seeds,etc.Multiple peaks in the stress-strain curve show that the contact tension at bonding points between thick material contacts is the main factor that determines the strength of the planting concrete.Trampling resistance capability of plants and some other merits have been demonstrated by tests.The ecological and economic values and applications are discussed.
