In this paper, a shell structure ceramsite has been prepared and researched in order to attempt a new method of producing lightweight ceramsite. In the experiment, raw material was made into slurry and polypropylene balls were treated with the soak-and-pick process in the slurry to make the green body; later, the green body was dried and fired in the furnace to make the shell structure ceramsite. The result showed that the shell structure ceramsite has an appropriate cylindrical compressive strength (0.87 MPa) with a bulk density at a low level (0.375 × 103 kg/m), which can be used for lightweight concrete preparation, and with its special structure, it can be used for many other purposes.
本文制备并研究了一种壳结构陶粒，旨在尝试一种生产轻质陶粒的新方法。实验中，将原料制成浆料，把聚丙烯球在浆料中采用浸泡-捞出工艺进行处理以制成坯体；随后，将坯体干燥并在炉中烧制以制成壳结构陶粒。结果表明，壳结构陶粒具有适宜的圆柱抗压强度（0.87MPa），堆积密度处于较低水平（0.375×10³kg/m），可用于制备轻质混凝土，并且因其特殊结构，还可用于许多其他用途。
