Preparation of a Novel Structure-Designed Porous Ceramsite for Water Retention.

Ceramsites can be used as water storage materials, but the challenges of low water absorption and short water-retention time are restricted to their application. In this paper, a novel multilayer powder coatings method was used to prepare a structure-designed ceramsite. The results showed that the structure-designed ceramsite can be prepared by a multilayer powder coating method.

Influence of Paste Strength on the Strength of Expanded Polystyrene (EPS) Concrete with Different Densities.

Concrete in which EPS (expanded polystyrene) particles partially or completely replace concrete aggregates is called EPS concrete. Compared to traditional concrete, EPS concrete has a controllable low density and good thermal-insulation performance, which make it promising for prospective applications. At present, research on EPS concrete mostly focuses on increasing its strength and EPS surface modifications.

Study on the Properties and Process Parameters of Different Clays in Disc Granulation.

Sintering solidification is an effective way to treat soil contaminated with nonvolatile heavy metal. The ceramsite prepared from contaminated soil after sintering can be used as lightweight aggregate in concrete. The preparation process of ceramsite can be divided into two steps: granulation and sintering.

The Preparation and Properties of a Shell Structure Ceramsite.

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.
