Abstract: For improving the granular shape and the water absorption of the ceramicite, a kind of expanded shale with large particle size and poor shape has been crushed and a lightweight aggregate with better grading, which include coarse aggregate and fine aggregate, has been obtained. Then, a hydrophobic treatment on the surface of these aggregates has been done for improving the water absorption. Afterward, the concrete with this managed aggregates is prepared and tested. The results show that a lightweight aggregate with continual grading and a nominal size of 5～16mm can be made by crushing of ceramisite, and after hydrophobic treatment for them, the 1h water absorption can be decreased from 13.5% to 3.2%, and the water requirement and slump loss of concrete made with crushed and treated ceramicite are equilibrated to the concrete made with original ceremicite or crushed and wetted ceramicite, but the bleeding rate will be decreased and the strength will be enhanced for more. Besides, a ceramic sand with the nominal size of 0～5mm and the proper grading can also be gotton by crushing the ceramicite, and after the surface treatment, its 1h water absorption will be decreased from 22.0% to 20.5%, the decreasing degree is not so obvious.
