Abstract: Concrete curing is influenced by water absorption and desorption of shale ceramsite. In order to determine the influence law of shale ceramsite concrete workability and strength, and failure law affected by different sand rate and water-cement ratio, the slump, compressive strength and flexural strength of shale ceramsite concrete are compared and analyzed. The results show that the slump of shale ceramsite concrete decreases with the increase of sand rate. Determined to meet the best road performance of the sand rate range (not added water reducing agent) is 35%～39%. Shale ceramsite concrete strength increases with the increase of age growth, the same change rule as the normal concrete. However, at the beginning, with the increase of water cement ratio, concrete strength presents increased and then decreased. Determined to meet the best road performance of the water-cement ratio range is 0.37～0.39. The fracture of shale ceramsite concrete is usually ceramsite damage and cement mortar fracture, therefore, the strength of concrete is developed completely through the coordination of those two factors.
