表面处理轻集料混凝土的性能
PROPERTIES OF CONCRETE WITH SURFACE-TREATED LIGHTWEIGHT AGGREGATE
摘要
Abstract
Lightweight aggregate concrete is being more widely used in construction. The surface texture, shape, and water absorption of lightweight aggregate have an effect on the water demand and rheological properties of lightweight aggregate concrete. The results indicate that surface treatment of expanded shale lightweight aggregate with a hydrophobic surface, decreases the water adsorption of the aggregate at early and later ages. The concrete with the surface-treated lightweight aggregate requires less water than that containing dry or pre-saturated untreated expanded shale for a given slump. Also, the former shows less slump loss and higher compressive strength than the latter.关键词
