摘　　要：测定了不同养护龄期(3d、7d、28d)下普通混凝土与粉煤灰陶粒混凝土的基本力学性能(抗压、抗折强度),比较二者抗压与抗折强度之间的关系以及早龄期强度增长规律。结果表明,适当配合比下的粉煤灰陶粒混凝土满足路面强度结构设计要求;随着养护龄期的增长混凝土强度均不断提高。The basic mechanical properties（compressive strength, flexural strength） of ordinary concrete and fly ash aggregate concrete in different curing periods （3d, 7d, 28d） hanve been measured.Compared with the relationship between compressive strengthand flexural strength and the strength growth laws of early age,the results show thatfly ash aggregate concrete under the condition of appropriate mix proportion can meet the design requirement,and with the increase of curing agethe strength of both concrete increases.

关 键 词：粉煤灰陶粒混凝土 早龄期 抗压强度 抗折强度 配合比
