摘要
本文以内蒙古东部区天然浮石为粗骨料,对不同减水剂的轻骨料混凝土进行3d、7d、14d、28d抗压强度、棱柱体强度及弹性模量和峰值应变试验测定,总结了轻骨料混凝土早期强度、弹性模量的关系,以及不同掺量的减水剂对轻骨料混凝土早期强度的影响。
The texts are carried out to LWAC mixed with different ratio of water reducer,in which natural pumice from the eastern Inner Mongolia are used as coarse aggregate. The contents of texts include： compressive strength,strength of a prism, modulus of elasticity and strain corresponding to the maximum stress in 3 d ,7 d, 14 d ,28 d. The relationship between early strength and modulus of elasticity of LWAC is obtained after the texts. The different to original strength of LWAC by the adding of water reducer is analyzed in the end.
