摘要: 在胶凝堆石料单轴抗压试验基础上, 分析了胶凝堆石料抗压强度和弹性模量随龄期的发展规律, 并通过试验数据回归分析, 得出胶凝堆石料强度和弹性模量与龄期之间的相关关系。研究结果表明①胶凝堆石料抗压强度随龄期的增长而增长;②胶凝堆石料弹性模量低于一般混凝土, 且随龄期的增加而不断提高, 但在早期(14 d内)增长较快, 之后以接近斜线方式缓慢增长。该成果可为胶凝堆石料的工程(胶凝堆石坝)应用及技术设计提供参考依据。

Abstract: The variations of cemented sand and gravel(CSG) material’s compressive strength and elastic modulus against age were researched through uniaxial compression tests. The relations respectively between age and compressive strength, age and elastic modulus were obtained by regression analysis on the test data. Results showed that the compressive strength and elastic modulus of CSG material increased along with age the elastic modulus was smaller than that of ordinary concrete, and increased rapidly in the early stage(in first 14 days) before the growth slowed down. This research could be a reference for the engineering application and technical design of CSG material.

Key words: CSG material, compression tests, strength, elastic modulus
