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
