Abstract Taking cement mortar composite soil in Hetao irrigation district as research object，relationship between amount of mixed sand and the strength is studied，aiming to find the suitable sand amount mixed in the cement mortar composite soil which has good engineering adaptability. Meanwhile，unconfined compressive strength，deformation characteristics and the microcosmic structure of cement mortar composite soil with different amounts of mixed sand and ages are analyzed. The laws of strength and deformation characteristics of cement mortar composite soil are influenced by amount of mixed sand and age of sand are obtained. The results show that，if a certain amount of sand is mixed in the cement mortar composite soil，strength of cement soil improves effectively，as well as structure of cement-soil. There is an optimal amount of mixed sand in the certain cement content which makes cement mortar composite soil having the highest strength and the stress-strain curves all showing peak values.

Key words： soil mechanics cement mortar composite soil early structure amount of mixed sand unconfined compressive strength microstructure
