Objective:this paper would research the effects of different dosages of admixtures doped to the adobe wall materials' compressive strength, 30min soaking compressive strength loss rate, water resistance, water absorption rate and resistance drying and watering cycle can be modified by cement, stone powder and fly ash three admixtures which are single-doped into the samples. Result: The single-doped cement can enhance the durability of the adobe wall materials obviously. When the dosage of stone powder's single-doped is 0~5%, it can lower the 30min soaking compressive strength loss rate and water absorption rate. When the dosage of it's single-doped is 5~15%, it raises the 30min soaking compressive strength loss rate and water absorption rate. While the dosage of single-doped fly ash is increasing, it could lower the adobe wall materials' compressive strength, but other performance lowers after that first enhances, and the single-doped dosage of 5% is the turning point performance. Conclusion: Three kind of admixtures can modify the adobe wall materials' durability. When the dosage of stone powder and fly ash's single-doped are 5%, the sample's performance of water resistance is best. It meets the demands of the adobe wall materials' durability.
