Abstract

Abstract: In order to study the stress performance of modified raw adobe, modified adobes were made by different proportion clay, cement, and lime. The best proportion of modified raw adobe additive was found by a series of compression performance test. The results showed that compressive strength of modified raw adobe increased slightly with proportion of clay mass portion increasing. Compressive strength of modified raw adobe presented an upward tendency in a straight line with cement content increasing. Compressive strength of modified raw adobe first increased and then decreased with the content of lime increasing. The compressive strength of modified raw adobe was the highest when the mass fraction of lime was 18%. In general, the compressive strength of modified raw adobe was higher. The modified raw adobes, which had sintering-free, fast-forming and reducing-pollution advantages, could make up for the disadvantage of low compressive strength of plain raw adobes effectively.

Key words: new building materials, compressive properties, mixture ratio, modified adobe, clay
