Earth masonry is a good alternative to more conventional materials in order to reduce the environmental impact of building materials. However earth construction techniques mostly rely on bricklayers’ experience, which is a hindrance to industrial development of this traditional know-how. This article proposes a methodology for the mix design of unstabilized earth bedding mortar based on mechanical criteria of the masonry and rheological criteria of fresh mortar. A test to characterize the shear strength of the masonry interface is specially investigated. The mechanical performances of the formulated mortar are then validated with laboratory scale characterization.

地基砂浆配合比设计方法

为了减少建筑材料对环境的影响，土石工是更传统材料的良好替代品。然而土方施工技术大多依赖于砖匠的经验，这阻碍了这种传统技术的产业发展。本文提出了一种基于砌体力学判据和新拌砂浆流变学判据的不稳土垫层砂浆配合比设计方法。专门研究了表征砌体界面剪切强度的测试。然后通过实验室规模表征验证配制砂浆的机械性能。
