Experiment of Compressive Strength of Plasticity of Fresh Lime Mortar For Arch Joint Study of the freehand applied construction method of the tunnel vault No.2

摘要

We made the arches of rectangular bricks by using lime mortar for the joints. Lime mortar works as joint adjustement between rectangular bricks. For making strong arch as a kind of shell we removed the centering of arch as soon as bricks were finished to lay and did compression. This way is called a freehand applied construction method. Here this experiment causes questions about the strength of the fresh mortar. This paper concerns to the experiment about the compressive plasticity of lime mortar.
