Linear Shrinkage Behaviour of Compacted Loam Masonry Blocks

| description | Walls of wet loam, used in earthen houses, generally experience more shrinkage which results in
cracks and less compressive strength. This paper presents a technique of producing loam masonry
blocks that are compacted in drained state during casting process in order to minimize shrinkage. For
this purpose, loam masonry blocks were cast and compacted at a pressure of 6 MPa and then dried in
shade by covering them in plastic sheet. The results show that linear shrinkage of 2% occurred which
is smaller when compared to un-compacted wet loam walls. This implies that the loam masonry blocks
compacted in drained state is expected to perform better than un-compacted wet loam walls. |
