Production and characteristics of stabilised interlocking mud blocks
View through CrossRef
Abstract
This paper presents an ideology over physical and mechanical properties of interlocking and non interlocking stabilised mud blocks. These properties are useful to assess the performance and behaviour of load bearing masonry structures. This paper also compares the results of both non interlocking solid stabilised mud blocks (NSMB) of size 230 X 190 X 100 mm and interlocking solid stabilised mud blocks (ISMB) of sizes 230 X 190 X 80 and 230 X 190 X 70 mm. These blocks are tested for block density, Initial rate of water absorption, water absorption, wet compressive strength, flexural strength and Modulus of Elasticity. From the results obtained it has been found that shape and depth of interlocking has significant effect on properties of blocks. Flexural strength of 20mm (ISMB 20) and 30mm (ISMB 30) depth interlocking solid stabilised mud blocks produced are very much comparable with NSMB. Flexural strength of ISMB’s has been tested in both the directions of interlocking effects of blocks which has given satisfactory results. This test shows that Shape considered for interlocking blocks do bond well with filler materials. Mechanical and physical properties of both ISMB and NSMB have exceeded the minimum requirements of blocks as per codal provisions.

This paper presents an ideology over physical and mechanical properties of interlocking and non interlocking stabilised mud blocks.
These properties are useful to assess the performance and behaviour of load bearing masonry structures.
This paper also compares the results of both non interlocking solid stabilised mud blocks (NSMB) of size 230 X 190 X 100 mm and interlocking solid stabilised mud blocks (ISMB) of sizes 230 X 190 X 80 and 230 X 190 X 70 mm.
These blocks are tested for block density, Initial rate of water absorption, water absorption, wet compressive strength, flexural strength and Modulus of Elasticity.
From the results obtained it has been found that shape and depth of interlocking has significant effect on properties of blocks.
Flexural strength of 20mm (ISMB 20) and 30mm (ISMB 30) depth interlocking solid stabilised mud blocks produced are very much comparable with NSMB.
Flexural strength of ISMB’s has been tested in both the directions of interlocking effects of blocks which has given satisfactory results.
This test shows that Shape considered for interlocking blocks do bond well with filler materials.
Mechanical and physical properties of both ISMB and NSMB have exceeded the minimum requirements of blocks as per codal provisions.
