Size Effect of Masonry Joint on Compressive Strength of Stablised Mud Blocks

Abstract

Size Effect Of Masonry Joint on Compressive Strength of Stablised Mud Blocks (SMBS) are manufactured by compacting a wetted mixture of soil, sand and stabilizer in a machine into a high-density block. Such blocks are used for the construction of load bearing masonry.

This paper focuses on some issues pertaining to strength of stabilized mud block masonry, both dry and wet, the effect of the strength of five cement mortar mixes and two soil-cement mortars mixes using stack-bonded prisms. A systematic experimental investigation was undertaken to know the parameters affecting the strength of masonry in cement mortar of different proportions and soil-cement mortar.

Conclusion

The wet compressive strength of stabilized mud block and masonry prisms is less than the dry strength. The wet and dry strengths of these masonry prisms decrease with decreasing mortar strength. The masonry efficiency of stabilized mud block work in wet state is 0.52 to 0.21 and the Value in dry state is 0.39 to 0.22. The ratio of Wet Prism Strength to Dry prism Strength varies from 0.50 to 0.36
