Abstract: Soil-cement blocks also known as compressed earth blocks or stabilised mud blocks are used for load bearing masonry.
The paper focuses on the study of various characteristics of soil-cement blocks using highly sandy soils through an experimental investigation.
Characteristics of soil-cement blocks having three different cement contents (6%, 8% and 12%) have been examined.
Paper reports results of influence of cement content on compressive strength, tensile strength, IRA, water absorption, rate of water absorption, surface porosity and pore size distribution, stress-strain relationships and elastic properties of soil-cement blocks.
The results indicate that there is 2.
5 times increase in strength for doubling of cement content from 6%.
IRA decreases drastically with increase in cement content of the block.
Total water absorbed by the blocks is not sensitive to cement content of the block, whereas rate of moisture absorption greatly depends on the cement content.
Pore size decreases with increase in cement content of block, whereas surface porosity is independent of the cement content.
Soil-cement block modulus varies between 2000 and 6000MPa.
Elastic modulus increases by 2.
5 times when the cement content is increased from 6 to 8%.
Whereas the increase in modulus is marginal when cement content goes from 8 to 12%.
