Rammed Earth with Sandy Soil  RSS feed

Hello,

I have a sandy soil (80% Grave and Sand) with gravels less than 4mm, with very low clay (I understand from tests).
Can a good rammed earth wall constructed with cement? I have difficulties in importing soil with more clay to mix with?

Thanks
Guru

Hello, the answer would depend on the conditions you need to withstand.  Can you provide more info about the design of the building?

Thank you.

We are talking about a two-storey building of 1300 sqft. The foundations are made of natural stones. Walls are supposed to be one foot in width.
I need to build 3 feet retaining wall.
The soil mentioned could not be rolled up to 3mm but it has little clay it seems. I have made some test blocks with 10% portland cement. As of the third day the blocks look pretty good. I am planning to test for compressive strength after seven days. My question is, the compressive strength, water absorption, and erosion test are satisfactory, can I go on using the soil?

I just want to make sure that I am not committing any mistake

PS: The wall height proposed is 10 feet. It is most likely to have RCC roof  and we have a dry climate except two months of monsoon

Thanks
