Building small objects out of concrete Answered
I was wondering if i could get any pointers on mixing concrete, I have gone through the concrete mixing instructables already and have not found anything suitable and hence I am asking her. I want to formulate an open recipe to make concrete objects like the ones in the following links,
They are mostly small objects where the wall thicknesses are quite small (maybe a few mm). I think it will be interesting to see a DIY approach to making a concrete composition that is strong in small thicknesses, i think a lot of cool objects can be made from it .
I have tried the normal concrete mix with cement and sand but i am not able to get it strong enough at those small thicknesses. Can anyone please some suggestions or advice on how to go about this ?
Thanks in advance, please see attached files for some images taken from around the web, i do not own any of them.
