concrete canvas / cement fabric

I was wondering if anyone had experience making walls / roof tiles possibly out of fabrics coated in concrete. I have seen some old posts here talking about coating old carpet in concrete to make a roof but that post was well over 10years old.

I have recently started using polypropylene landscape fabric (Vevor 8oz non woven landscape fabric) to make some 'planters' that I will be leaving out side over the winter to test its durablity to weathering and freezing.

I have currently tried store bought mortar mixes, as well as straight portland cement also somtimes adding acrylic bonding agent into some of the mixes.

I make a wet slurry mix of concrete in a bucket and just dip the fabric in and shake off the excess

This idea is inspired by:
George Nez's latex concrete habitat

and a youtube channel called: Paradise Builders-Ideas Frescas Ecolodge where he does almost this exact thing to make plant pots

If anyone has done this and has any pointers / ideas or questions feel free to comment

Thanks  

Where are you located, it helps with replies.
I have seen what you are talking about.
It involves are larger container filled with a liquid form of mortar into which the cloth is dipped for a full coating.
The cloth is then draped over the formwork or frame that will cretae the shape and maybe hold it in place permanently.

As A Civil Engineer I must advise that concrete and mortar are tow different things.
Mortar consists of usually portland cement and sand.
Concrete consists of portland cement, sand and aggregate.
They are used for entirely different tasks.

I have only tried mortar mixes and straight portland cement

I have found that lower concentrations of sand seem to work better, too much sand and it doesnt stick to the fabric when you pull it out of the bucket, also mixing in some acrylic bonding adhesive helps keep the slurry on the fabric while putting it into place
