I've got access to a pretty much limitless amount of cement. I want to start doing experiments with it. Something I want to do is try to do toys or jewelry or table top decoration casting 3d printed molds. For that I need the finished pieces to be a) smooth surfaced b)Small but structurally solid c)able to retain good resolution on small details. 

Anybody tried this before? What aggregates could should I try? I'm thinking some type of resin but I literally have no idea. Any books? manuals, papers I could take a look to? Forums to visit?

fibre reinforce

I'd look into making custom landscaping sculptures. May be bigger than you're thinking, but I'd bet there's a lot of internal structuring information to be harvested.

Thanks for your responses.

The obvious answer is for smaller forms you use smaller aggregate, smaller gravel needs different amount of sand, mixing concrete is an incredibly in depth subject you can waste weeks researching different things. Silka has a concrete handbook that outlines all of the basics, your country should produce a standard that details the standard mixes acceptable for various purpose. You can readily find strength mixes online however low strength mixes c15, c20 are so shitty that it doesnt really matter what you put in it you will succeed which is why they let you batch it by volume instead of weight.

Fibre reinforcement really only stops cracking due to shrinkage it doesnt add a lot of strength. Rebar or mesh form will give some strength other than compressive which concrete is good at.

I wouldnt bother with many forums, most people dont care about nuanced mixes and only talk about low strength. High strength or prescribed mixed are normally industry secrets good luck getting actual recipes. But there are many many peer reviewed papers to read on specific subjects

Concrete dildoes.

check etsy, people sell all kind of molded deco shit to retarded women for a lot of money, like candle holders, table lights molded from a coke bottle and shit i kid you not

It’s pretty common to make speaker enclosures out of cement. 

I’v even seen concrete boats.

hoenssty ag fag here

if you make giant cement pots 

you can sell each one for 100 to 500 bucks

like a 5 gallon one will go for 80 or so

then it goes up 

those ones for palm trees can got for a few k

Start a ready-mix company, retail prices are $1,000 to $1,500 a yard and you took out one of the highest-cost items

Precast pavers.
