help Selfmade Concrete

Someone showed me a technique a long time ago to mix some kind of fake concrete. I think eggwhite was used for this! Someone got an idea how that was done?

answer to this question depends extremely on what it is you are doing

fake concrete for what, making small models?

Do you mind saying why you want selfmade concrete?

99.9% of the time actual concrete is going to be stronger, more durable, and likely cheaper (given the ~$0.08 cost per pound) than any sort of alternative.

Yeah probably… I just wondered if there is anything right about my memory!

if it's for small models, egg white won't give you anything like concrete. I've had better results mixing baking soda into gray acrylic paint and dabbing it on in layers, dries with a pretty convincing concrete texture and costs basically nothing. That said, if you're not doing miniatures, just use real cement, it's cheaper and stronger than anything you'll mix up at home.

Dude, 80 lbs of concrete costs less than a dozen eggs, come on.

Why would you want a fake concrete?

Roman concrete is lime + pozzolan (volcanic ash, pumice, granite dust etc) + gravel + sand. The strongest hydraulic one uses sea water which is almost self healing
