Cement mixed with Epoxy Resin experiment.

First, let me say that it works! So if you are here its most likely that, like me, you looked online to see if someone had done this experiment yet and found very little. I did find lots of people asking and talking about everything else they tried except this! Lots of people layered cement and epoxy but not actually mixed it. ​

First I tried approximately ( everything is approximate!) 65% epoxy resin ( art resin) and 35% cement ( cement all quick setting) I mixed my epoxy first as per instructions and then I added my cement powder right in. (no water added) It worked super well. It came out darker and it sort of look like wet cement. It feels more like resin then cement and took a good 24 hours to fully cure.

For m second try, I used the reverse so 65% cement and 35% resin. This time I mixed my cement as I would have normally except I kept it on the dryer side (a bit less water then I would normally). Then I mixed my resin as per instructions and mixed both substance. Again here it worked like a charm! This time it looks a but more like cement would and took a bit less time to dry although it still takes much more time then just the quick setting cement all. See picture above of the 2 resin mix with cement experiment. Darker more resin looking is the first try and second is this new ratio.

I finally tried with even less resin to see if I can get that real cement feel ( grainy and sand feel versus the resin with is more plastic). I tried a 90% cement versus 10% resin ratio. It made the casting strong enough that my object did not break when I pulled it out of the mold and it feels like cement. Yay!! Here is a picture ( below) of the 3 different ratios although I don’t think it really shows.
