Thanks for the laugh Mark. Seems I committed some serious woodworking sins. 😆 They were pretty old and dull already. I keep them around for just this kind of thing. Have a good day.
Hello Joe the tool guy and Chippa B, I'd like to say the mix ratio is missing due to crossed eyes, but truth is I didn't think about it at the time. I was only recording to show my brothers this project which I knew they would not attempt. It's clear now that would be helpful to other people doing their own test (which I'm hoping they do). If I run another test someday I'll make sure to weigh/measure all ingredients and list that in the video or description. To be honest I never pay much attention to cement/mortar mix ratios. I just add water until it feels right erring on the side of dryer rather than wetter. In this particular styrocrete test you can see it is quite dry with a pretty small amount of cement. By volume it is 70-80% styrofoam. The fiberglass is also a very small ratio. Just a small handful of chopped fiberglass, but I did separate the fibers by rubbing them around on a surface. I used a "very rapid hardening" RapidSet for the mix. It has small rocks which I screened out. Didn't use this one for a particular reason. I just had it handy. You might get similar results with regular Portland cement. If you want reduce weight then you might avoid anything with sand in it (like mortar mix). When I did this test I was contemplating making some outdoor furniture (in molds) and then covering with UV resistant epoxy. Another project I was contemplating was making large interlocking blocks which could be used to build a garden shed or similar. I tried Perlicrete also and preferred the much lighter stryrofoam style. One thing that was difficult was shredding the styrofoam by hand. If you are doing a big project you should consider an electric shredder of some kind. If either of you attempt a batch or complete a project with styrocrete please let me know how it goes or give me link to a video if you have it. Good luck.

No, unfortunately I haven't due to available time/other projects, but I'm still interested in documenting a recipe that works well at some point. I would also like to try making an outdoor large veggie/flower pot or something similar from a mold. If I do I'll try to share here. The video above I really only made for my (out of state) brothers as we were talking about it and I wanted to show them. You should give it a try. It wasn't hard other than shredding the Styrofoam into small pieces. Keep it pretty dry and I don't think you can go wrong. Add a small amount of shredded fiberglass if you want it to be quite a bit stronger. Good luck and please report back with your findings.
@@atubeviewer4942 best guess right without doing this again is....by volume: 80% styrofoam 10% cement 9% water 1% chopped fiberglass (separate the fibers by rubbing them around on a surface) I used a "very rapid hardening" RapidSet for the mix. It had small rocks which I screened out. Didn't use this one for a particular reason. I just had it handy. You might get similar results with regular Portland cement. If you want reduce weight then you might avoid anything with sand in it (like mortar mix). If you have time/materials give it a try with different ratios and then do your own destructive testing (or whatever testing you like). Report back your findings if possible as I'm interested to hear how it went.
"Hey!!..how come my wood chisel is so dull? It was razor sharp last time I used it!!"..
"..and my hand saw!!"

Mix ratio?
Be handy wouldn't it 😉

You failed to provide the recipe.

re styrocrete; You didnt do anything past this?

@@smittyvidsstudios3755 Do you remember what all went into it? Shreaded styro, fiberglass,, what else and how much of each?
@@atubeviewer4942 best guess right without doing this again is....by volume:
80% styrofoam
10% cement
9% water
1% chopped fiberglass (separate the fibers by rubbing them around on a surface)
