Recipe to make the strongest concrete, called Ultra High Performance Concrete (UHPC)

This video provides the recipe to make the strongest concrete called Ultra High Performance Concrete (UHPC). The cost of commercially available UHPC is very high. However, the cost of open source UHPC, as you will learn in this video is fraction of commercially available UHPC, with similar characteristics to most of the commercially available UHPC. UHPC is more than five times stronger than the currently used conventional concrete in building and bridges. One of the best characteristics of UHPC is its superior durability. You can make pool out of UHPC and use it to store a very hazardous materials. It is that strong. To make UHPC using the open recipe that you will see in this video you will have to do some experiments using local materials, but in a short time you will be able to produce a UHPC with excellent strength and durability.

Very informative

Profesor thanks so much for this wonderful information, I am doing a quick calculation of the mix design shared and I am getting about 6% of fiber, it is correct? ✅

there is tow type of sperplastisizer ?

درود استاد عزیز، اگه کامنت من رو میبینید ممنون میشم راهنمایی بفرمایید🙏 من میخواستم برای بیس یه دستگاه سی ان سی فرز از بتن فوق توانمند به جای ریخته گری چدن خاکستری استفاده کنم که جدیدا شرکتهای بزرگی دارن سمتش میرن ولی متاسفانه شخص آگاهی رو حتی در مراکز آکادمیک داخل کشور پیدا نکردم، ممنون میشم راهنمایی کنید که آیا این ترکیب جوابگو هست یا خیر برای همچین استفاده های حساسی؟ 🙏❤️

So after the original point of failure the monitor started to display the lb/s as decreasing(-lb/s). Was that the press itself letting off and preventing further failure?

The maximum applied stress was about 19,000 psi to a 4 by 8 inch cylinder. This particular machine applies load by controlling the displacement. After reaching maximum load capacity, specimen, because of steel fibers, still had some capacity and that is why you saw decreasing load. Most common way of testing concrete cylinder is using load control. Under load control machine tries to apply a load and if specimen fails, the failure will usually coincide with loud noise. In the case of UHPC because of steel fiber even under load control the failure does not appear as brittle as normal concrete case.

Almost 20,000! I wouldn’t want to be standing around that lol. Thanks for sharing this. I’m a carpenter and I want to experiment with some of my own projects in the future. Been down the YT rabit hole looking at aircrete and domes and found you on IG. I wonder if this could be crossed with something like aircrete and use fiberglass fibres and still achieve higher strengths (albeit not as strong) with lower cost. Cheers!

How long was the current of that pillar?

[@kubabuda]

@@Atorod_Talks 19,000 psi on fi 4in is 161 MPa? nice

Are those steel fiber whire EDM cnc leftovers?
