Hi, I am a Civil Engineer used to design concrete mixtures. And these are my advices: 1- Make the mixture proportions 4 parts cement 6 parts sand & 9 parts gravel 2- use water about 30-35% of the cement by weight or roughly 45-50 % of the cement by volume 3- Use concrete superplacitizer about 1% of the cement by weight or about 1.5% of cement by volume. 4- Add 70 - 75 % of the water to the dry mixture and continue the mixing 5- Mix the remaining water with the placitizer then add to the mixture and continue mixing till you get homogenous mixture. 6- I recommend to add special fibre for concrete and you need to follow the manufacturer instruction. Normaly it is about 0.5 to 1 kg of fibre per 1 cubic meter. The fibre will act as reifircement. Regards Eng. Maki S Hussain - Iraq

Sorry, I dont agree on that water cemet ratio. And more importantly Why I think that the white cement one didnt achieve strength is that the aggregates were too round due to which the binding of naterials didnt take place. Where as the ready mix had mix angles of size and shape. Civil Engineer from India

Replacing 20% of your water with white latex paint would help with your tests and color. Latex paint increases concrete's flexural strength, and of course the white would make it a bit whiter. Great video tho!

@@joeyknight8272, I willingly admit that it's not one *I* came up with. About ten years ago my wife and I started a small ornamental concrete business, and in my research to find out if I could use latex paint as a means to dye concrete? I found out it's strength benefits as well. Concrete is part black magic, and part state secrets, and many folks closely guard both. I try to share what I know to be true as often as possible so others can, and hopefully, do the same.

the white in paint is Titanium dioxide, which you can purchase. You don'treally need the other stuff

also white rocks that were crushed instead of tumbled would be what you want.

Does this recipe cost the same as a 90lb bag of quickcrete?

So you want strong concrete ? Try to add poly fibres. Want a rock solid material for machinery or structural applications ? Try resin granite (5-10% resin).

The problem with the white gravel is that the cement wasn't able to bond with it as well. That's why you don't use smooth or dirty rock in concrete manufacturing. If you used clean and angular quartz or light limestone, your concrete would have been stronger and just as white.

Love, love, love this video Mike! Project videos are great but being able to see something like this massively opens the door and inspires a whole new variety of projects and innovations - super inspiring stuff and I hope you do more similar videos in the future!

Can't wait to see the concrete raw edge table!! Thanks for this video, Mike!

Sweet! Just what I was looking for. Thanks for sharing your results Mike! These tests are golden in my opinion. I personally wouldn't mind more of these types of videos from you.

This is the sort of channel you find at 4am and watch until it gets bright outside and then it comes up in your recommended for years to come

Excited for what’s to come!!! Coffee table, desk build!!

OH WOW! This was GREAT! We are totally making a concrete raw edge river table. Thank you so much for this video!

This was the most helpful video to show how different variables affect concrete! Demonstrating this made it much easier to understand. Thank you for making this!!!

I’ve been looking into making some white concrete pavers myself. This is excellent, thanks a ton!!! 😄

I've been digging through the internet trying to find a good video on mixing your own white concrete, and when you started the video off with all of the exact problems I am having, I was so relieved. The video was amazing, and thanks so much for putting this information out there!

Thanks for all of the great info. I liked this just as much as your full builds

So happy for you bro! I noticed that when I saw the video in my feed! Love your chill-vibe content. Keep going strong.

Awesome man! I've been looking forward to this video since you were talking about it on the podcast.

Awesome! Keep up the good work! Your videos keep getting better and better

so exciting that you're so close to 1mil! I have no idea how long I've been subscribed but its definitely been a few years. it's been awesome to watch your growth!

Brilliant save! Looks incredible.

Do more experiments! Love these kinds of videos and with you doing them makes it that much better! Just starting out and if I can save money by not having to do these myself would be awesome.

Awesome Mike, loving your take on a three point bend test :D

I've been waiting for this peppermint bark looking concrete video to be posted 😛😎🙂 TFS Mike...on Modern Builds 😁

Another certified banger! Your vids are getting better and better. Thanks mike!

That was a lot more interesting than I thought it would be. Good job Mike.

Great Work, Thanks for saving me a bunch of time !!

Great job on the experiment Mike! Thank you for sharing the video with us.👌👍😎JP

woah! i love this video so much. this is the reason why i like your channel so much. It really means a lot that someone takes the time to explain so much and in such detail

Great vid MM, THANX FOR THE TIPS

i always thought i needed a table saw....AWESOME now im gonna make my smaller projects on the floor :)

Nicely done Mike! 👍🏻👊🏻

Thanks for testing and sharing the results. Great video! Namaste! : )

I really enjoyed this. The concrete looks fantastic.

Totally enjoyed that experiment.

Interesting experiments, Mike! Good to know that mix.

That "The office" quote on the back is priceless. Great video!

Great video man! Keep up the great work!

love these types of vids!

This was awesome Mike!

thanks man I been looking every where for someone who was to try a white concrete counter top. Super help bro much appreciated!👍

Love this! Doing some work around the house this summer and I’m sick and tired of grey!

Looks fantastic

Awesome !!! Thanks !

Really enjoyed this video. Been thinking of doing a homemade modern bucket stool with white concrete so this really helped

Excellent experiments- learnt quite a bit . Thanks.

Amazing work man!

Excellent video, great service you are providing with this information

Great info! Thanks!

Thanks for that science lesson I found it very fun and I’d love to try it

A giant Spanish Turrón... Thanks for sharing this, I will do some garden steps. I really appreciate this.

Hey Mike, white concrete can be made by adding Ti02 or Zinc Oxide pigment in concentrations up to 10%. Both can be found at your local art store. TX Active cement bags have nanoparticle Ti02 for an ultrawhite finish. It's also self-cleaning to an extent.

Yes, get your EIN ready to speak to an Account Representative about buying 50 pounds of pigment direct from the manufacturer. 50g of Pigment is enough for a square foot of concrete. Getting 16oz (450g) of Gamblin Artist Grade Ti02 pigment from Michaels for $16 is more than enough for a couple of DIY projects.

thank you .it is very important information

I have absolutely no use for pure white concrete but I am now on the look out for something to make with it. This is sick!

Great video, I made a countertop with white concrete. I ordered my concrete online and it was terrible experience and also very expensive!!! Now I can make my own!!

thank you for sharing your knowledge I hope I succeed when I try it..

Awesome!

I love your style:)

Nice, interesting test.

The ultra white even without the strenghener would make a great counter top, with mesh of course , fab video

wow! thanks thanks thanks thanks! AND good job!!! I was just wondering about creating a nice whit-ish cement, but this is beyond my expectations. Your experiment will allow me (to make some more experiments) to be able to make (hopefully) a nice concrete countertop with the fibreglace re-inforcement and with a bit of flex to avoid breakage with acrylic and or resin... (tests needed)

Came up random. Left enlightened! Great video!

Omg obsessed with white concrete... had no idea it even existed.

Thanks for the content! I'm really interested in white concrete for making candle jars and trying to figure out a flame-safe way to do that!

that cheeky grin at 11:39.. hahahha

very informative

The mix is pretty similar to what ive been told by some guys working in a concrete factory, they were friends of our master carpenter. Try adding some different sizes of sand grains instead of one size, from coarse up to essentially powder, poor a thin layer and vibrate it, add GF to the rest of the batch and add it ontop of the surface layers. Ofc rebar and water replacments on final products. Thats how we made them and we got super smooth surfaces with dense concrete strong enough to support an IIRC 30-40cm floating edge. Cheers!

I use a jigsaw to vibrate the form. It works awesome. What i did was make my own white concrete like this but i used perlite. I made hundreds of fake stones and used them over my siding on my house. The perlite kept them really white and they were lighter. I made several different sizes but they all fit together to make a 4x8 panel. It worked out perfectly. It took about a month total time. I used construction adhesive to stick them to my house. I think it was liquid nails. They don't come off either lol. If you try, it will pull the siding off. After i glued them all on i grouted with some medium dark grout for contrast then sealed everything with a good concrete sealer. It looks so good my neighbors want it done. Guess im making more now.

the white concrete with the rocks in looks really interesting when broken into pieces, i could imagine chopping that up and gluing together to use for some very decorative walls or maybe even floor

Excellent

Hello from Cannes on the Côte d'Azur, thank you for these excellent and charming explanations 🤘🏻👍🏻. your friend is very lucky 😊….

Good shit, Mike

I wish you’d make something for outdoors using the pea gravel! The white aquarium rocks were fine, not ugly for sure but there’s something more beautiful (in my eyes of course!) about the off tone it provides and then to see the gravel after breaking it was just stunning! Especially in a natural setting as the natural tones of the gravel with the white of the concrete just feels more “natural” I guess. I’ve been wanting to build a play scape for my dogs whether that be different levels of exploration or using the land as my oyster, not totally sure yet as Pinterest makes it harder for me to decide lmao! I could see structures built using that gravel concrete to add a soft but neutral setting that wouldn’t look just like concrete jungles do. It’d be beautiful for outdoor furniture and indoors as well. The pure white again is fine but I don’t know I like that natural look and I feel like the regular gravel represented that beautifully
