How To Make White Concrete | A Modern Builds Experiment

  • Published on Jun 20, 2019
  • How to make White Concrete for the best result in your DIY furniture projects. White concrete is something I've wanted to incorporate into my videos for a long time, but it's not readily available in most places and expensive to acquire online. The good news is that all the individual ingredients are locally available and super affordable. See best recipes below :)

    Sorry, but you need to wait about, at least 7 days to cure the cement, so you can do some test... Just a tip... Good luck!!

    Would have been interesting if you had added rebar to another experiment so we could see how it would hold up as a countertop.
    Love white concrete!

    Concrete strength is tested after 27 days and always in a cubical form. Look for more info on grades of concrete - M20, M30 etc

  • Nitesh kumar Prajapati

    I wanna know why you don't get a comprehensive strength test device for accurate measurements bcz they definitely have different strength to each other & if their strength are know n improve they can be used in various DIYs differently..... 😏

    Wonder instead of aquarium gravel using white marble chips (landscape section). Would want to wash the dust off before adding. I thik the stones of the aquarium rock are too small however, I could be thinking wrong. I did find this whole video super helpful though as I'm formulating doing my own kitchen counters in May or June of 2020.

    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)

    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

    Why don’t you put the white cement and and white gravel with fortifier in first, and move it to the sides. Then put the pea gravel mix in the middle. That way you get the look you want on the top and edges. Then in the middle you get the strength.

    Could you use this for countertops or is it too fragile?

    • dlr
      dlr 4 months ago

      Upon researching I have found out that you can use this for countertops but halfway through filling the mold you need to put in rebar or some sort of metal mesh to support the inside of the concrete. Fill in the rest of the mold like normal and they will be strong enough for countertops. Answered my own question 👌🏼

    It's a cool video, but I don't understand what the point of having white concrete is... I guess if you wanted to make countertops or mayve in your backyard, just seems very niche

    I like everything about your channel except for one thing, the way you say "Modern Builds" in your intro. It's like you try to sound like the TV show's intro, and I think with your voice and character, it's lame. Every time I heard, it makes me wants to stop watching the video even though I really like your works.

    You can get even whiter concrete just using standard concrete mix and adding about 5% titanium dioxide. Ends up looking great, really white. TiO2 is used in soap making so it's really cheap. Since you only need 5% shipping is more manageable

    Bro next time, use a one by one or something like that to pack the concrete, and use the sander instead of hammer

    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.

  • Steven Donati

    I’m a terrazzo specialist , you should put steel rods into your forms , steel makes it 10 times stronger . Plus you should have put marble dust instead off sand . When you polish it up it won’t egg shell , you ratios are totally wrong . The ratio for terrazzo is 1 kilo cement to 2kg aggregate , 550 ml water 200 grams marble dust , your steps will curl and craze the way you made them

    The more gravel the more strength. For instance 4 - 2 - 1 would be even stronger than 3 - 2 - 1.

    Thank god you aren't using melamine for making furniture Whew, Almost got mad there, Never make furniture out of press board NEVERRRR MAKE MELAMINE PARTICLE BOARD FURNITURE, IT SUCKS. Great for molds and other Non furniture uses...

  • Bobby Patton

    Most of those cheap aquarium rocks are often coated and do have any porosity, and I would suspect that is why it was weaker, the cement paste can't bond as well to the impervious coating.

    curing it under water for 28 days makes it stronger and you would get the final strength

      That's not correct with modern concrete unless it is specifically designed for placement underwater.
      And even now--bridges with concrete piers--the water is evacuated from the area for the placement to occur.
      You are thinking about the concrete that was made during ancient Roman era, which is very different than what we use today.
