When trying to decide what type of sealer you want to use you should ask yourself three things. First, what amount of maintenance do you expect? Are you willing to clean the floors occasionally and apply more coats as needed, or are you more of a “one and done†person when it comes to maintenance? Secondly, what are you expectations?
Though concrete hasn’t always been as strong and durable as it is nowadays, it has been around for a really long time. There’s actually even an account of concrete made by nature itself over twelve million years ago.
Self healing concrete, sounds impossible right? Well, guess what? …Self healing concrete actually exists. Concrete cracks, most will argue that it’s to be expected. No matter how much care is put into reinforcing or mixing concrete, it will eventually cracks. In some situations cracked concrete can lead to collapse. Professor and microbiologist, Henk Jonkers from Delft University of Technology in the Netherlands has come up with a new innovative type of concrete that actually heals its own cracks.
Grinders have discs that rotate horizontally to perform various duties, from removing paint and thin coatings to lightly texturing to allow the surface pores to open. The reason they are so versatile is because of the different grinding attachments. The attachments come in various types and grits to allow for multiple applications. Since grinders use rotation instead of impact to remove material, the amount of material that can be removed is restricted to about â…› of an inch, this also depends on which type of attachment is being used.
How do you know when to apply a chemical hardener? All concrete is different, and it’s best to evaluate each substrate before you apply a densifier. Some say that the only time to apply chemical hardener is during the polishing phase after the stain or dye has been applied, as well as after the 200-grit resin-bond diamond has made its passes.
Yes. You read that right, electricity conducting concrete. Researchers at our very own University of Nebraska-Lincoln have been working on creating a new type of concrete that is able to conduct just enough electricity to melt snow and ice safely. This new formula resembles the formula for regular concrete, but has been adjusted to contain 20% steel shavings and carbon particles.
