  • Concrete

    I know that this is not a welding project, but I would just like to show you what I have been working on! I started a business making pre-cast concrete countertops. Here are a few pictures of finished products!

            They look great! How did you learn the process? Is it difficult? I was thinking of doing a concrete counter top for my bbq island.

                I went to The Concrete Countertop Institute in North Carolina. It is an awesome class that will teach you everything from the structural engineering of countertops, to concrete mix formulas, forming, grinding, finishing ecc… after taking the class you will be able to make a superior countertop surface.

                        I was thinking it would be cool to make a concrete surface to mount my 8x24 table-top lathe. I figure that would clobber any chance of vibration. Ah yes, another project.

                          Another Project

                          This is my kitchen countertop. Industrial Grey, with Under-Mount Sink, and Integrated Drain Board. Also note Stainless Steel Backsplash made from scrap i picked up from the recycling center and treated with a 3M pad.

                            "Counter-Point"

                            Jesse: Those all look really nice. How much does that kitchen counter weigh? Do you use 3/8" rock and mix the color in the batch? 2500# mix?
                            As the counter top will be subject to water, do you add entrained air in your mix?

                            The outdoor types are very popular out here in Phoenix.

                            Again, looks great, like a granite top!

                              Info

                              At this point we are using CSA (calcium sulfoaluminate) Cement with a water to cement ratio of 0.35. This gives us compression strength of 10,000psi. As for aggregate it is all the Clients choice. We usually use a standard pea-gravel mix (many sizes of stone) because this will produce a denser mix. Small Stones fit between large stones. But we can also replace the stone with Colored Glass pieces as seen in the desktop picture. Or subtract it all together (use a sand mix) to get the desired look that we are going for. Color is added in the mix using natural or synthetic pigments. It is colored all the way through!. This means you will never have to worry about the finish rubbing of, as with staining. There is also Glass Fiber Reinforced Concrete where you use structural rated glass fibers in place of the stone. This will also produce a stronger lighter mix. NO entrained air! In fact we use plasticizers and other methods to get a “fluid mix” to reduce air pockets, and improve workability. All Countertops are sealed with a onetime epoxy urethane sealer that is impenetrable to water and most staining agents.

                              Standard for weight is about 18lbs a sq. ft. at 1.5 inches thick.

                              Concrete is not for everyone, bit is is another choice that is out there! It is highly creative and you can personalize it for a client. And because it is hand crafted from scratch is is somewhat costly. I
