System Balance Problem Of Mixture After Concrete Pouring For concrete with heavier bleeding and segregation, the mixture system is an unstable system. Because of the large water-filled space, the mixing water filled with the water-filled space can’t sustain the weight of the system. Under the effect of its own weight, the spare mixing water is squeezed out until the water-filled space is small eno...

Concrete surface preparation is the first and most important step for the installation of any flooring. Without proper concrete surface preparation, many problems can arise once you install your new flooring system. If you have ever seen uneven floors, peeling floors, or bubbling floors, it could be because the floor was not prepped properly. Every surface needs to be cleaned, open and porous for ...

With concrete grinding, the diamonds cut into it and scratch it away breaking it down to sands and dust. During this process, the diamonds fracture and wear down, but at the same time, the bond metal is worn away by the dust of the concrete which exposes more of the embedded diamonds so that cutting can continue. When grinding hard concrete, the diamonds cut, blunt and break with much less cutting...

Synthetic diamonds are an essential ingredient in the success of a surface preparation project. Concrete grinding diamonds are available in a wide variety of shapes, sizes and strengths. Size is classified by the mesh or grit number. Generally, a large diamond has a small number while a smaller diamond has a larger number. While larger diamonds are used to expose the aggregate, smaller diamonds wi...

For decades, concrete floors were considered functional and durable at best, with no perceived aesthetic value. Today, polished concrete is among the most popular flooring alternatives due to its unique stone-like appearance, eco-friendliness and cost-efficiency in terms of maintenance. While a grinder is an important piece of the puzzle to producing concrete floors, the real workhorse of any grin...

As the dust from hard concrete is soft and unabrasive, the metal matrix that the segment is made of needs to be 'soft bond' and easily eroded to expose the diamonds. Often having a coarser grit can be beneficial because it may produce coarser dust to help erode the matrix. In addition, reducing the contact area with fewer segments makes a difference. This also has the effect of increasing the weig...

Grinding soft concrete requires 'hard bond' grinding discs that resist the metal matrix being eroded away. The sandy, gritty, abrasive dust will erode diamond grinding discs abnormally fast, so be certain that you are using the right diamond grinding disc. More than any other time, grinding soft concrete is when contractors need to be aware of the signs of rapid grinding and fast wear to stop work...

There is a simple step-by-step process you need to follow if you want to get the perfect polish on your concrete. It involves the obvious grinding and polishing, but you need more than just a good floor grinder or good concrete diamond tools if you want to optimize concrete floors to be all they can be. The basics of concrete floor grinding & polishing Grinding concrete might sound complicated...
