How to Grind the Soft Concrete?
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 and rectify the problem.
Things need to noted when grinding soft concrete
1. Inspect your diamond tooling regularly for unusually high diamond exposure.This means that when you run your finger over the surface the diamond grit is sticking out a lot.The diamond grit will befalling out of the matrix before you have had a chance to wear them out.
2. Use diamond tooling with a hard bond and or more segments to grind. And be certain to remove the machine weights during grinding to reduce the weight on the diamond tooling.
3. Use a vacuum that will extract dust away as quickly as possible.This will greatly improve the life of the diamond tooling. If there is a lot of dust rolling between the floor and segments, it will cause excessive wear of the diamond tooling.
Tips for grinding soft concrete
● Do not use the cheapest diamond grinding disc and expect to save money, it becomes an expensive exercise. A premium diamond grinding disc is usually the best value for money.
● Reduce the weight on the head of the machine as much as possible to ensure that the sandy, gritty, abrasive dust that is rolling around under the segments does not erode the matrix any more than necessary.
Make the rough and dirty terrazzo become smooth and bright and achieve a mirror effect. This process has a low cost of refurbishment. No pollution, no dust, no muddy water splashing or noise during construction, such as shopping malls, hotels construction can be carried out while operating. It can also change the traditional floor construction technology, for example, the floor can be paved with a rough board or squeezed and then polished. Not only can the cost be reduced, but also the splicing joints in the construction can be eliminated.
