    Concrete Grinding Machinery. Concrete grinding machines are a heavy duty that has disks fitted with diamonds to grind tough concrete surfaces. The grinding blades can be replaced by finer and finer grinding blades to smooth out the surface.Due to the high price value of the blades you wouldn’t find small concreting companies owning such a machine, they rent it on demand. We have it with us, so

  • The Dusty Dangers of Concrete Cutting & Grinding

    Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are dry-cut they release silica containing dust into the workers’ breathing zone. Regular exposure to this hazardous dust can

  • How Much Does Concrete Grinding Cost Per Square Metre

    The cost of concrete grinding is affected by five key factors; Size of the floor; As you’d expect, the larger the floor, the less you’ll pay. This is due to the economies of scale. When determining the cost per square metre, the contractor will ask you to pay more for a small floor project (less than 50,000 square feet). Design complexity; Complex projects generally have a higher cost

  • CDC Silica, Engineering Controls for Silica in

    09/07/2018· Construction workers who perform concrete grinding may breathe dust that contains respirable crystalline silica (RCS). A NIOSH Cdc-pdf [1] study found that workers grinding concrete to smooth poured concrete surfaces were exposed to high levels of dust containing RCS, ranging from 35 to 55 times the NIOSH recommended exposure limit (REL). The Concrete Grinder without Engineering

  • Control of Hazardous Dust When Grinding Concrete

    Construction workers are exposed to hazardous dust when using handheld electric grinders to smooth poured concrete surfaces after forms are stripped. The National Institute for Occupational Safety and Health (NIOSH) found that exposures could be reduced if a local exhaust ventilation (LEV) shroud was attached to the grinder.

  • OSHA Silica Standard Concrete Floor Grinding Dust

    Concrete Floor Grinding is covered in Table 1 of the regulation. According to the standard, you do not need to measure workers’ exposure to silica or provide respiratory control if any of following criteria is met: 1) Use a machine equipped with an integrated water delivery system that continuously feeds water to the cutting surface. Table 1 does not specify a minimum flow rate; however

  • Controlling Dust When Using a Grinding Wheel on

    Using a handheld grinder for repointing indoors or in an enclosed area requires an exhaust method, such as a portable fan, as needed to minimize the accumulation of visible airborne dust. Be sure that any exhaust method chosen moves airborne dust away from workers and does not block an exit route.

  • POLISHED CONCRETE FLOORS ghana all concrete floor

    Many in the industry do not consider a 3 step grinding to be truly polished concrete. The 3 step process is often referred to as a hybrid polished concrete. This polishing can be done wet or dry depending on the site situation. Benefits of dry grinding include dust free operation and easier clean-up since no slurry is created during the process. However dry grinding can expose workers as well as the HVAC system to

  • Respirable Crystalline Silica Dust Exposure During

    A total of 49 personal respirable dust samples were collected during concrete finishing while workers used hand-held grinders. Only 15 (31%) of the grinders were equipped with local exhaust ventilation (LEV) systems. The confounding factors (e.g. wind velocity, wind direction, relative humidity and ambient temperature) were determined. To make the sampling task-specific, air sampling was
