Jul 20, 2006 0183 32 Some studies have shown that wet cutting methods can reduce average respirable dust levels by up to 94 percent However, if an employer determines that the use of a wet saw in a particular circumstance is not feasible, and the brick, concrete block or masonry must be cut dry, then the employer would be required to use another engineering ....

As moisture applies to all concrete, wet curing is a form of caring for newly-poured slabs Neglect a good cure, and you jeopardize the concrete , The challenge with this method is to keep the surface uniformly wet Dry intervals or patches can lead to crazing or cracking on the slab surface 2 Curing Blankets , This method is ....

The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln, whereas no water is added in the dry process...

Jul 17, 2019 0183 32 This is one of the most efficient methods of curing concrete Usually a spray from a hose pipe is used to wet the surface and the plastic is laid on, with generous laps at the joints Use timber or cement blocks to keep the plastic in position, rather than taping the joints To a certain extent the plastic can be used a few tim...
