Use soap and water to wash off dust to avoid skin damage. Wear a P-, N- or R-95 respirator to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid ingesting cement dust.
A road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway.In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course.Road surfaces are frequently marked to guide traffic.
» how to calculate cement sand gravel ratio in m15 for 1:3:6 pcc Portland concrete, the basic ingredient of concrete, is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients to which gypsum is added in the final grinding process to regulate the setting time of the concrete.
Quarry dust has been proposed as an alternative to river sand that gives additional benefit to concrete. Quarry dust is known to increase the strength of concrete over concrete made with equal quantities of river sand.

It is not possible to make concrete out of quarry dust, since quarry dust is a waste product that is produced during M Sand / stone crushing process. To make concrete, it is necessary to make use of sand or M Sand (An alternative for river sand).
Use of Quarry Dust to Replace Sand in Concrete ... The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures.
The effect of quarry dust on the flexural strength of concrete has been experimentally studied and reported in this paper. Concrete used was prepared by replacing 25% and of sand by weight with quarry dust.
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Concrete sand's coarse texture prevents problems with drainage and creates friction that helps lock pavers into place. It compacts easily by hand or with the use of a mechanical compactor.
When selecting the type of sand to use for your bedding layer, you should look for a material that is somewhat sharp, course, granular and features grains of sand in similar sizes. This is because, as you work to compact the bedding sand, you want the edges to grind together and lock it into place.
