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.

Ilangovan et al. (2008) [9] reported that the strength of quarry rock dust concrete was comparably 10-12% more than that of
Use of substitutions like offshore sand in particular to replace river sand is on the rise. Quarry dust is another alternative for river sand. However, full replacement of river sand with quarry dust is viewed with scepticism. Possible loss of workability and increase shrinkage is sighted against use of quarry dust as fine aggregate in concrete.
Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials.
These alternative aggregates can be used in concrete production as they are economical and naturally available. ... The use of lateritic sand in combination with quarry dust can help to achieve this purpose and impact ... proportions and the best results as per the standard grading are as shown in the table 3 below.
Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. It is used as substitute to sand to make concretes, which are believed to be stronger and more durable than the regular concrete materials.
alternative for river sand. It is done by using quarry dust to replace natural river sand by . They decided to cast m25, m30, m35, m40, m45, m50, m55 and m60 concrete grade cubes with one set using natural river sand and other set using quarry dust.
M-sand and quarry dust. The quest for alternatives to sand has led to the growth of the manufactured sand industry. The product, also called m-sand, is made by crushing granite or basalt rock to a required grain size. It is considered better than sand as it lacks the inconsistency and impurities present in natural sand.
the study is to replace the sand partially or fully by Quarry stone dust or Foundry sand in mortar as in future there will be depletion of sand. Hence, it is necessary to find inexpensive and easily available alternative material to Natural River Sand. Key words: Quarry Stone dust, Foundry sand, Compressive strength, Tensile strength
Quarry dust is another alternative for river sand. However, full replacement of river sand with quarry dust is viewed with scepticism. ... Results indicate that quarry dust can be …
The aim of this research was to find the best alternative for river sand in concrete. In both geopolymer concrete (GPC) and cement concrete (CC), the fine aggregates are replaced with various sustainable mineral ashes, and mechanical and durability tests are conducted. Specimens for tests were made of M40 grade GPC and CC, with five different soil …
quarry dust instead of sand. Apr 20 2010 · Hi all please help if you canWe are in a process of putting a new sandstone paving down instead of old large concrete slabs Our landscaper has cleared all the old slabs off and underneath is what he calls quarry dust and hard packed type 1 He says quarry dust is the best stuff to have under He proposes to level off the ground …
Some alternatives materials have already been used as a replacement of natural sand such as fly-ash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].
The sea sand taken from the off shore area has low salinity level than sand of beaches, so can be used as an alternative.

Stone dust is a fine material that absorbs moisture readily, then releases it slowly. The same properties that work wonders for organic gardening can wreak havoc underneath pavers, causing efflorescence and allowing them to settle or shift easily under load. In extreme frost-thaw cycles, water-soaked stone dust can actually pump up through the ...
The result of quarry dust as a replacement for fine aggregate presented in Figure 4 shows that the Schmidt rebound number increases with an increase in quarry dust at all curing ages. When compared to C 30 and both concrete with alum sludge contents, it is seen that result for concrete with quarry dust was higher.
natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. 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.
