More Info On Aggregates

In concrete mixing, aggregates influence water consumption rates; affect the thermal mass quotient in concrete; add to water resistance capabilities of the concrete; and are crucial in fortifying concrete. As the most important factor in making the concrete mix voluminous, its shape, size, and texture leave an indelible impact on shrinkage, durability and the workability of concrete.  From being chief component in concrete mixtures, to being mulched around trees and plants as decorative gravel or restoring depleted soil layers as top-soil in gardens or as infill material for a new lawn—Aggregates fulfil a variety of roles in construction and landscaping.

As Sand and Gravel

In addition to its well-established position in concrete mixtures, sand is an inseparable ingredient of the brick making process, its sharper form—the pit sand which is courser in comparison to other varieties of sand is a staple in masonry work. Screeding sand a much finer specimen than pit sand is common feature in plastering, rendering, and mortar work.  Jointing work witnesses regular beach sand or washed sand in paving assignments; aside from the beach, washed sand is a popular surface ingredient for recreational areas involving children and leisure activities. On slippery roads, during winter, gravels enjoy greater thawing advantage over sand, offering traction assistance to vehicle drivers in negotiating difficult driving conditions. Gravels are also popular as accessories in landscaping driveways for its porosity and equally popular for its ornamentation value in housing projects with gardens and backyards. Its filtration properties are well-known and often put to use in water purifying projects as well as in the treatment of waste water. Tarmacs layers in road building are usually supported by strong layers of gravel at the ground level.

Crushed Aggregate and Topsoil

Procured from construction sites as excess material or as concrete waste resulting from demolition work, crushed aggregate or concrete aggregate falls in the recycled category and is an excellent ingredient in the load bearing layer of pavements and walkways. Keeping its place reserved as filling material in concrete layering of the base level for ground floors, crushed concrete as an aggregate is also applied at the base of garden beds for imparting elevation and thereby enhancing its drainage function. Top-soil in a highly sort after aggregate in gardens for preparing lawn turfs and replenishing damaged or eroded areas of the garden bed as well as for laying fresh garden beds; water retention and nutrition imparting properties are the two most important reasons behind its position as an irreplaceable component in any thriving garden.

Ballast and Type 1 stones from the Ministry of Transport (MOT)

Ballast owing to their sharp texture as a result of extractions from stone crushing are consistently appropriated into concrete mixes becoming instrumental as layer above saturated grade in pathways and pavements. Their usage in extensive in blinding concrete layers as well as party to the infill materials in the hardcore layer within the external walls of a structure. Finer ballasts are usually deployed as sub-base material in foundation work receiving concrete layers while those acting as backfill material or under railway sleepers are bigger in dimensions. Type 1 inert materials consisting of various stones such as granites, limestone, and grit sand are approved by the Ministry of Transport (MOT) for reliable use in sub-base layers of driveways, pavements and as backfill material for trenches as well as trench fill foundation work.
