Plaster M-Sand

IS:1542:1992

Plaster Sand is is a very fine grade of sand used for internal and external render, plastering and screeding. It creates a smooth and even finish and can be used for filling cracks. The Fineness Modulus of this sand is not less than 1.4.

Concrete M-Sand

IS:383:2016

Concrete Sand is coarse in nature and primarily used in the manufacture of ready mix concrete and asphalt. The Fineness Modulus of this sand is between 2.3 to 3.2. It is graded and washed adequately to remove unwanted silt for optimum mix-design.

Masonry M-Sand

IS:2116:1980

Masonry or Mortar Sand is a fine graded all purpose sand that can be used as a fill material, paver base and levelling agent. Its ultra fine texture and ease of use helps in projects where style and design are important. Fineness Modulus of this sand is between 1.15 to 2.95

Recycled M-Sand

IS:383:2016

Recycled sands are an environmentally friendly, cost effective alternative to natural sand. Produced from construction & demolition waste, recycled sands can be used for Mortar, concrete road construction, paver blocks and other street furnitures.

Silica Sand - Glass

IS:488:1980

Silica sand is the primary component to produce flat glass for building and automotive use, container glass for foods, beverages and tableware. It provides the essential SiO2 component of glass formulation, and its chemical purity is the primary determinant of colour, clarity, and strength.

Silica Sand - Foundry

IS:3018:1977

Silica sand is an essential part of the ferrous and non-ferrous foundry industry. Silica’s high fusion point (1760°C) and low rate of thermal expansion produce stable cores and molds compatible with all pouring temperatures and alloy systems.

CRF (Crushed Rock Fines)

CRF is a by-product of the quarrying industry and results from rock-crushing operation as waste, most of which passes through 6mm IS sieve. In the industry it is also known as quarry dust, stone dust or crusher dust.
As per MORTH, quarry dust may be used in bituminous base course in construction of roads and highways. Landscapers use crusher dust for filling holes, as bedding for paving stones and more recently its applications have broadened to other areas.

Crushed Stone Sand

IS 383:2016

Crushed stone sand is produced by crushing hard stones to less than 4.75mm particles by using roller crushers or vertical shaft impactors (VSI). Crushed stone sand has better particle shape and contains lower level of silt content when compared to CRF/crusher dust.
In the construction industry crushed stone sand is used in mortars for brick laying and in concrete applications by suitably altering the mix-design.

Aggregates

10 mm coarse aggregate

IS 383:2016

Aggregates are inert granular materials such as sand that, along with water and portland cement, are an essential ingredient in concrete.
10 mm Aggregates are mainly used in ready mix concrete, asphalt/bitumen/concrete roads base and sub-base course, pavements, separately or mixed with other aggregates depending on the application.

20 mm coarse aggregate

IS 383:2016

Aggregates are inert granular materials such as sand that, along with water and portland cement, are an essential ingredient in concrete.
20 mm Aggregates are mainly used in ready mix concrete, asphalt/bitumen/concrete roads base and sub-base course, pavements, separately or mixed with other aggregates depending on the application.

Granular Sub Base (GSB)

MORTH Table 400-1

Granular Sub Base (GSB) is natural or crushed material, used for road construction as a sub-base layer. Granular Sub Base is a layer in road foundation just above the compacted sub-grade layer.
GSB or granular sub-base prevents capillary water from rising; its particle size is so designed that the capillary action stops and does not go beyond GSB layer. Secondly, it works like a drainage layer where water can pass without damaging other road layers. It is made from crushed stone aggregate or river bed material free from organic constituents. It conforms to Table 400-1 of MORTH specification, with the percentage passing 0.075mm size restricted to 5%.

Silt

Silt is the by-product of manufactured sand and separated during washing process. Typical silt consists of granular particles sized less than 0.075 mm.
Good quality silt can be used in landscaping, as part of the mineral filler portion in hot mix asphalt paving mixtures or making cellular light-weight concrete (CLC) products as a replacement of fine aggregates in certain percentages.
