Buff-coloured, dolomite aggregates produced from very high purity Carboniferous Dolomite.
The Golconda range of dolomite aggregates are produced from very high purity Carboniferous Dolomite at the company's Ryder Point quarry and processing operations in Derbyshire. The material has been crushed and screened to produce products of exceptional purity and consistency available in a variety of sizes.
Granular Golconda products are used in agriculture as a quick acting liming material with a high neutralising value to counteract high soil acidity. It also provides an essential source of magnesium necessary for healthy plant growth.
Concrete is a composite construction material, compose of cement, aggregate (generally a coarse aggregate made from crushed rocks such as Golconda dolomite, plus a fine aggregate such as sand), water and chemical admixtures.
Golconda dolomite aggregates are used in variety of ways in construction projects including drainage & pitching, pipe bedding and foundation footings for new buildings or extensions.
Decorative Golconda dolomite aggregates, chippings and grits are used in landscaping projects such as cycling ways and footpaths, driveways and car parks as well as for ground cover in gardens and rockeries.
Golconda dolomite chippings can be used as a decorative, protective coating for felt flat roofs. Chippings provide a ‘loading’ weight preventing the felt being lifted by wind as well as protection from the sun which would otherwise degrade the felt.
The typical physical properties of Golconda Aggregates are as follows:
|Appearance||buff coloured aggregate|
|Calcium Oxide (%)||31.5|
|Magnesium Oxide (%)||20.5 min|
|Available Grades/Sizes||3mm – 75mm|
|Clean, evenly graded aggregates|
As the material is derived from a natural source its colour may vary. For further information please consult the relevant technical data sheet.
Golconda Aggregates are available in a wide range sizes ranging from 3mm to 75mm, including grades that comply with British Standard specifications BS EN 12620 (Aggregates for concrete) and BS EN 13242 (Aggregates for use in civil engineering work and road construction).
Our operations are fully accredited to ISO 9001 and ISO 14001. Datasheets and SDS on specific grades are available on request. Please contact us for further information.
Golconda Aggregates are supplied in bulk
Dolomite (CAS: 16389-88-1 & EINECS: 240-440-2) is exempt from the obligation to pre-register under the REACH legislation. The exemption is granted in Annex V, Paragraph 7 as the material is a naturally occurring mineral found in nature.
