fly ash, also known as flue-ash is a residue which is generated during combustion and consists of fine particles. there are impurities in coal which mostly consist of clays, limestone and dolomite particles. these turn up into ash as they cannot be completely burned.
fly ash is useful in a number of ways and is one of the most researched upon mineral source. it is mainly a pozzolanic substance which contains aluminum and silicon material which in return due to the presence of water can take form of cement.
a lot of research and development initiative have been taken place across the globe to build and develop technologies that can utilize the full potential of fly ash. royal mineral takes care to ensure flawless production stages.

• the process requires fly ash that consists of impurities to be mixed in suitable proportion with either lime or gypsum. then these are added to form a uniform mixture. even cement can be used instead of lime and gypsum. water is added into the mixture and after it is dried, the mixture is transferred into a molding furnace.
• here either the working takes place hydraulically or compacted through pressure. now what concludes is the required fly ash being turned into concrete and used in other applications. in addition, there are times when lime might not be available as it could be that its cost is way too high, therefore cement acts as a fine alternative and used instead of it. in addition, it is easily available and costs way too low as compared to lime.

Ground-granulated blast-furnace slag (GGBFS or GGBS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
The main components of blast furnace slag are CaO, SiO2, Al2O3 and MgO.
GGBFS is used to make durable concrete structures in combination with ordinary portland cement and/or other pozzolanic materials.Use of GGBFS significantly reduces the risk of damages caused by alkalisilica reaction (ASR), provides higher resistance to chloride ingress reducing the risk of reinforcement corrosion and provides higher resistance to attacks by sulfate and other chemicals.

Granulated Blast Furnace Slag or GBFS is formed when Blast Furnace Slag or BFS is successively at a fast rate quenched from the furnace rather than left for cooling. It has a density of about 60% to 70% that of natural sand. This material has a much increased resistance to sulfate attack. This eventually leads to better performance in countering acids of any type. In GBFS, no type of reaction related to alkali and silica occurs. Also the material provides a huge saving in connection to carbon dioxide emission which is an extra boon. What constitutes GBFS are its properties that consist of durability, appearance, higher ultimate strength than concrete which is made up of Portland cement and high sustainability level of the product made out of this material.

• The composition of the slag varies as per the impurities that are present and also on the composition of the raw materials through which the product has to be extracted. So first of all, the molten Blast furnace slag or BFS is separated from molten iron. Then the slag is made to run into or transported to ground area for air-cooling purposes.
• Here it solidifies and converts into a rock. The rock is called crystalline Blast furnace slag. Now the quenching of molded slag is done rapidly by passing it through high pressure trough and then consequently into high pressure sprays of water.
• This procedure eventually causes the molten slag to overheat and this leads into its explosion. This explosion that occurs forms what we know as Granulated Blast Furnace Slag or GBFS. This is then stocked in piles where it is dewatered and collected with conventional front-end loaders.

Baryte is generally white or colorless, and is the main source of barium. Barite is found in the southern parts of India. It is extracted by both surface and underground mining.
It is non-toxic and physically and chemically non-reactive. It is available in hydrous form as well as lumps.

Garnet is pure and natural sand. Of the six major varieties of Garnet (Almandine, Andradite, Grossularite, Pyrope, Spessartite, Uvarovite), Almandine is the best abrasive Garnet with the composition of 3FeO, AI203, ESIO2. As Garnet has low content of free silica in it, it is widely used in sand blasting and waterjet cutting.

Micro Silica also known as Silica fume. It is a by product of producing silicon metal or ferrosilicon alloys in smelter using electric arc furnaces. It is a grey coloured powder, pozzolanic in nature.

Magnesium silicate has a trade name of Talc. It possesses lubricating properties, high luster and sheen. The colour of the material varies from the pure white to silvery white. It is one of the softest mineral and has a soapy feel.

Calcination is a process of heating, hence calcined bauxite is obtained by heating the high grade ore of the bauxite. Heating further removes the moisture content from the ore and thus results in the increase of the alumina content.

Bauxite, an aluminium ore, is the worlds main source of aluminium. It consists mostly of the minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite.

Metakaolin is form of calcined or dehydroxilated china clay. During calcination morphological, mineralogical and chemical changes occur which result in products with excellent optical properties.
