* PHOSCAST Phoscast : Phosphate Bonded Castables * PURPOSE customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system. BACKGROUND * Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles. * GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion * Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected. APPLICATION Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.

The Ground Granulated Blast Furnace Slag (GGBS/GGBFS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementations material for building high durable concrete stricture in the world today! GGBS has taken over a top place of high-performance cement and concrete mineral additives with its unique characteristics of hydration, low-price raw material. GGBS is obtained by quenching molten iron blast furnace slag (a by-product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distribution. The main components of blast furnace slag are CaO (30-50%), SiO2 (28-38%), Al2O3 (8-24%), and MgO (1-18%). The other important aspect of GGBS is its superiority in concrete durability which extends the lifespan of buildings from fifty years to a hundred years.

Aggregates are mixtures of sand, gravel, crushed rock or other bulk minerals used in construction, principally as a component of concrete, and in civil engineering. At CEMENTATION we supply aggregates for a range of core applications, from fill materials to aggregates that can be used in concrete, precast concrete, asphalt and for surface dressing. Aggregate plays an important role in concrete and construction part. We supply quality material which makes durable concrete with higher compressive strength and low permeability having better finish. We can supply a wide range of coarse, fine and blended aggregates in accordance with international standards. We acquire rock mines and stone crushing plants and enable us to fulfil contract of any size. Progressive stages if crushing and screening enable us to produce a range of aggregate sizes (06mm to 65mm) APPLICATIONS Road and Highway surfaces Constructions or Civil work Railway Ballast To make Concrete or Asphalt Filling
Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth. They account for an estimated 60% of exposed rocks, as well as soils, clays, and other unconsolidated sediments, and are principal components in rock classification schemes. The minerals included in this group are the orthoclase, microcline and plagioclase feldspars. APPLICATIONS Glass making Ceramics Porcelain Electrodes Abrasion We at CEMENTATION produce Feldspar of minerals containing Potassium and Sodium. Our supply is available in Lumps, Granules and Powder form.
Quartz is the most abundant and most common mineral on the Earth. It is found in almost every geological environment and also it is at least a component of almost every rock type. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colours and forms. The most important distinction between the types of quartz is that one is of macro crystalline, which is individual crystal visible to the unaided eye, and the other is microcrystalline or cryptocrystalline varieties, aggregates of crystals visible only under high magnification. Chalcedony is the generic term for cryptocrystalline quartz. The transparent variety tends to be microcrystalline and the cryptocrystalline varieties are either translucent or mostly opaque.
Bauxite is a naturally occurring mineral comprising mainly of aluminium hydroxides (the trihydrate Gibbsite Al(OH)3and the AlOOH monohydrate polymorphs boehmite and diaspore), with other components in the mineral typically being silica, iron oxide, titania and aluminosilicates (clay etc). It’s a rock from Laterite soil and it is a primary Ore of Aluminium. Properties of Bauxite include low iron content; a high Polished Stone Value (PSV) for high friction surfacing applications; a high melting point and density. APPLICATIONS Gunning materials High friction surfacing Minerals for abrasion Refractory castables Mouldable and Ramming Mixes Refractory mineral blends CEMENTATION believes in supplying quality bauxite with consistency to its customers across the world, according to their needs.
