Lightweight Aggregates: A new energy and load saving building material
Light weight aggregates
“Ei-cobond” reactivated “Ceram cite” is a reinforced lightweight aggregate for concrete / mortar mix. It has been observed as natural raw material for conventional aggregates used are granules in form of aggregates are stone chips, pumiced, vermiculite, expandable clay and slate are considered to be extremely hazardous. All these materials these are coming from the mining / quires and there exerts causes serous effects on environment and human health.
Considering the increased concern about the environmental impact, Roy Research & Technology has developed a new environmental hazard free technology to reduce solid waste form the mining of raw materials and maximized use solid waste e.g. fly ash, coal gangue, silica bituminous pitch etc.
“Ei-cobond” activated and whiskered “Ceram cite” – a typical eco-friendly high value representation of modified lightweight aggregates with excellent adherent properties with concrete mix.
This has got great potential for development of new eco-friendly green material in field of wall panel road construction, building construction, earthquake proof building construction specially at the high altitude area including ballast for the railway track.
This concept not only saves building energy and cost saving. “Ei-cobond” activated “Ceram cite” prepare from fly ash, silica, coal gangue, sludge, mill scale, mineral ore dust and other sold waste were investigated through Roy Research and Technology’s R & D facility. It has been observed that our innovative light weight aggregate obtained the crushing strength within 4.0 – 13.5 mpa and water absorption 2% – 10% and this are very much consistent with standard target. In other “Ceram cite” aggregate project the most important aspect is difficult in respect of preparation and application.
Through our unique innovative technology the mass production of lightweight aggregate in different shape with good adhesion property can be easily prepared and applied. This novel technology used in solid waste preparation as aggregate will open a new space for resource utilization.
This will have definitely much better impact to social environment and economic benefit including health hazard issue. As for example, stone grit aggregate from the stone queries during the time of mining creates stone fumes which is extremely health hazard. Workers in the queries faced on exposed in stone dust fumes. In result, silica can cause silicosis as well as sufficient long time expose leads to TB and pneumoconiosis besides probable radiation effect*.
This entire innovative technology will have great impact for removal of environmental related hazard.
“Eicobond” reactivated solid waste in form of “Ceram cite” light weight aggregate can provide a new space as affective and environmental resource utilization and overall economic benefit towards green construction.
Status of “Ceram cite” obtained from solid waste in India
In recent decade, the rapid development of lightweight building material is yet to start in India. However large numbers of industries are engaged in making of lightweight precast concrete wall panel system. This novel technology used in solid waste as aggregate will open a new space as a unique resource for lightweight building material. The common practice in construction industries to use aggregates for reinforced the structure. These aggregates come from the source of stone, pumiced, vermiculite, expandable clay, and slate.
Roy Research & Technology’s innovative work for light weight aggregate utilizing solid waste like fly ash will meet the demand for light weight structure. This technology will open up a new door for wide application such as fly ash and other solid waste of solid waste as “Ceram cite”. Through our experiment and testing we have found the strength to weight ratio of this new product is much better than your conventional aggregate in building industry.
