The use of iron blast furnace slag in various highway applications is economical and technically feasible however lingering doubts about its environmental impacts need to be investigated further. Steel Slag A by-product of the steel industry is formed when lime flux reacts with molten iron ore scrap metal or other ingredients charged into
Ductile iron pipe offers strength stiffness ductility and a range of sizes and thicknesses and is the typical choice for high-pressure and exposed piping. Plastic pipe is most widely used in short force mains and smaller diameters. Table 1 lists the types of pipe recommended for use in a force main system and suggested applications. Velocity
Carbon footprint reduction of paving materials could be explored through recycling mining by-products into different applications which will preserve natural resources and decrease environmental issues. One possible approach is to reuse quarry dust and mining ore waste as precursors in geopolymer applications. geopolymers are mineral polymers rich in aluminosilicates with an amorphous to a
List of BulkingSwell factors for various materials. The swell factor expressed in percentage is the amount of volume increase from bank volume undisturbed in place state to loose volume disturbed excavated state of the material due to voids air pockets added to the material after excavation
The need for cheaper and more economical soil improvement methods is of great significance in order to reduce the construction cost of flexible pavements. Also major problems caused by industrial waste in Nigeria can be minimised by recycling or re-using of such wastes for soil improvement. The application of cement and lime along for such purpose has proven to increase the construction cost
