Al 3+ - Ca2+ INTERACTION IN PLANTS GROWING IN ACID SOILS: AL-PHYTOTOXICITY RESPONSE TO CALCAREOUS AMENDMENTS (2010, unknown): “Phosphogypsum PG is a primary by-product of phosphoric acid in the fertilizer industry (Kumar, 2002).”
Utilization of solid wastes in construction materials (2010, methodology): “A large volume of purified PG can be used by combining with fly ash and lime to produce construction materials such as bricks and blocks (Yang et al., 2009; Kumar, 2002; Kumar, 2003).”
Physico-mechanical and thermal performances of newly developed rubber-added bricks (2008, background): “Conventional type of brick is made from burnt clay and a significant quantity of fuel is consumed during its production [17].”
Stabilisation of black cotton soil for subgrade application using fly ash geopolymer (2018, background): “This is due to the reason that fly ash is considered as a waste material unlike cement and lime and the global FA production from thermal power plants accounts for about 1 billion tons per annum (Kumar, 2002; Pandian, 2004).”
Utilization of recycled concrete fines and powders to produce alkali-activated slag concrete blocks (2020, background): “Kumar (2002) investigated the feasibility of producing hollow blocks by using class F fly ash, calcined phosphogypsum and mineral lime, and reported that the produced hollow blocks had sufficient strength for the application in low-cost housing development.”
