DESCRIPTION:As a new class of concrete\, the use of pervious concrete with
  the main application as pavement material\, is fast increasing due to a r
 ange of associated environmental benefits including reduce runoff\, enhanc
 ed storm water management\, reduce heat island effect\, retention of oil a
 nd other hydrocarbons\, recharge ground water level and reduce traffic noi
 se. However\, the production of Portland cement (PC)\, as the principal hy
 draulic cement in the concrete industry\, is one of the most energy-intens
 ive processes and is responsible for 5 to 8% of global annual anthropogeni
 c carbon dioxide (CO2) emission. Besides\, PC suffers from a number of dur
 ability drawbacks such as chemical attack and considerable thermal shrinka
 ge in mass concrete. The use of low carbon material and industrial by prod
 ucts as well as the development of new cement formulation have been most n
 oticed in last decade as the promising sustainability initiatives in cemen
 t industry and are the main subjects of this research. This study explored
  the feasibility of using reactive magnesia cements\, as a recent develope
 d sustainable alternative cement to PC\, in pervious concrete with a range
  of functional\, mechanical and environmental assessments. In addition\, t
 he feasibility of pervious concrete for immobilising a range of present he
 avy metals in stormwater runoff  (Zn\, Cu\, Pb\, Ni and Cd) was investigat
 ed as the function of mix composition\, pH\, flow rates and metals’ load
 ing.
