Cement paste was firstly made by alkaline activation of calcined kaolin with alkali activator (mixture of 6-10 M NaOH and Na 2SiO 3 solution), heated in oven at temperature of 80°C forming a solidified product, followed by pulverization to fixed particle size powder. The parameters involved in this processing route (alkali concentration, calcined kaolin to activator ratio, alkali activator ratio and heating conditions) were investigated. For compressive testing, cement powder was added with water and then cured to produce cubes. Compressive strength, microstructure, XRD and FTIR analysis were studied. Result showed that the processing route has the potential to produce cement powder where SEM micrographs have proved that the geopolymerization process continued after addition of water forming a homogeneous structure and geopolymers bonding increased in intensity which was observed through IR analysis. It was believed that presences of crystalline phase as seen in XRD diffractogram were good for mechanical properties. 2013-02-06T08:31:50Z 2013-02-06T08:31:50Z 2012-05 Article Construction and Building Materials, vol. 30, 2012, pages 794–802 0950-0618 http://www.sciencedirect.com/science/article/pii/S0950061811007690 http://hdl.handle.net/123456789/23399 en Elsevier Ltd |
