Review on fly ash-based geopolymer concrete without portland cement
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper summarizes the factors that affect the properties of fly ash-based geopolymer concrete. Alkaline activator is an important material that controls the properties of geopolymer concrete. The workability of fresh ...
Influence of activator composition on the properties of calcined kaolin geopolymeric powder
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper studied the influence of activator composition on the properties of calcined kaolin geopolymeric powder. The alkaline activation of calcined kaolin was performed in mixture of waterglass liquid and NaOH solution ...
Effects of fly ash addition on compressive strength and flexural strength of foamed cement composites
(Trans Tech Publications, 2013)
In this study, the mixing of polystyrene (PS) beads and fly ash as a sand replacement material in foamed cement composites (FCC) has been investigated. Specifically, the mechanical properties such as compressive strength ...
Physical & Chemical properties of Pulverised Fuel Ash
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
Pulverised fuel ash is the finely divided mineral residue resulting from the combustion of coal in electric generating plants. Pulverised fuel ash consists of inorganic, incombustible matter present in the coal that has ...
