Article: STRENGTH CHARACTERISTIC OF GEOPOLYMER CONCRETE CONTAINING RECYCLED CONCRETE AGGREGATE
[show abstract] [hide abstract]
ABSTRACT: Abstract--- Malaysian is one of the develop countries that need to face environmental pollution. Have many ways to reduce environmental pollution that causes by production of Portland cement and cause by the increasing of waste material. Geopolymer concrete incorporating with recycle concrete aggregate (RCA) is one of the method. Waste Paper Sludge Ash (WPSA) and alkaline liquid as a binder are being used to replaced the Portland cement to produce geopolymer concrete. The alkaline liquid that been used in geopolymerisation is the combination of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). In the present study, two (2) series of geopolymer concrete specimens composing two (2) different molar of sodium hydroxide (NaOH) which are 8M and 14M were adopted. There are 30 cube specimens at size 100mm x 100mm x 100mm were prepared which is 15 cubes for 8M and another 15 cubes for 14M. The compressive strength of the geopolymer concrete specimens is tested at the age of 3, 7, 14, 21 and 28 days after cured in local laboratory ambient condition. The result shows that the strength of geopolymer concrete based Waste Paper Sludge Ash (WPSA) incorporating with recycle concrete aggregate (RCA) increase by increasing the molarities of sodium hydroxide (NaOH).International Journal of Civil & Environmental Engineering IJCEE-IJENS Vol: 11 No: 01. 01/2011; 11.
