I hereby certify that this thesis entitled “Creep Behaviour of Geopolymer Concrete” contains no material which has been accepted for the award to the candidate of any other degree or diploma, except where due reference is made in the text of the examinable outcome To the best of my knowledge, the thesis contains no material
The chemistry of alkali-activated slag (AAS)-based cements is simulated using CNASH_ss and an ideal solid solution thermodynamic model for MgAl-OH-LDH that is also developed in the thesis This analysis provides a good description of Na2SiO3-activated slag cement chemistry and accurately predicts chemical shrinkage in this material
This study aimed to fully replace Portland cement (PC) with environmentally friendly binders capable of improving longevity of concrete The new binders consisted of different proportions of natural Pozzolan and slag which were alkaline-activated with various combinations of sodium hydroxide and sodium silicate A step-by-step research program was designed to (1) develop alkali-activated .

In this standard practice, the minimum level of slag is determined by consideration of aggregate reactivity, alkali availability, the exposure conditions, and the size and type of the concrete structure Slag cement contains a small amount of alkalisTypically, the amount of alkali is similar to that of low- to-moderate-alkali portland cement .
The set of alkali-activated slag cement (AASC) and concrete and the measures for set-retarding were reviewed Due to the fast set of high and super high strength alkali-activated slag cement and concrete, an inorganic compound set retarder YP-3 was developed The effect of the retarder on setting time and strength as well as heat evolution of AASC were tested, and the mechanism of the retarder .
