This paper reported the properties of kaolin geopolymers in term of the bulk density, compressive strength, qualitative observation and SEM analysis of the kaolin geopolymers. Kaolin geopolymers were synthesized through ...

This paper presents the development of a nano geopolymer for sustainable concrete using fly ash synthesized by high-energy ball milling. In this paper, we report on our investigation of the effects of grinding on the binder ...

Properties of oil palm trunk fiber reinforced cement composite were investigated in this study. Oil palm trunk fiber was used to improve the properties of cement composite. It was found that increasing in oil palm trunk ...

Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ...

The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ...

The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ...

This study presents the compressive strength and crack propagation of cement composites reinforced coconut fibre. The development of cement composites in this research were done by substituting coconut fibre to the portion ...

Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...

This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to ...

Fly ash and a mixture of alkaline activators namely sodium silicate (Waterglass) and sodium hydroxide (NaOH) solution were used for preparing geopolymer. The aim of this research is to determine the optimum value of the ...
