Effect of Solids-To-Liquids, Na2SiO3-To-NaOH and Curing Temperature on the Palm Oil Boiler Ash (Si + Ca) Geopolymerisation System

Zarina, Yahya; Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin; Khairul Nizar, Ismail; Rafiza, Abd Razak; Sandu, Andrei Victor (MDPI AG, 2015)

This paper investigates the effect of the solids-to-liquids (S/L) and Na2SiO3/NaOH ratios on the production of palm oil boiler ash (POBA) based geopolymer. Sodium silicate and sodium hydroxide (NaOH) solution were used as ...

Optimization of NaOH Molarity, LUSI Mud/Alkaline Activator, and Na2SiO3/NaOH Ratio to Produce Lightweight Aggregate-Based Geopolymer

Rafiza, Abdul Razak; Mohd Mustafa Al Bakri, Abdullah; Kamarudin, Hussin; Khairul Nizar, Ismail; Djwantoro, Hardjito; Zarina, Yahya (MDPI AG, 2015-05-21)

This paper presents the mechanical function and characterization of an artificial lightweight geopolymer aggregate (ALGA) using LUSI (Sidoarjo mud) and alkaline activator as source materials. LUSI stands for LU-Lumpur and ...
