NOVELTY - Composition of a graphene oxide geopolymer mortar formed by mixing palm oil fuel ash (POFA) and sand (weight ratio of 1:2) with sodium hydroxide solution and sodium silicate solution (weight ratio of 1:2.5) and adding 5 mg/ml of 0.2-0.6% solution of graphene oxide is claimed. USE - The composition of a graphene oxide geopolymer mortar is useful in grapheme oxide geopolymer mortar product. ADVANTAGE - The composition of a graphene oxide geopolymer mortar provides the product that exhibits maximum compressive strength of 13.3 (MPa) (n increase of 97% compressive strength as compared to mortar without grapheme oxide) which is shown by mortar made with the addition of 0.6% grapheme oxide and 14 M sodium hydroxide. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) use of POFA can also be replaced with fly ash from other sources e.g. coal fly ash or fly ash from other sources or from other raw materials containing silica and alumina e.g. kaolin and others; and (2) use of sodium hydroxide activators can also be replaced with potassium hydroxide from various sources of raw materials.
