A green concrete composition comprising: a binder component comprising Portland cement (C), volcanic ash (VA), metakaolin (MK), and colloidal nano-silica (CNS); an aggregate component comprising fine aggregates (FA) and coarse aggregates (CA); water (W); and a super plasticizer.

Green concrete kit composed of four components

A mortar composition, which includes (i) a treated palm oil fuel ash, wherein the treated palm oil fuel ash is the only binder present, (ii) a fine aggregate, (iii) an alkali activator containing an aqueous solution of sodium hydroxide and sodium silicate, and (iv) aluminum hydroxide as a strength enhancer. A cured mortar made from the mortar composition is also disclosed with advantageous compressive strength properties.

Mortar composition containing iron oxide

Aluminum hydroxide enhanced mortar composition

A green concrete and mortar compositions free of Portland cement are disclosed. The compositions comprise Natural pozzolan, nanosilica particles, and alkaline activator. The green concrete produced from the composition of the invention is cured at ambient temperature and has higher compressive strength than that of concrete made with Portland cement.

Two component green concrete kit

Tinted mortar composition containing fuel ash

A concrete composition that includes (i) a treated palm oil fuel ash, wherein the treated palm oil fuel ash is the only binder present, (ii) a fine aggregate, (iii) a coarse aggregate, and (iv) an alkali activator containing an aqueous solution of sodium hydroxide and sodium silicate. A cured concrete made from the concrete composition is also disclosed with advantageous compressive strength properties.
