  • Lime Putty Mortar with GGBS (Ground Granulated Blast Furnace Slag) (July '22) Ash Ahmed (July '22)

    Compressive and Flexural Strength of Non-Hydraulic Lime Mortar with Slag (GGBS)

    This paper investigates the properties of non-hydraulic (lime putty) lime mortar containing ground granulated blast-furnace slag (GGBS).

  • Lime Putty Mortar with Metakaolin Pozzolan Ash Ahmed (Feb '22)

    Compressive And Flexural Strength of Non-Hydraulic Lime Mortar with Metakaolin Pozzolan

    This paper investigates the properties of non-hydraulic (lime putty) lime mortar containing metakaolin (MK).

  • Limecrete with GGBS and Hydrated Lime Ash Ahmed (Oct '21)

    Potential Sustainable Cement Free Limecrete Based on GGBS & Hydrated Lime as an Alternative for Standardised Prescribed Concrete Applications

    A fundamental issue with the active ingredient of concrete, Portland cement, is its energy-intensive manufacturing process, which has led to the cement industry emitting up to 10% of global CO2 levels. To facilitate the reduction in the embodied CO2 of concrete, the Portland Cement (PC) content has been entirely replaced volumetrically with Hydrated Lime (HL) and ground granulated blast furnace slag (GGBS or SL).

  • Lime Mortar with PFA (Pulverised Fly Ash / Pulverised Fuel Ash) Ash Ahmed (Aug '20)

    Compressive and Flexural Strength of Non-Hydraulic Lime Mortar with PFA Pozzolan

    This paper investigates the properties of non-hydraulic (lime putty) lime mortar containing PFA (fly ash). Non-hydraulic lime mortars with PFA offer a more sustainable alternative to cement based mortars without compromising setting time or strength whilst offering improved flexibility and breathability.

  • Palm Oil Fuel Ash (POFA) Ash Ahmed (Nov '18)

    Palm Oil Fuel Ash as a Cement Replacement in Concrete

    This study investigates the effectiveness of agro waste ash by-product Palm Oil Fuel Ash (POFA) as a sustainable alternative to replace ordinary Portland cement (OPC).

  • Use of Coconut COIR in Fiber Reinforced Concrete, Soil and Lime Ash Ahmed (Dec '20)

    Coconut Fibre (COIR) as a Natural Alternative to Reinforcement Fibres in Concrete, Soil and Lime Mortars

    This paper examines the use of coconut COIR as a natural and sustainable alternative to reinforcement fibres in common use in the construction industry.
