Formulation of geopolymer binders for 3D concrete printing (2025)
Presentation / Conference Contribution

This study develops 3D-printable metakaolin geopolymer pastes activated solely with NaOH (6–16 M), eliminating sodium silicate to prevent its detrimental reduction of open time, which is critical for extrusion. NaOH concentration directly governs rea... Read More about Formulation of geopolymer binders for 3D concrete printing.

Exploring balanced modal split for freight transportation system: A case of the central region of South Africa (2025)
Journal Article

Ensuring sustainability in transportation systems demands a harmonious distribution of freight. In the regional context of South Africa, road and rail transportation play pivotal roles, yet a significant imbalance exists, posing sustainability challe...

Single-parameter concrete carbonation model for varying environmental exposure conditions (2024)
Journal Article

Carbonation-induced reinforced steel concrete corrosion is a prominent concern related to engineering design and maintenance. The Durability Index (DI) approach was developed in South Africa to address this concern and enhance the durability performa...

Influence of drying rate on carbonation of concrete with supplementary cementitious materials (2024)
Presentation / Conference Contribution

The relative humidity (RH) in concrete pores has a major influence on the rate of carbonation of concrete.
Since carbonation is a reaction-diffusion process, the favourable moisture condition for carbonation is in
the range of 50-70% RH. At higher... Read More about Influence of drying rate on carbonation of concrete with supplementary cementitious materials.
