Abstract Coupled Thermal-Hydraulic-Mechanical-Chemical (THMC) approaches may be important for assessing the long-term durability of cementitious materials. We present a multiphysics approach to overcome past limitations THMC modelling and validate it based on experimental results accelerated carbonation tests. Our numerical rests sequential coupling between Hytec Cast3m. computes evolution hydr...

This research has investigated the structural changes and pozzolanic activity produced in acid activated smectite clay. The activation treatment used HCl at different concentrations, using times a range of temperatures. X-ray diffraction, Fourier transform infrared spectroscopy scanning electron microscopy coupled with energy dispersive were to determine dissolution mechanism characterise clay ...

The phosphogypsum is a by-product of the phosphate fertilizer industry. It has accumulated over several decades, and not only takes up large amount land, but also poses significant risk to environment resource waste. In order promote use phosphogypsum, its hydration hardening characteristics are studied using scanning electron microscope, X-ray diffractometer mercury intrusion porosimeter. When...

The rapid urbanization and industrialization of a country tends to generate large volume industrial waste in the environment. In this sustainability era, feasibility recycling has gained attention by researchers industry practitioners. Silicomanganese (SiMn) slag is common produced ferro-alloy smelting plant Sarawak. This paper intends present review on SiMn into more sustainable construction m...

ID No:180 ABSTRACT In this paper aims a thorough characterization will be performed of the effects of crystalline admixtures, currently employed as porosity reducing admixtures, on the self-healing capacity of the cementitious composites, i.e. their capacity to completely or partially re-seal cracks and, in case, also exhibit recovery of mechanical properties.In this paper aims a thorough chara...

Autonomous crack healing of cementitious composite, a construction material that is susceptible to cracking, is of great significance to improve the serviceability and to prolong the longevity of concrete structures. In this study, the St-DVB microcapsules enclosing epoxy resins as the adhesive agent were embedded in cement paste to achieve self-healing capability. The self-healing efficiency w...
