Advanced Science, EarlyView.The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using

Experimental and Numerical Investigation of the Fracture Behavior of Particle Reinforced Alkali Activated Slag Mortars [PDF]
Journal of Materials in Civil Engineering, 2019, 2019 This paper presents fracture response of alkali-activated slag (AAS) mortars with up to 30% (by volume) of slag being replaced by waste iron powder which contains a significant fraction of elongated particles. The elongated iron particles act as micro-reinforcement and improve the crack resistance of AAS mortars by increasing the area of fracture ...

Chemistry – A European Journal, Accepted Article.Polycarboxylate ether (PCE) and polyphosphate ether (PPE) dispersants (known as superplasticizers) are indispensable components of modern concrete mix designs. PCEs and PPEs cause retardation of the cement hydration as a secondary effect which causes delayed concrete strength development.

Microconcrete with partial replacement of Portland cement by fly ash and hydrated lime addition [PDF]
, 2014 [EN] The reduction in Portland cement consumption means lower CO2 emissions. Partial replacement of Portland cement by pozzolans sucha as fly ash has its limitations due to the quantity of calcium hydroxide generated in the mix.
