Coal Bottom Ash for Portland Cement Production

open access: yes, 2017
Because of industrialization growth, the amount of coal power plant wastes has increased very rapidly. Particularly, the disposal of coal bottom ash (CBA) is becoming an increasing concern for many countries because of the increasing volume generated ...

Mitigating Climate Change Through the Use of Cement Combinations in Concrete Construction [PDF]

open access: yes, 2017
Supplementary cementitious materials are by-products with lower embodied carbon-dioxide (eCO2) contents than Portland cement. But while supplementary cementitious materials could be used to mitigate climate change, their intrinsic hydraulicity and ...

Evaluating the high‐temperature resistance of self‐compacting mortar incorporating waste andesite powder as a mineral admixture

open access: yesStructural Concrete, EarlyView.
Abstract Significant amounts of waste material are generated at various stages of andesite stone processing, including mining, cutting, and polishing. Despite this, limited research has been conducted on the potential use of waste andesite powder (WAP) as a mineral admixture.

Assessment of corrosion attack morphology on reinforced concrete structures exposed to chlorides

open access: yesStructural Concrete, EarlyView.
Abstract Chloride‐induced corrosion of the reinforcement steel is the main degradation mechanism for reinforced concrete, considerably affecting the load and deformation capacity of structures. Despite its importance, there is limited knowledge about the morphology of corrosion attacks and accordingly, relatively crude assumptions are generally made ...

Application of low‐emission cement CEM II/C in concrete made with low‐effort processed recycled aggregates

open access: yesStructural Concrete, EarlyView.
Abstract The present study investigates the applicability of recycled concrete aggregates (RCA) for use in structural concrete made with low‐emission cement CEM II/C‐M (global warming potential of 377 kg CO2,eqv.). The aim is to show the potential of RCA processed with minimal energy, water, and economic expenditure.

Liquid-Solid Phase Transition Alloy as Reversible and Rapid Molding Bone Cement [PDF]

open access: yesarXiv, 2013
Bone cement has been demonstrated as an essential restorative material in the orthopedic surgery. However current materials often imply unavoidable drawbacks, such as tissue-cement reaction induced thermal injuries and troublesome revision procedure.
