Report of RILEM TC 281-CCC: outcomes of a round robin on the resistance to accelerated carbonation of Portland, Portland-fly ash and blast-furnace blended cements
(2022-04)
Article
Accés restringit per política de l'editorialMany (inter)national standards exist to evaluate the resistance of mortar and concrete to carbonation. When a carbonation coefficient is used for performance comparison of mixtures or service life prediction, the applied ... -
Residue strength, water absorption and pore size distributions of recycled aggregate concrete after exposure to elevated temperatures
(2014-10)
Article
Accés restringit per política de l'editorialIn this paper, the effects of high temperature exposure of recycled aggregate concretes in terms of residual strengths, capillary water absorption capacity and pore size distribution are discussed. Two mineral admixtures, ... -
Steam curing influence on fly ash high-performance recycled concrete
(2016-11)
Article
Accés restringit per política de l'editorialHigh-performance concrete (HPC) mixtures were produced using 100% coarse recycled concrete aggregates (RCAs) from three different qualities. The concretes were produced using two binders: portland cement and portland cement ... -
Synthesis of hydrous iron oxide/aluminum hydroxide composite loaded on coal fly ash as an effective mesoporous and low-cost sorbent for Cr(VI) sorption: Fuzzy logic modeling
(2017-04-01)
Article
Accés obertThe aim of this research was to estimate the possibility of using synthesized hydrous iron oxide/aluminium hydroxide composite loaded on coal fly ash (FA3) as an efficient sorbent for Cr(VI) sorption from aqueous solution. ... -
Synthesis of zeolites from coal fly ash: an overview
(2002-05-02)
Article
Accés restringit per política de l'editorialCoal combustion by-products production in USA and EU is estimated in around 115 million tons per year. A large portion of this production is accounted for the coal fly ash (CFA). Cement and concrete manufacturing consumes ... -
Temperature for geopolymerization of fly ash. Mechanical behaviour
(Institute of Research Engineers and Doctors (the IRED), 2015-04-30)
Article
Accés obertAlkali activation of fly ash (FA) is a chemical process which allows the transformation of the amorphous structure which makes up most of its particles, in compact cementitious skeletons geopolymers are called solid ... -
Up to 100% replacement of natural materials from residues: recycling blast furnace slag and fly ash as self-leveling cementitious building materials
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-05)
Article
Accés obertThe objective of this research is to study the use in the construction industry of recycled slag (SL) and fly ash (FA) using from 0.1 to 5% calcium sulfate (wCS¯). These wastes have been used to make ternary mixture systems ...
