Enhancement of strength and durability of fly ash concrete in seawater environments: Synergistic effect of nanoparticles
Sudha Uthaman,Vinita Vishwakarma,Rani P. George,D. Ramachandran,Kalpana Kumari,R. Preetha,M. Premila,R. Rajaraman,U. Kamachi Mudali,G. Amarendra +9 more
TL;DR: In this article, the nano-titania and nano-calcium carbonate at 2% by weight of cement were added to fly ash concrete to increase the pozzolanic activity resulting in faster hydration, early-age strength and long-term compressive and split tensile strength.
Journal ArticleDOI
Enhanced seawater corrosion resistance of reinforcement in nanophase modified fly ash concrete
TL;DR: In this article, a method for enhancing the corrosion resistance of reinforcements through nanophase modification of fly ash concrete is presented, which can prevent diffusion and movement of chloride ions to surface of the rebar and thereby maintain the passivity of the thin iron oxide layer around the steel rebar.
Book ChapterDOI
Environmental impact of sustainable green concrete
Vinita Vishwakarma,Sudha Uthaman +1 more
TL;DR: In this paper, the importance of manufacturing green concrete using recycled waste materials and nanoparticles with its advantage and scope is discussed in detail, where the authors also discuss the potential of green concrete mix for commercialization by providing developers and contractors with an alternative concrete.
Journal ArticleDOI
Studies of carbonation process in nanoparticles modified fly ash concrete
TL;DR: The major cause of concrete corrosion is carbonation where atmospheric carbon dioxide (CO2) penetrates the concrete structure and deteriorates it as discussed by the authors, which is a major cause for concrete corrosion.
Journal ArticleDOI
Investigation on surface sulfate attack of nanoparticle-modified fly ash concrete
TL;DR: The enhanced properties of fly ash concrete against sulfate attack could be achieved with less C3A content thus reducing the available Ca(OH)2 and reducing the possibility of development of deleterious ettringite and gypsum.
