influence of recycled aggregate replacement and fly ash content in performance of pervious concrete mixtures
Gabrieli Lazzari Vieira,Jéssica Zamboni Schiavon,Pietra Moraes Borges,Sérgio Roberto da Silva,Jairo José de Oliveira Andrade +4 more
TL;DR: In this paper, the use of recycled aggregates (RA) from construction and demolition waste and fly ash in pervious concrete was analyzed, and the results showed that the incorporation of 10% fly ash with 75% of recycled aggregate content showed an increase of 6% tendency to clogging compared to the reference concrete.
Journal ArticleDOI
Evaluation of tire rubber surface pre-treatment and silica fume on physical-mechanical behavior and microstructural properties of concrete
Cauana Melo Copetti,Pietra Moraes Borges,Jéssica Zamboni Squiavon,Sérgio Roberto da Silva,Jairo José de Oliveira Andrade +4 more
TL;DR: In this paper, the influence of a chemical pretreatment with NaOH on the physical, mechanical, microstructural properties of concretes with two rubber residue contents (15% and 30%) as a natural fine aggregate replacement, and the addition of silica fume (7.5% and 15%) to replace Portland cement.
Journal ArticleDOI
Mortars with recycled aggregate of construction and demolition waste: Mechanical properties and carbon uptake
Pietra Moraes Borges,Jéssica Zamboni Schiavon,Sérgio Roberto da Silva,Alex Neves Junior,Edna Possan,Jairo José de Oliveira Andrade +5 more
TL;DR: In this article , the substitution influence of natural aggregates (NA) for recycled aggregate (RA) in replacement levels of 0, 25, 50, 75, and 100% with three different particle size distributions was evaluated to evaluate the particle size influence.
