Nonferrous waste foundry sand and milling fly ash as alternative low mechanical strength materials for construction industry: effect on mortars at early ages by Vázquez Rodríguez, Francisco Javier, Valadez Ramos, Jaime Elihezer, Puente Ornelas, Rodrigo, Contreras, J. E., Arato, A., Rodríguez Castellanos, Edén Amaral

“…The results indicate that the addition of milling fly ash in AWFS mortars increases the mechanical resistance, mostly at 5% mass reaching the maximum value of 10 MPa at 28 days of age. Microstructurally, it was found a porous cement matrix with some cracking caused by the reaction of portland cement with the metallic aluminum remaining in the waste sand, which is correlated to the low mechanical resistance obtained. …”
