The optimization of the amount of cement in concrete can be achieved either by partially replacing it by additions or by reducing the binder content. The present work aims at optimizing the properties of concrete used in the production of reinforced concrete poles for electrical distribution lines, combining the maximization of compactness with the partial replacement of cement by fly ash, natural pozzolans, and electric furnace slags. Natural aggregates were also partially replaced by recycled ones in mixtures with fly ash. Two types of concrete were studied: a fresh molded one with a dry consistency and a formwork molded one with a plastic consistency. The following properties were characterized: mechanical properties (flexural, tensile splitting, and compressive strengths, as well as Young\u2019s modulus) and durability properties (capillary water absorption, water penetration depth under pressure, resistance to carbonation, chloride migration, and concrete surface resistivity). The service life of structures was estimated, taking the deterioration of reinforcement induced by concrete carbonation or chloride attack into account. Results revealed that mixtures with fly ash exhibit higher mechanical performance and mixtures with fly ash or pozzolans reveal much higher durability results than the full Portland cement-based mixtures.<\/jats:p>","DOI":"10.3390\/ma14154173","type":"journal-article","created":{"date-parts":[[2021,7,27]],"date-time":"2021-07-27T12:18:31Z","timestamp":1627388311000},"page":"4173","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Influence of Pozzolan, Slag and Recycled Aggregates on the Mechanical and Durability Properties of Low Cement Concrete"],"prefix":"10.3390","volume":"14","author":[{"given":"Eliana","family":"Soldado","sequence":"first","affiliation":[{"name":"ISEC-Polytechnic Institute of Coimbra, 3045-093 Coimbra, Portugal"}]},{"given":"Ana","family":"Antunes","sequence":"additional","affiliation":[{"name":"ISEC-Polytechnic Institute of Coimbra, 3045-093 Coimbra, Portugal"},{"name":"Civil Engineering Research and Innovation for Sustainability (CERIS), 1049-001 Lisbon, Portugal"}]},{"given":"Hugo","family":"Costa","sequence":"additional","affiliation":[{"name":"ISEC-Polytechnic Institute of Coimbra, 3045-093 Coimbra, Portugal"},{"name":"Civil Engineering Research and Innovation for Sustainability (CERIS), 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3254-2221","authenticated-orcid":false,"given":"Ricardo","family":"do Carmo","sequence":"additional","affiliation":[{"name":"ISEC-Polytechnic Institute of Coimbra, 3045-093 Coimbra, Portugal"},{"name":"Civil Engineering Research and Innovation for Sustainability (CERIS), 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1690-9887","authenticated-orcid":false,"given":"Eduardo","family":"J\u00falio","sequence":"additional","affiliation":[{"name":"Civil Engineering Research and Innovation for Sustainability (CERIS), 1049-001 Lisbon, Portugal"},{"name":"Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,27]]},"reference":[{"key":"ref_1","unstructured":"The European Cement Association (CEMBUREAU) (2021, June 23).
