For this purpose, 99 concrete mixes were designed and applied. SF and PPF were used at six-volume replacement contents of 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5%. Moreover, nano-silica (NS) was used at three contents, 0%, 1% and 2%, and silica fume powder (SP) was also used at three weight ratios (0%, 5% and 10%). The slump, compressive and tensile strength, elasticity modulus, water absorption and the electric resistivity of concrete specimens were examined. The results showed that using 1% NS and 10% SP together with 0.5% PPF improved the compressive strength of HSC by about 123%; however, the effect of SF on tensile strength is more significant and adding 0.5% SF with both 2% NS and 10% SP increased the tensile strength by 104%. Moreover, increasing the SF content reduces the electric resistivity while using PPF improves this property especially when 1% NS was employed, and it was enhanced by about 68% when 0.5% SF and 1% NS were utilized with 10% SP.<\/jats:p>","DOI":"10.3390\/app11209696","type":"journal-article","created":{"date-parts":[[2021,10,18]],"date-time":"2021-10-18T16:43:55Z","timestamp":1634575435000},"page":"9696","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Properties of Fibre-Reinforced High-Strength Concrete with Nano-Silica and Silica Fume"],"prefix":"10.3390","volume":"11","author":[{"given":"Arash","family":"Karimipour","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, University of Texas at El Paso and the Member of Centre for Transportation Infrastructure System, El Paso, TX 79968, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1667-7812","authenticated-orcid":false,"given":"Mansour","family":"Ghalehnovi","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Ferdowsi University of Mashhad, Mashhad 91779-48974, Iran"}]},{"given":"Mahmoud","family":"Edalati","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Ilam University, Ilam 69311-69991, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6766-2736","authenticated-orcid":false,"given":"Jorge","family":"de Brito","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georresources, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1649-004 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1016\/j.jclepro.2015.01.053","article-title":"Sustainable use of marble slurry in concrete","volume":"94","author":"Rana","year":"2015","journal-title":"J.
