The results indicate that, compared with plain cement matrix, the PP\/PE fibre-reinforced cement matrices (FRC) revealed improvements on their mechanical performance. Increases of 37 \u00b1 1% on compressive (40.2 MPa) and flexural strengths (8.1 MPa) were obtained for 24 mm fibre length composites containing a rather low fibre\u2019s content (1 wt.%). These mechanical improvements were achieved after optimisation of the mortar workability by the addition of a superplasticizer. FRC mechanical behaviours also evidenced that despite the compressive strengths increasing with fibre length, a flexural strength effect is only noticeable for a 24 mm length fibre-reinforced composite and for fibres volume higher than 2.9 %. Morphological observations showed a strong interaction between fibres and cement matrix, evidenced a crack arrest role (bridge effect) on fibre\/cement interfacial zone and revealed a typical multiple fracture cracking mechanism.<\/jats:p>","DOI":"10.4028\/www.scientific.net\/msf.730-732.343","type":"journal-article","created":{"date-parts":[[2012,11,12]],"date-time":"2012-11-12T11:00:38Z","timestamp":1352718038000},"page":"343-348","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid Fibre-Reinforced Cement Composite"],"prefix":"10.4028","volume":"730-732","author":[{"given":"Elisabete R.","family":"Silva","sequence":"first","affiliation":[{"name":"Instituto Superior T\u00e9cnico"}]},{"given":"Humberto E.","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Instituto Superior T\u00e9cnico"}]},{"given":"Jorge F.J.","family":"Coelho","sequence":"additional","affiliation":[{"name":"Universidade de Coimbra"}]},{"given":"Jo\u00e3o C.","family":"Bordado","sequence":"additional","affiliation":[{"name":"Instituto Superior T\u00e9cnico"}]}],"member":"2457","published-online":{"date-parts":[[2012,11,12]]},"reference":[{"key":"1772273","doi-asserted-by":"publisher","unstructured":"E.
