Designing experiments based on factorial plans has shown to be a powerful tool for predicting and optimising advanced cement-based materials, such as self-compacting high-early-strength cement-based mortars. Nevertheless, the number of factor interactions required for factor scheduling increases considerably with the number of factors. Consequently, the probability that the interactions do not significantly affect the answer also increases. As such, fractioned factorial plans may be an exciting option. For the first time, the current work compares the regression models and the predicting capacity of full, fractionated (A and B fractions) and small factorial designs to describe self-compacting high-early-strength cement-based mortars\u2019 properties, namely, the funnel time, flexure and compressive strength at 24 h for the function of the mixture parameters Vw\/Vc, Sp\/p, Vw\/Vp, Vs\/Vm and Vfs\/Vs for the different factorial designs. We combine statistical methods and regression analysis. Response models were obtained from the full, fractionated, and small plans. The full and fractionated models seem appropriate for describing the properties of self-compacting high-early-strength cement-based mortars in the experimental region. Moreover, the predicting ability of the full and fractionated factorial designs is very similar; however, the small design predictions reveal some concerns. Our results confirm the potentiality of fractioned plans to reduce the number of experiments and consequently reduce the cost and time of experimentation when designing self-compacting high-early-strength cement-based mortars.<\/jats:p>","DOI":"10.3390\/app13148413","type":"journal-article","created":{"date-parts":[[2023,7,21]],"date-time":"2023-07-21T02:04:04Z","timestamp":1689905044000},"page":"8413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Modelling and Predicting Self-Compacting High Early Age Strength Mortars Properties: Comparison of Response Models from Full, Fractioned and Small Central Composite Designs"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3442-6224","authenticated-orcid":false,"given":"Nara","family":"Cangussu","sequence":"first","affiliation":[{"name":"CONSTRUCT-LABEST, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1646-4665","authenticated-orcid":false,"given":"Ana Mafalda","family":"Matos","sequence":"additional","affiliation":[{"name":"CONSTRUCT-LABEST, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4166-9379","authenticated-orcid":false,"given":"Paula","family":"Milheiro-Oliveira","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"Mathematical Research Center (CMUP), Faculty of Sciences, University of Porto, 4099-002 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6371-0179","authenticated-orcid":false,"given":"Lino","family":"Maia","sequence":"additional","affiliation":[{"name":"CONSTRUCT-LABEST, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"Faculty of Exact Sciences and Engineering, University of Madeira, Campus da Penteada, 9020-105 Funchal, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,20]]},"reference":[{"key":"ref_1","unstructured":"Nunes, S.
