In addition, slump retention is more delicate than the commonly used slump value since it reflects the concrete mixture\u2019s durability for usage in civil engineering applications. In this study, the effect of three water-reducer additives was tested on concrete\u2019s workability and compressive strength from 1 day to 28 days of curing. The slump of the concrete was measured at the time of adding water to the mix and after 30 min of adding water. This study employed 0\u20131.5% (%wt) water-reducer additives. The original ratio between water and cement (wc) was 0.65, 0.6, and 0.56 for mixtures incorporating 300, 350, and 400 kg of cement. It was lowered to 0.3 by adding water-reducer additives based on the additives type and cement content. Depending on the kind and amount of water-reducer additives, w\/c, gravel content, sand content, crushed content, and curing age, adding water-reducer additives to the concrete increased its compressive strength by 8% to 186%. When polymers were added to the concrete, they formed a fiber net (netting) that reduced the space between the cement particles. As a result, joining the cement particles quickly enhanced the fresh concrete\u2019s viscosity and the hardened concrete\u2019s compressive strength. The study aims to establish mathematical models (nonlinear and M5P models) to predict the concrete compressive strength when containing water-reducer additives for construction projects without theoretical restrictions and investigate the impact of mix proportion on concrete compressive strength. A total of 483 concrete samples modified with 3 water-reducer additives were examined, evaluated, and modeled for this study.<\/jats:p>","DOI":"10.3390\/app13021208","type":"journal-article","created":{"date-parts":[[2023,1,17]],"date-time":"2023-01-17T01:41:20Z","timestamp":1673919680000},"page":"1208","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Modeling the Impact of Liquid Polymers on Concrete Stability in Terms of a Slump and Compressive Strength"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4306-3274","authenticated-orcid":false,"given":"Ahmed Salih","family":"Mohammed","sequence":"first","affiliation":[{"name":"Civil Engineering Department, College of Engineering, University of Sulaimani, Kurdistan Region, Sulaymaniyah 46001, Iraq"},{"name":"Engineering Department, American University of Iraq, Sulaimani, Sulaymaniyah 46001, Iraq"}]},{"given":"Wael","family":"Emad","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Komar University, Sulaymaniyah 46001, Iraq"}]},{"given":"Warzer","family":"Sarwar Qadir","sequence":"additional","affiliation":[{"name":"Civil Engineering Department, College of Engineering, University of Sulaimani, Kurdistan Region, Sulaymaniyah 46001, Iraq"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2429-4755","authenticated-orcid":false,"given":"Rawaz","family":"Kurda","sequence":"additional","affiliation":[{"name":"Department of Highway and Bridge Engineering, Technical Engineering College, Erbil Polytechnic University, Erbil 44001, Iraq"},{"name":"Department of Civil Engineering, College of Engineering, Nawroz University, Duhok 42001, Iraq"},{"name":"CERIS, Civil Engineering, Architecture and Georresources Department, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
