Modified polycarboxylate polymers (G3) and lignin-based polymers (G1) were used as plasticizing admixtures and the results were compared to the effect of tap water addition. The results showed that all the admixtures used are effective in increasing the workability of the HCFA geopolymers mixtures and the workability increased by 25-48 compared to the control mixtures. However, the use of G3 has adversely affected the strength by a reduction of 20. While the use of G1 reduced the final setting time by 7 which is critical in the case of HCFA geopolymers where the final setting time occurs within 70 minutes. Water can be considered as the best admixture in terms of cost, setting time, and effect on compressive strength and it can be used where medium workability enhancement is required. © 2017 Trans Tech Publications, Switzerland. date: 2017 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85016205340&doi=10.4028%2fwww.scientific.net%2fKEM.733.76&partnerID=40&md5=9fc7358dd62edfc58503955d708a4b92 id_number: 10.4028/www.scientific.net/KEM.733.76 full_text_status: none publication: Key Engineering Materials volume: 733 KE pagerange: 76-79 refereed: TRUE isbn: 9783035710168 issn: 10139826 citation: Malkawi, A.B. and Nuruddin, M.F. and Fauzi, A. and Al-Mattarneh, H. and Mohammed, B.S.
