Three-dimensional concrete printing (3DCP) is one such technology that has automated building process along with several benefits such as reduced material waste, reduced human hazard, and time savings. Traditionally, this technique utilizes cement to construct numerous structures, resulting in a significant carbon footprint and negative environmental impact. There is a need to find alternate solutions to reduce cement consumption. Alkali activation technology has replaced cement completely. The scope of development of alkali-activated 3D printable concrete utilizing agro-industrial byproducts is presented in this study. A review of the fresh and hardened properties of alkali-activated 3D printable concrete was the primary objective. The change in properties of 3D concrete mixes with the variation of additives that influence the ultimate strength parameters is presented. This study explores the curing conditions and in-depth behavior of uses of 3DCP in the construction industry. The environmental benefits over conventional concreting technology are presented. As per previous studies, the optimum mix composition per cubic meter concrete is 600\u2013700 kg\/m3 of binder content, 450 kg\/m3 of alkali activator solution, and 600\u2013800 kg\/m3 of fine aggregate content. This study contributes to the making of 3D printable alkali-activated concrete.<\/jats:p>","DOI":"10.3390\/en16104181","type":"journal-article","created":{"date-parts":[[2023,5,18]],"date-time":"2023-05-18T10:17:26Z","timestamp":1684405046000},"page":"4181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Development of Alkali-Activated 3D Printable Concrete: A Review"],"prefix":"10.3390","volume":"16","author":[{"given":"Syed","family":"Mujeeb","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, India"}]},{"given":"Manideep","family":"Samudrala","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, India"}]},{"given":"Bhagyashri A.","family":"Lanjewar","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1698-8282","authenticated-orcid":false,"given":"Ravijanya","family":"Chippagiri","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9037-4887","authenticated-orcid":false,"given":"Muralidhar","family":"Kamath","sequence":"additional","affiliation":[{"name":"General Manager\u2014Technical Services, Apple Chemie India Private Limited, Nagpur 440022, India"}]},{"given":"Rahul V.","family":"Ralegaonkar","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, India"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,18]]},"reference":[{"key":"ref_1","unstructured":"(2023, February 02). 3DCP Database.
