This study is an experimental work that covers the development and production of alkali activated concrete (AAC) in a ready mix concrete (RMC) plant for the construction of a demo structure of a one-story with a plinth area of approximately 90m2 . AAC formulated with a glass granulated blast furnace slag (GGBS) to fly ash (FA) ratio of 70:30 serves as an ecofriendly and sustainable alternative to ordinary Portland cement (OPC) cement concrete. The research addresses the critical gap between laboratory study and on-site application, providing data to support the standardization and widespread implementation of AAC in the construction industry. The focus area of the research is a) High workability and its Retention at the site b) Ambient curing capability c) Validating structural performance through in-situ load testing. The AAC mix of grade M35 was developed after several iterations to achieve the desirable characteristics suitable for RMC construction as an alternative to OPC concrete. The collapsible slump is obtained at the batching plant, and after 1 hour, the slump is found to be around 150 mm for the mix. The temperature of the alkali activator initially reached around 70°C upon mixing. The temperature regulation is crucial to optimizing mixing conditions and ensuring safe handling. The successful retention of workability over an extended period led to the successful implementation of ready mix AAC. The Load-deflection testing of the structure confirmed more than 91 % recovery and compliance with safety criteria. Embedded and surface-mounted strain gauges revealed linear strain distribution, aligning with bending theory. The construction of demo structures with AAC using RMC helps in understanding the challenges of using AAC in construction projects. This study is an important step towards AACs viability in RMC applications, advancing sustainable construction practices.
