海报摘要

Recently, a rapidly growing effort was opened by the production of innovative cement free flowable concrete towards decreasing the emissions of GHG to the atmosphere. Alkali activated materials would replace cement based concrete completely and would meet the sustainability criteria directly. The development of AASCC from an increasingly diverse range of waste based precursors and activators has r estricted its popularity, standardization, and production. The present study aimed to design and conduct an experimental program to examine the potential production of one part AASCCs. Also, exploring the effect of the nature, concentration, and combinatio n of various source materials and dry powder activators on AASCC fresh and hardened properties cured under ambient curing conditions.
