However, this paper studied the durability properties of self-compacting concrete modified with millet husk ash (MHA) subjected to different environmental conditions such as sulfate attack from sulphuric acid and magnesium sulfate salt, elevated temperature, and water absorption. Grade 40 (control) SCC obtained from serries of trial mixes using 0.35 water-cement ratio was used for this study. Other mixes were derived from the control mix by replacing cement with 5, 10, 15, 20, 25, and 30 % by weight of MHA, respectively. The effects of sulfate elevated temperature, and water absorption was evaluated for all mixes. The experimental results of this work showed that the MHA is a pozzolanic material and can reduce the ingress of water and sulfate attack on concrete. However, the addition of MHA reduces the heat-resisting capacity of concrete.</em></p><p class="Body"> </p> |
