The minor interaction between the cement paste [43] that caused the air cavities is related to how poorly concrete performed. The durability-related characteristics of concrete are negatively impacted by an increased air content [44]. Fig. 7 shows that the fresh mix air content rises when bamboo fibers are added to the mixture. This rise was 4 ...
