Experimental study on the property up-grading for SCC with bamboo-charcoal application

This research studies the properties of self-compacting concrete by applying bamboo-charcoal to improve the fresh concrete property, physical property and micro-scale property.Conventionally, the Pozzolanic materials used in the self-compacting concrete are fly ash and slag. They are used to replace part of the cement such that the flowing property and compacting property can reach the requirement of the self-compacting concrete. According to previous research the bamboo-charcoal can absorb part of water, and enhance the early strength of concrete.
In this study, we use bamboo-charcoal to replace parts of the fine-aggregate in the mixture of self-compacting concrete. The replacement ratio is designed as 0‰,2‰,3‰,3.5‰,4‰ and 5‰. From the experimental test of fresh concrete property, we can evaluate whether the concrete mix design can achieve the requirements of self-compacting concrete. Test for the compressive strength development, water absorption and rapid chloride penetration test are performed to evaluate the physical property of concrete. In addition, the scanning electronic microscope photos are taken to examine the microstructure of the concrete. In our results, it is found that the best proportion of replacement is 3‰. The requirements of self-compacting concrete can be satisfied, and the development of strength is also good.
