Description
Summary:Self-healing concrete (SHC) is a concrete material innovation which can cure a crack on the concrete by microorganism supplementary as a healing agent. Besides, plastic is a material frequently utilized, yet it increases the amount of plastic waste in environment. Thus, the plastic waste has been developed as a synthetic fiber inside the concrete. Plastic waste supplementary in SHC has potential in increasing mechanic characteristics on the concrete. However, research discussing plastic waste substitution in SHC has been uncovered. This research aimed at analyzing load strength value ability accession, elasticity modulus, strength of tensile, and evaluation result resulted from crack cover of SHC Bacillus subtilis bacteria based with the substitution of plastic waste on the concrete was normal. This study employed experimental method by utilizing two compositions of concrete: A’s composition (bacteria concrete and plastic fiber) and R (normal concrete). Both of compositions later would be molded consisting of 3 cylinders 150×300 mm and 3 prism 75×75×150 mm. Next, the treatment was undertaken for 28 days before testing. To evaluate the crack, the tested concretes were placed into three different treatments; indoor, outside, and immersed on water. Furthermore, the research showed the elasticity modulus value, and it decreased up to 7.75%, compared with normal concrete. The crack closure evaluation showed that crack closure in concrete by immersed on water by coverage as calcium carbonate sediment in the crack area on the 14th and 28th compared with other treatment.
