Utilization of Soybean as Catalyst Material in Enzyme-Mediated Calcite Precipitation (EMCP) for Crack Healing Concrete
2020
Journal of the Civil Engineering Forum
This paper discussed the effect of soybean as the catalyst in the Enzyme-Mediated Calcite Precipitation (EMCP) method for crack healing concrete. The existence of cracks in the concrete will reduce the quality of the concrete, so it needs concrete repair efforts, one of which was by injection using the EMCP method. The EMCP technique employs the plant-derived urease enzyme catalyze the reaction between calcium chloride (CaCl2) and urea (CH4N2O) to precipitate as calcium carbonate (CaCO3). The
