INFLUENCES OF CALCIUM SOURCES, CONCENTRATION OF THE CEMENTATION SOLUTION AND TYPE OF SAND ON MICROBIAL INDUCED CARBONATE PRECIPITATION
Journal Title: International Journal of Civil, Structural, Environmental and Infrastructure Engineering Research and Development (IJCSEIERD) - Year 2017, Vol 7, Issue 2
Abstract
MICP technology is relatively one of the new technology emerge in the field of improving the soil. Therefore, this technique needs more intensive research before it becomes usable in widespread. This research aims to study the effect of calcium source type, concentration of the cementation solution, the soil type, the use of cementation solution consists of a combination of calcium sources, on the calcium carbonate content, the crystal formation, the porosity, and the strength. Set of laboratory tests were conducted, including porosity, calcium carbonate content, unconfined compressive strength and microscopy investigation (SEM). The results presented in this study revealed that using the cementation solution composed of calcium acetate and calcium chloride, which is made of egg shells and urea with MICP technique can improve the mechanical properties of the fine sand. Also, the use of a cementation solution containing variety mixtures of calcium sources did not show any noticeable difference in improving the properties of treated sand compared with sand treated with a cementation solution containing one type of calcium. The use of low concentrations of cementation solution provides a greater improvement in the engineering properties of the treated soil.
