Abstract

Up to the present, the incorporation of Effective Microorganism (EM) in cement paste showed the huge potential as an additives in enhancing the compressive strength associated with low total porosity, pore volume and pore diameters measured using Mercury Intrusion Porosimetry (MIP). The findings showed the mercury intruded at small pore diameter for microbed cement paste while control cement paste without EM, mercury was intruded largely. Subsequently, the results obtained was corroborated with denser and lesser voids of internal microstructure in cement matrix. Furthermore, full inclusion of EM in cement paste was not encouraging due to the low compressive strength recorded. This result was supported with decrement peaks of cristobalite detected by X-Ray Diffraction (XRD) analysis which was influenced the strength development. Moreover, potential study in incorporating EM in concrete need to perform extensively due to high compressive strength and tensile splitting strength recorded in previous study.
