Effective microorganism solution-imbued sustainable self-curing concrete: Evaluation of sorptivity, drying shrinkage and expansion
Production of various concrete elements at early ages requires careful water curing to ensure the development of a hydration reaction that fills and discontinues the capillary voids, thus achieving the desired strength of the hydrated products. The effects of EM solutions at various contents on the strength development, sorptivity, drying shrinkage, expansion, and microstructures of the proposed concrete were determined.
Durability performance of modified concrete incorporating fly ash and effective microorganism
Environmentally sustainable construction materials with reduced carbon footprint have ever-growing demand worldwide. Based on this factor, some modified cement concrete mixtures incorporated with optimum ratio of fly ash (FA) and effective microorganism (EM) were produced. The strength performance, water absorption, resistance to aggressive environments (sulfuric acid and sulphate) and microstructures of the proposed concretes was evaluated.

As a result, the surface temperature of the mortar mix was reduced up to 8% and the thermal conductivity shows appropriate insulating materials.
The potential of effective microorganism (EM) inclusion in enhancing the properties of cement paste and concrete
Experimental works in this present study showed the incorporation of EM in cement paste increased up to 40% compressive strength and leading to produce low porosity which decreased at least 19% corresponding to cement paste without EM. However, the hydration process was completed longer than specimens without EM due to the earlier reaction of dehydration and decarbonation detected using thermogravimetric (TGA/DTG) test and presence of potassium thulium chloride in EM solution.
