The Effect of Effective Microorganism (EM) Inclusion to the Setting Time of Microbed Cement Paste

The inclusion of Effective Microorganism (EM) lengthen the setting time of microbed cement paste with respect to the control cement paste. However, the investigation on the influence of EM ingredients to the setting time was not performed yet in the earlier study. Therefore, the test of X-Ray Diffra...
