Outline of Final Research Achievements

The purpose of this study was to investigate the possibility of utilization of Mongolian fly ash in the construction industry. We have conducted the following studies under this research: 1. Interviews in Ulaanbaatar to understand current conditions of usage and the inhibition factors of dissemination of use of fly ash. 2. Research on the optimal mix proportion for fly ash brick industry 3. Experiments to find effect of anhydrite in fly ash in giving a high compressive strength.
We have obtained the following results:1. We have found that non-uniformity of fly ash and radioactivity of fly ash inhibit the usage. 2. Utilization of slag cement with the cement to calcium hydroxide ratio is 1.43 gives the optimum blend with the highest compressive strength and the lowest CO2emissions. 3. Fly ash with anhydrite gives the higher strength than fly ash without anhydrite at all ages. It has found that this optimum content of anhydrite in fly ash would be 1.5-2.5kg/m3 of concrete.
