06. MINIMIZING EFFECT OF WHITE MARBLE POWDER TO SOIL ENVIRONMENT: A CASE STUDY OF LANG LANH DEPOSIT, LUC YEN DISTRICT, YEN BAI PROVINCE

Tóm tắt

The quality of both natural and man-made environment is essential to social-economic development in Luc Yen district. The relationship between environment and mining quarries were studied using factors such as the amount of discharged marble powder, soil, and marble powder content in soil. By applying anti-compressive level measure, the results show that marble powder does not harden soil. However, it increases anti- compressive of concrete containing marble powder. The discharged marble and marble powder that recovered were used as an additive in concrete and to make Feng Shui souvenir. Only one type of marble powder can adapt among three samples and only two out of six formulas show remarkable results. During grinding and polishing, marble is not suitable for making a souvenir. It needs to have more research to find the solution to recover marble powder for making construction material to replace sand in the river.
