Tóm tắt

Granulated Blast Furnace Slag has been used for concrete admixtures for a long time in Vietnam, but it has not noticed for many other purposes of construction. Many factories of iron and steel productions in Vietnam are not interested in GBFS. The quality of GBFS is often unstable, its composition and properties are often changed. This is one of the barriers to the widespread adoption of GBFS. This paper focuses on the engineering properties of GBFS as a basis for applicability assessment to construction materials. The obtained results indicate that GBFS in Vietnam have grained grade in range of medium to course size, bulk specific gravity is approximate 1.0 g/cm3, specific gravity is less than 2.3 g/cm3 and content of CaO and SiO2 is around 35-38%. It is suitable for civil engineering works and ground improvement materials. However, it should be noted that direct use of GBFS for concrete and mortar will meet difficult and not suitable, so this possibility of application should be further studied.
