A Study on Eco-Concrete Incorporating Fly Ash and Blast Furnace Slag in Construction in Vietnam

Abstract

Fly ash and ground granulated blast furnace slag (GGBFS) is a green construction material used to produce durable concrete. Experimental research on eco-concrete uses incorporating cement, fly ash and GGBFS. Fly ash and GGBFS replace different cement content by weighing, evaluating the workability, mechanical properties and durability of eco-concrete. The results also show that combining fly ash and GGBFS in concrete can create compressive strength concrete of 55MPa while the amount of cement used for 1m3 of co-concrete does not exceed 300 kilograms, the research also judges the water absorption, the chloride penetration resistance at 28 days with 30% replacement of GGBFS.
