Strength Characteristics Analysis of Steel Slag Hydrated Matrix

Abstract

Iron and steel making slag are byproducts of the iron making and steelmaking processes. To date, these types of slag have been widely used in cement and as aggregate for civil works. A new product developed in Japan called “SSHM” (Steel slag hydrated matrix) which is made mainly from slag and absolutely free from natural aggregate. Steel slag hydrated matrix has the following features:
1. Made from 100% recycled resources.
2. Same strength performance as ordinary concrete.
3. Low alkaline dissolution.
4. Excellent wear resistance.
5. Excellent growth of biofouling organisms in marine environment.
This research work has the following objective
• To investigate different basic properties such as compressive strength, flexural strength etc. of Steel Slag Hydrated Matrix in comparison with ordinary concrete.
• To determine the mix proportion of fly ash, lime, ground granulated blast furnace slag, steel slag and water to achieve the required strength.
