Title:
HEAVY CONCRETE COMPOSITION USING SLAG BY-PRODUCTS
Document Type and Number:
WIPO Patent Application WO/2011/040768
Kind Code:
A2
Abstract:
Disclosed is a heavy concrete composition which uses slag by-products, comprising: ground granulated blast furnace slag; slow-cooling electric-arc-furnace oxidising slag or steel-making slag atomised using fine aggregate; coarse aggregate; water; and a chemical admixture, wherein the components are based on 100 parts by weight of high-early-strength cement. Thus an environmentally friendly heavy concrete product can be made by substantially reducing the amount of carbon dioxide emitted and maximising the use of waste resources for preserving the natural environment which is different from the heavy concrete products that have been used on railway lines to date, by including large amounts of steel-making slag and blast furnace slag which are by-products of pig-iron and steel manufacturing processes.
