Manufactured sand (M-sand), Granulated Blast furnace Slag (GBFS), stone crusher dust, Quarry dust, Washed bottom ash, sheet glass powder etc. II OBJECTIVES . The aim of this study is to determine the strength of cement mortar, replacing fine aggregate with Granulated Blast furnace Slag (GBFS) by various percentages such as
Experimental studies were performed on the use of non-ground-granulated blast-furnace slag as an aggregate in concrete. Using industrial by-products can help reduce greenhouse gas emission, and can be more economical than normal Portland cement concrete. While grinding the slag puts an additional burden of cost into production, using them as a partial fine aggregate does not …
Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the …
The present Investigation has been undertaken to study the effect of blast furnace slag and crusher dust on the mechanical properties of concrete, when coarse aggregates is replaced by blast furnace slag and crusher dust is replaced with fine aggregate in different percentages i.e. 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and .
treatment (this slag is sometimes called "secondary refining slag" or "ladle slag"). As shown in Fig. 1, nearly 80% of blast furnace slag is granulat-ed slag produced by rapidly cooling hot molten …
Capacity: 3-15t/h Applicable Materials: It can be used for comminution of mixture, gypsum, coal grinding stone, slag, copper ore and other materials. It is also one of the most common …
