To examine the appicability of the converter slag to aggregate, tests were performed for the converter slag specimens which were aged with steam, and the stability of expansion was investigated. The strength of the converter slag was found to be lower than that of the natural aggregate. But the strength of the concrete mixed with the converter slag and the granular slag was increased with an increase of the content of the granular slag. The slump value was larger for the specimen of the converter slag than that for the natural aggregate. The specific weight of the converter slag was decreased with an increase of the aging peroid. The aging time for the converter slag was accessed to be about 48 hours to accommodate the full stability of the expansion. The amount of the steam needed to age one ton of converter slag to full expansion was accessed to be 60 kg. From the regression analysis for splitting tensile strength (t), and flexural strength (f), the compressive strength (c) based on the following formulas were proposed σ<sub>t</sub>=0.1506·σ<sub>c</sub>+4.5(kg/cm<sup>2</sup>) (σ<sub>f</sub>=0.1537·σ<sub>c</sub>+30.5(kg/cm<sup>2</sup>).

To examine the appicability of the converter slag to aggregate, tests were performed for the converter slag specimens aged with steam, and the stability of expansion was investigated. The strength of the specimen was determined through the fracture test, and the results were summarized as follow. The strength of the converter slag was found to be smaller than that of the natural aggregate. The strength of the concrete mixed with the granulate slag was increased with an increase of the content of the granulate slag. The slump value was larger for the specimen of converter slag than that for the natural aggregate. The specific weight of the converter slag was decreased with an increase of the aging peroid. The aging time for the converter slag was accessed to be about 48 hours to accommodate the full stability of the expansion. The amount of the steam needed to age one ton of the converter slag to the range of full expansion was accessed to be 60 ㎏. From the regression analysis of the correlations among the compressive strength (σ_c), tensile strength (σ_t), and flexural strength (σ_f) the following formulas were proposed. σ_t=0.150681·σ_c+4.451729 σ_f=0.1537·σ_c+30.47224

To examine the applicability of the converter furnace slag from iron-works as concrete aggregate respective concrete furnace slag with contents of 20%,40%,60%,80% were mixed with granulated slag, and the strength and stability tests for these specimens were followed. The slump value of the concrete mixed with converter furnace slag was higher than that of the conventional concrete. Furnace slag and granulated slag was increased as the increase of converter furnace content. The strength of the concrete mixed converter furnace slag and granulate slag increased as an increase of converter furnace content and age. The expansion rate of the concrete mixed with converter furnace slag and granulated slag increased from 0.007% to 0.19% as the converter furnace content changed from 20% to 80%. From the above results in the strength and expansion rate, the concrete with the converter furnace content of 40% was considered to be recommandable for the stable construction of the concrete. Calculated formalas for tensile strength (σ_t) and flexural strength(σ_f) from the regression analysis of the correlations among these compressive strength (σ_c) tensile strength and flexural strength are as follows. σ_t = 0.16952σ_c - 4.9313 σ_f = 0.25727σ_c + 6.0528
