HIGH DENSITY AND HEAVY WEIGHT FINE AGGREGATE
The high-density heavy fine aggregate of the present invention contains 3 to 25 wt% of residual of No 4 sieve; 15 to 25 wt% of residual of No 8 sieve; 15 to 25 wt% of residual of No 16 sieve; 10 to 15 wt% of residual of No 30 sieve; 5 to 10 wt% of residual of No 50 sieve; 5 to 10 wt% of residual of No 100 sieve; 8 to 15 wt% of residual of No 200 sieve; and 2 to 10 wt% of residual of Pan. In addition, the high-density heavy fine aggregate according to the present invention preferably has an absolute dry density of 3.1 ton/m^3 or more and a unit volume mass of 2.17 ton/m^3 or more.
본 발명의 고밀도 중량 잔골재는 No 4 번체의 잔유율 3 ~ 25 중량%; No 8 번체의 잔유율 15 ~ 25 중량%; No 16 번체의 잔유율 15 ~ 25 중량%; No 30 번체의 잔유율 10 ~ 15 중량%; No 50 번체의 잔유율 5 ~ 10 중량%; No 100 번체의 잔유율 5 ~ 10 중량%; No 200 번체의 잔유율 8 ~ 15 중량%; Pan의 잔유율 2 ~ 10 중량%;를 포함한다. 아울러, 본 발명에 따른 고밀도 중량 잔골재는 절대건조밀도가 3.1ton/㎥ 이상이고, 단위용적질량이 2.17 ton/㎥ 이상인 것이 바람직하다.
