In recent years, super high-rise reinforced frame-type apartment buildings with specified design strength of 360 to 420 kgf/cm^2, rangings 30 to 40 stories, have become popular in Japan among leading construction.Therefore, this paper presents to a comprehensive review of high-strength concrete with kinds of cements ( normal portland cement, fly ash cement, portland blast-furnace slag cement ), test specimens ( model test specimen, molded cylinder test specimen ), coarse aggregates ( crushed stone for concrete, artificial light-weight aggregate ), water cement ratios (30, 35, 40, 45, 50 % ) and curings ( standard curings, water curings, seald curings, air-dry curings ). The water cement per cubic was 170 kilograms. The concrete was 21cm slump were prepared by using superplasticizer and high-range water reducing agent.Effect of compressive strength, Young's modulus, tensil strength, pulse velocity, rebound number by come test specimen and cylinder test specimen were chiefly studied.
