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.

近年来，规定设计强度为360 - 420 kgf/cm^2、30 - 40层的超高层钢筋框架式公寓在日本的主要建筑中流行起来。因此，本文对各种水泥（普通硅酸盐水泥、粉煤灰水泥、硅酸盐高炉矿渣水泥）、试件（模型试件、模筒试件）、粗骨料（混凝土用碎石、人工轻骨料）、水灰比（30、35、40、45、50%）和养护（标准养护、水养护、密封养护、风干养护）的高强混凝土进行了综合评述。每立方水水泥为170公斤。采用高效减水剂和高效减水剂配制坍落度为21cm的混凝土。主要研究了come试样和圆柱体试样对抗压强度、杨氏模量、抗拉强度、脉冲速度、回弹次数的影响。
