| 4. | The 5 batches with 31 groups of specimens were carried out four different curing systems including standard curing , hot water curing , dry heat curing and steam curing , and the regularity of rpc200 ' s strength with different curing conditions was studied . a conclusion was acquired by the experiment that the rpc200 ' s strength develops steadily in the steam curing which is mature and the economic benefits is more notable
制作四批23组试件，进行了标准养护、热水养护、高温干热养护、蒸汽养护等四种不同的养护制度的对比试验，通过试验研究发现采用蒸汽养护的rpc200后期强度发展稳定，并且蒸汽养护技术成熟，养护设备无需改造就可用于rpc200构件的养护，具有显著的经济效益。

| 5. | But the chemical properties have no remarkable influence on it ( 3 ) as the water - to - binder reduces wich is one of key factors in the perpormance of reactive powder concrete with steel slag , the fluidity decreases but the strength increases ; incorporation of 4 percent steel fiber in volume can decrease fluility and increase strength ; heat - curing benefits the increase of strength which can still develop in 28 day water curing after heat - curing
( 3 )水胶比是影响其性能最为关键因素之一，随着水胶比的降低，流动性下降和强度的提高都很明显；掺入4的钢纤维对流动性的影响比较明显，同时也不同程度地提高了强度；热养护有利于强度的提高，经热水养护后放置水中至28天龄期，其强度有较大提升，并没有出现强度倒缩现象。

| 6. | Incorporating with mineral admixtures could control the tendency of evening shrinkage of hpc , but the effect is not much remarkable . and the expansive agent uea could compensate shrinkage , but different curing conditions have significant effects on the volume stabilization of hpc . it is necessary to enhance the water curing at the young age and try the best to prolong the curing time
本文对高性能混凝土体积稳定性的特点及其补偿措施进行了系统的研究，主要包括：指出了水胶比对高性能混凝土体积稳定性的影响；分析了掺矿物外加剂高性能混凝土体积稳定性的特点；研究了联合掺加矿物外加剂和膨胀剂对高性能混凝土收缩的补偿效果；探索了用膨胀型中热水泥来配制高性能混凝土对收缩的改善。
