  slag cement
A comparison between the model predictions and the experimental results in literature shows that the presented computer model can successfully predict the hydration process and the microstructure development of hydrating slag cement paste.
      
A newly developed version of a three-dimensional computer model for simulating the hydration and microstructure development of slag cement pastes is presented in this study.
      
Three-dimensional computer modeling of slag cement hydration
      
The model predictions are further used to calculate some properties of hydrating slag cement pastes, including the molar fractions of products, the water retention, chemical shrinkage and porosities of pastes.
      
Fiber-reinforced cement composites were produced in Brazil using blast furnace slag cement reinforced with pulped fibers of sisal originated from agricultural by-products.

The crystalline state of MgO, FeO and MnO in converter slag, open-hearth slag andelectric furnace slag from steel plants were studied and their reactivity with water undervarious autoclave conditions (at the temperature up to 330℃ corresponding to the pre-ssure of 127 atm) were determined. Results show that MgO presenting as solid solution with FeO and MnO is much moreinert than pure periclase and will not cause unsoundness. It is praticable for using steelslag to make steel slag cement or as cement...

The crystalline state of MgO, FeO and MnO in converter slag, open-hearth slag andelectric furnace slag from steel plants were studied and their reactivity with water undervarious autoclave conditions (at the temperature up to 330℃ corresponding to the pre-ssure of 127 atm) were determined. Results show that MgO presenting as solid solution with FeO and MnO is much moreinert than pure periclase and will not cause unsoundness. It is praticable for using steelslag to make steel slag cement or as cement additives and as aggregates of concrete.

本文研究了国内钢厂的转炉渣、平炉渣和电炉渣中 MgO、FeO、MnO的结晶状态,并在各种压蒸条件下(温度达330℃、压力则至127个大气压)研究了它们与水化合的能力及其对水泥石膨胀的影响。研究发现,以固溶状态存在的某些MgO比纯方镁石稳定得多。不会引起体积安定性不良。这一结论对于利用钢渣制造钢渣水泥,用作混合材以及用作混凝土骨料是具有现实意义的。

The newly revised standards relating to ordinarily used cements of our country-portland cement, ordinary portland cement, portland blast-furnace slag cement, portlandpozzolan cement and portland fly-ash cement,will be officially adopted from Jan. 1st 1980-Various technical data from research works on revision have been presented. Discus-sions have principally taken on the limitations of additions in various types of cement,MgO in clinkers, SO_3 contents and the test and gradation for...

The newly revised standards relating to ordinarily used cements of our country-portland cement, ordinary portland cement, portland blast-furnace slag cement, portlandpozzolan cement and portland fly-ash cement,will be officially adopted from Jan. 1st 1980-Various technical data from research works on revision have been presented. Discus-sions have principally taken on the limitations of additions in various types of cement,MgO in clinkers, SO_3 contents and the test and gradation for strength of cements. The reasons for establishment of two new types of cement——portland (witbout addi- tions ) cement and portland fly-ash cement, the upper limit of MgO in clinker changesfrom 4.5% to 6.0% (on 5~6% shall pass the autoclave test ), of SO_3 from 3.0% to 3.5%(4.0% for portland blast-furnace slag cement ), the strength test changes from earth-dry mortar test to plastic mortar test, the gradation of cement and the relation betweencement grades and concrete grades have been discussed in detail. Economical advantages from the revision of cement standards including more types ofcement produced, more resoures of raw materials utilized and improved quilites of ce-ment produced have been analysed particularly.

我国硅酸盐水泥、普通水泥、矿渣水泥、火山灰水泥、粉煤灰水泥等常用水泥的新标准即将于1980年1月1日全面实施。论文介绍了为修改标准所进行的大量科研工作,提出了标准修改的各项技术依据。着重讨论了水泥品种和混合材掺量、熟料中氧化镁指标、三氧化硫含量以及强度测试方法和标号划分等四个问题。对于增设硅酸盐水泥和粉煤灰水泥两个品种、熟料氧化镁指标从4.5%放宽到6.0%(5~6%时须经压蒸试验合格)、三氧化硫限量从3.0%放宽至3.5%(矿渣水泥放宽至4.0%)、强度试验方法从硬练法改为软练法、水泥新标号的划分以及水泥标号换算混凝土标号的经验公式等作了详细的论述。并对这次我国水泥标准修订后将在扩充品种、提高质量、资源利用及确保工程质量等方面产生的经济效果作了具体分析。

From the comparison made on formation, morphology, transformation, stability andexpansibility of ettringite (3CaO.Al_2O_3.32H_2O) in the hydration and harding between thegypsum slag cement and portland blastfurnace slag cement, the authors have broughtforward, in connection with the discussion on the mechanism of the activation of granu-lated blast furnace slag, a proportioning principle of preparing a non-shrinking or slightlyexpansive cement from portland cement clinker, slag...

From the comparison made on formation, morphology, transformation, stability andexpansibility of ettringite (3CaO.Al_2O_3.32H_2O) in the hydration and harding between thegypsum slag cement and portland blastfurnace slag cement, the authors have broughtforward, in connection with the discussion on the mechanism of the activation of granu-lated blast furnace slag, a proportioning principle of preparing a non-shrinking or slightlyexpansive cement from portland cement clinker, slag and gypsum.

本文主要研究钙矾石(3CaO·Al_2O_3·3CaSO_4·32H_2O,简称E盐),联系矿渣硅酸盐水泥和石膏矿渣水泥在水化硬化过程中的物理化学条件,探讨E盐的生成和作用。在这个基础上,进一步改变矿渣硅酸盐水泥和石膏矿渣水泥的组成,得到具有微膨胀特性的矿渣水泥,并论述E盐在这种矿渣水泥中的生成数量、速度、形态、稳定性及其膨胀作用。
