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.

This paper presents the results of an experimental study to determine the hydratedproducts produced from silicate products which are obtained from industrial refuse (fly ash, coal mine refuse, fluidized-bed ash, slag) mixed with lime and gypsum under 100℃steam curing or 175℃ autoclaving condition.

This paper presents the results of an experimental study to determine the hydratedproducts produced from silicate products which are obtained from industrial refuse (fly ash, coal mine refuse, fluidized-bed ash, slag) mixed with lime and gypsum under 100℃steam curing or 175℃ autoclaving condition. By the use of XRD, DTA, SEM and separa-tion with heavy liquid, it is found that in all the above silicate products, the calcium sili-cate hydrates formed under the condition of autoclaving will be the well-crystallized to-bermorite and ill-crystallized CSH(B) co-existing in its continuous phase and CSH(B)formed under the condition of steam-curing. In either autoclaving or steam-curing cases,Al~(3+) will enter the structure of calcium silicate hydrates to form the alumina-containingsilicate hydrates. The formation of the phase of hydrated products depends in a high de-gree not only on the temperature of reaction but also on the quantity of the lime mixed.Within a certain limit, the increasing of the quantity of lime mixed can help the forma-tion of tobermorite (including alumina-containing tobermorite) and hydrogarnet. Calciumsulphoaluminate hydrate (including high sulphated and low sulphated forms) can existonly under the condition of 100℃ steam curing.

本文采用X射线衍射、差热分析、扫描电子显微镜和重液分离等方法,对以工业废渣(粉煤灰、自燃煤歼石、沸腾炉渣炉渣)为主要原料,掺石灰、石膏的硅酸盐制品,在100℃蒸养和175℃蒸压条件下的水化产物作了鉴定,发现在所有上述制品中,在蒸压条件下形成的水化硅酸钙是结晶较好的托勃莫来石和结晶较差的CSH(B)同时存在的连续相;在蒸养条种下形成CSH(B)。但不论蒸压或蒸养,Al都进入水化硅酸钙的结构中,形成含Al的水化硅酸钙。水化产物的相组成,不仅与反应的温度有很大关系,而且因石灰掺量的不同而有明显差别。在一定范围内提高石灰掺量,对形成托勃莫来石(包括含Al的托勃莫来石)和水石榴石有利。水化硫铝酸钙(包括高硫型和低硫型)只在100℃蒸养条件下存在。

Two kinds of typical colliery shales i.e. illite and kaolinite were used as the test samples for investigation. These samples were burnt under the temp- eratures of 600, 700, 800, 1000, 1100, 1200, 1300 and 1400℃ respectively for two hours. Their mineral constituent were quantitatively determined by means of X-ray diffraction. The fineness and granularmetric distribution of the cinder grains were measured by the specific surface instrument and the sedimental balance, and the inner specific surface by the nitrogen adsorption method. The cinder was mixed together with lime, gypsum and water, and then the pastes were cast into moulds of 2×2×2cm. The strength of the pastes were measured after steam curing and autoclaving and compared with that of fly ash, and blastfurnace slay pastes prepared under the same process. The optimum active ranges for each composition were obtained for each burning tempera- ture. The experimental results show that the mineral compositions as well as the burning temperatures have important effect on the reacttitvity of burnt colliery shales. The amorphism and vitrification of the clay minerals are the key factors of the activity of the cinder and the kind and quantity of crystal- line phase in the cinder have a certain degree of effect on the reactivity. The results of semiquantitative analysis for the hydrates shows there exist a positive correlation between the strength of autoclaved lime-colliery shale cinder con- crete and the quantity of formed CSH gel, and a negative correlation between the strength and the quantity of hydrogarnet. By comparing the pozzolanic reactivity of the shale cinder, fly ash and blastfurnace slag, it may come to the conclusion that the strengths are different for different mineral comp- ositions under the same curing temperature and for the same composition but under different curing temperatures. The authors suggested that the implication of and the method for detering the puzzolanic activity of the cinder should be established respectively accord- ing to the curing process i. e. normal curing, steam curing or autoclaving.

采用具有代表性的以水云母和高岭石为主的两类煤矸石试样,分别在600~1400℃的温度下煅烧两小时。用X射线衍射分析方法进行物相定量分析。用比表面积仪和沉降天平测定其细度和颗粒级配。氮吸附法测定内比表面积。将以上灰渣与石灰、石膏制成2×2×2cm的净浆试块。测定蒸养、蒸压条件下的强度,并在相同试验条件下与粉煤灰、沸腾炉渣、矿渣进行对比。从中求得两类矸石最佳煅烧温度范围。研究结果表明,煤矸石灰渣的活性与矸石的组成,燃烧温度密切相关。矸石中粘土矿物的无定形化和玻璃化是灰渣产生活性的主要原因,而其中结晶相的种类和数量对灰渣活性也有一定的影响。水化产物定量和半定量分析证明,煤矸石硅酸盐混凝土蒸压强度与C-S-H凝胶生成量具有正相关性,与水柘榴石生成量具有负相关性。比较矸石渣、粉煤灰、沸腾炉渣和矿渣的活性均能发现,养护条件相同,灰渣成份不同强度不同。养护条件不同,灰渣成份相同强度也不同。因此建议应根据常温、蒸养、蒸压三种使用条件分别确定灰渣活性的含义和测定方法。
