The thermal transformations of the metavolcanics involved the gradual replacement of their low-temperature mineral assemblage (actinolite + albite) by a higher temperature one (clinopyroxene + amphibole + andesinebytownite ± olivine).
      
The results of calculations for the model aqueous electrolyte solution-mineral assemblage suggest high SiO2 solubility in the metamorphogenic fluid.

The fly-ash was mixed with limestone and a few gypsum as a raw material and burned. We obtained a clinker with C_3S and C_4A_3S as dominant components. Its strength is high in early stage. Furthermore, using about 40% fly-ash as an addition to the clinker and grinding them together, we can make a blended cement with 325~425kg/cm~2 compressive strength, according to our National Cement Standard. Its early strength is nearly as that of the portland cement of the same grade.With the addition of certain quantity...

The fly-ash was mixed with limestone and a few gypsum as a raw material and burned. We obtained a clinker with C_3S and C_4A_3S as dominant components. Its strength is high in early stage. Furthermore, using about 40% fly-ash as an addition to the clinker and grinding them together, we can make a blended cement with 325~425kg/cm~2 compressive strength, according to our National Cement Standard. Its early strength is nearly as that of the portland cement of the same grade.With the addition of certain quantity of SO_3 and a few amount of CaF_2 to the system of CaO-SiO_2-Al_2O_3-Fe_2O_3, the temperature of the formation of C_3S can drop considerably and, in the clinker, it can form a certain quantity of C_4A_3S and others, which are beneficial to early strength. It has been confirmed by the study of mineral formation procedures in laboratory and by the pilot study with a rotary kiln of φ3.1/2.5×78M.If the additive quantity of gypsum and fly-ash is controlled appropriately, the cement can be made with good properties. The authors suggest it will be the new type of cement used widely in future.

In this paper, the general classification of sedimentary type uranium ores in China and their relationship to leaching characteristics is studied. It has been found through tests that five distinct characteristic types of minerals belonging to sedimentary type uraniferous ore i.e., carbonates minerals,clay minerals, sulphides minerals, fossile organic matter and apatite are of major technological and economical significance to the selection of leaching method and technological parameters. Hence, the division of sedimentary type uraniferous ores into eight classses is proposed as follows: ( 1 ) uranium ore amenable to acid leaching with low contents of the above minerals;

The domain of clay mineral is a primary structural unit of clayey soil. In fact, the influence of clay mineral on the engineering properties of clayey soil is given by the domain, but in varying structure systems the extent of this influence is different. In the remoulded sample of clayey soil the nature of domain can be sufficiently presented, thus effect of the mineral composition on the soil behaviour is more explicit. In the undisturbed clayey soil the nature of domain is restrained by other structural factors,...

The domain of clay mineral is a primary structural unit of clayey soil. In fact, the influence of clay mineral on the engineering properties of clayey soil is given by the domain, but in varying structure systems the extent of this influence is different. In the remoulded sample of clayey soil the nature of domain can be sufficiently presented, thus effect of the mineral composition on the soil behaviour is more explicit. In the undisturbed clayey soil the nature of domain is restrained by other structural factors, hence influence of the mineral composition on the engineering properties is far less in the undisturbed clayey soil than that of the remoulded sample. For assessment of the influence of clay mineral on the engineering properties of clayey soil, the structural characteristics of soil must be considered accordingly.

叠片体是粘土矿物在土中存在的基本形式,也是粘性土结构重要的基本单元。实际上粘土矿物是以其叠片体来影响工程性质的,影响程度在不同的结构体系中是有差别的。在重塑土中由于结构具有以叠片体表面溶剂化层间接接触为主的特征,矿物叠片体的本性得以充分显示,故粘土矿物组成对工程性质的影响比较显著。在天然的原生结构土中矿物叠片体的本性受到制约,因而对工程性质影响的不及重塑状态明显。所以在评价粘土矿物对粘性土工程性质影响时,必须结合土的结构特征统一考虑。
