Peparation and Functionallity of New Cement Materials

水泥材料自古埃及时代起就被用作建筑结构的材料。这种水泥的优点在于它是一种水泥浆。(1)MSS生产，(2)低成本，(3)耐水，(4)高强度，(4)成型能耗低。本研究的目的是制造具有以下功能和优点的“新型水泥”。(1)具有光反射水泥材料通过控制水泥中掺入外加剂的方式产生微小的水泥水化产物，使其具有最紧密的堆积排列和良好的光反射性能，然后将其混合物抽至高真空中，然后在低温下保存。(2)未烧成的新瓷砖尽管光反射水泥材料在机械强度方面存在问题，(3)柔性水泥材料：通过控制生产条件、养护条件等，可使水泥具有柔韧性和剥离性。生物反应器水泥材料添加活性碳和石油饼的生物混凝土具有实用的机械强度和良好的污水净化功能，具有这些功能的新型水泥材料是通过在原子级控制水泥的水化，并在纳米级进行复合而成的。通过理清新型水泥的功能、结构和制备工艺之间的关系，使这些新型水泥材料能够为21世纪的地球环境保护和资源有效利用服务。

The cement materials have been used since the age of Ancient Egypt as the materials for the architectural structure. The merits of the cements are as fpollows. (1) mss production, (2) low cost, (3) water-woking, (4) high strength, and (4) less energy in forming. This study aims to make"New cements"which have the functions as shown next as well as these merits.(1) Cement Materials having the Light-Reflective Cement MaterialsThe cement materials which have the closest packed arrangement and the excellent light-reflectivity were educed by controlling to educe the minute cement hydrate in the way how admixture was added into the cements, and then its mixture was evacuated to a high vacuum and it was preserved in the low temperature after this.(2) Non-Sintered New TileThough the light-reflective cement materials had the problem in relation to the aspect of the mechanical strength, the new tile whose strength coresponded to that of the baked tile could be made by compounding it with the carbon fibers.(3) Flexible Cement MaterialsThe flexibility and exfoliativity coud be vested with the cement by controlling the educing conditions, the curing ones and so on, and educing the cement hydrate which had the two-dimensional expanse when the crystal of the cement hydrate was educed.(4) Bio-Reactor Cement MaterialsIt was known that the bio-concrete to which activated carbon and petroleum cake were added had the practical mechanical-strength and the excellent purificatory-fuction of the filthy water.The new cement materials which had these functions were made by controlling of the hydration of the cemet at the order of atoms, and compuding at the nano-scale. And by clearig the relations amoug the function, the structure and the preparation procedure of the new cements, these new cement materials will be able to be used for the preservation of the earth-environment of the 21 century and the effective application of the resources.
