硬化体

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.

由图象分析可知，即C原材料的比例及颗粒度符合密实堆积原理，堆积物的孔隙率达到最小；差示扫描量热分析表明，RPC的水化反应速度很快，主要的水化过程集中在较短时间内；扫描电镜及X衍射试验表明，RPC硬化体的结构非常致密，主要由一些不规则状的扁平粒子紧密堆积在一起，水化产物主要是Ⅲ型C-S-H， Ca2晶体的量稀少且没有钙矶石。

The tests study influence of L retarder on setting time, hydrating characteristics and setting strength of building gypsum in comparison with effective result of often used retarder－ citric acid and sodium pyrophosphate.

Pore structure experiment shows that porosity of high volume fine mineral mixture RPC is about 5%, the pore distribution is uniform and the main pore is small. When the cement content of high volume fine mineral mixture RFC is 300 kg/m^3, its sclerotium hydration products is dense packed by irregular equal Ⅲ style C-S-H gels. The gels are fine, dense, and integrate with the aggregate.

孔结构试验表明，大掺量矿物细粉活性粉末混凝土的孔隙率均在5%左右，孔分布情况很均匀，主要以微小的小孔为主；水泥用量为300 kg/立方公尺的大掺量矿物细粉活性粉末混凝土硬化体水化产物主要由不规则等粒子状的Ⅲ型C-S-H凝胶紧密堆积在一起，凝胶精细、致密，且与骨料融为一体。

Mortar specimens were prepared, in which finely pulverized zirconite which is inactive under the reaction condition of this experiment was used to replace ground carbonatite or ground granulated blast-furnace slag isometrically, so as to investigate the contribution of each material to the performance of the products.

本文采用无活性的锆美石分别等体积替代碱激发碳酸盐矿-矿渣胶凝材料中的碳酸盐矿和矿渣，考察此三个体系的强度变化以及通过DTA分析存在协同效应的可能性，进而通过净浆硬化体的孔溶液成分分析研究复合作用机理。

This indicate that pozzolanic reaction of X FLOUR is adquate.

表明X粉火山灰反应充足，对硬化体微结构改善明显，因而增强效应显著。

With good water proof property and corrosion resistance,its hardened body can recrystallize after its bearing discruption.

其硬化体有良好的耐水性和耐腐蚀性，在承载破坏后还具有重结晶性。

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。

The experimental results show that the reactivity of calcined kaolines from the same origin is different after they are calcined at different temperatures,their reactivity reach the biggest value after the kaoline is calcined at 800℃ for 6h;the reactivity of calcined kaolines from different origins are much different after they are calcined at different temperature...

试验结果表明：产地相同的高岭土经不同温度活化，其活性大小不同，在800℃煅烧6h后，其活性达到最大值；产地不同的高岭土经相同温度活化，其活性大小相差很大；用该方法所测定的偏高岭土的活性Al2O3和SiO2总量的大小与其地质聚合物硬化体的抗压强度和NH4+交换容量有相关性。

The paper introduced in brief the basic chemical and mineral component, and analysed the effect and the evaluation index of the chemical component, vitreous body quantity and structure and the fineness degree of the phosphorus slag on its chemical activity, and finally, discussed the effect of phosphorus slag as additive on cement hydration property and the micro structure of the harding body.
