硅酸盐水泥

Acoording to the dense system mortar theory sith micromeritics added to cement to produce impermeable gel with expansive property.The expansive concretepossesses both early expansivity (during 14d water cure) and later expansivity (during 286d shrinkage period in air).

依据与水泥生成超细粒致密系统浆体理论，利用天然非金属硅酸盐矿物与水泥形成不透水凝胶体的特有膨胀性能，研制出高抗渗、抗收缩的TEA－膨胀型防水剂。

The compressive strength's difference of autoclaved materials samples before or after admixed gypsum and effect of gypsum amount on compressive strength of the autoclaved samples were studied.

石膏的加入明显改善水泥性能的作用机理及其存在形式已经明确，它作为蒸压硅酸盐制品的激发剂，以及在蒸压硅酸盐制品中的存在形式也有大量研究[1，2]。

On the basis of survey of many marine concrete constructions,the effects of adding slag powder,fly ash,silica fume to Portland cement on the performances of marine concrete were researched.

在调查分析海工混凝土工程实例的基础上，试验研究了硅酸盐水泥中掺入矿粉、粉煤灰、硅灰等混合材料对海工混凝土性能的影响。

Ground fly ash and silica fume which have great positive influence on GRC's long-term durability are important factors to improve the flexural and compressive strength in the later stage and among them the silica fume has greater contribution.

而使用活性掺合料改善用普通硅酸盐水泥做基体的GRC耐久性时，又会带来GRC的早期强度过低及脱模时间过长的问题。

Aiming at these factors,our main ameliorative measures are:as following:adopting " three-high rates " composition,in a specific way,three rates should choose KH:0.88-0.92,SM:2.6-2.8,IM:1.6-1.8,and controlling the content of R2O,SO3,this method can insure that the content of silicate mineral is higher than 77%,especially the content of C3S is lower than 55%,so it can compensate for insufficient of descending of cement strength resulted by inactive component after implementing the checking method of ISO cement strength.

针对这些因素的主要改进措施为：采用&三高&配方，即三率值宜选择为KH0.88～0.92、SM2.6～2.8、IM1.6～1.8，并控制好R_2O、SO_3含量，以此保证水泥中的活性组分即硅酸盐矿物的含量≥77％，特别是C_3S含量不能低于55％，这样就能弥补因实施ISO强度检验方法后，水泥中非活性组分导致强度下降的不足。

Since then, the slag Portland cement and the durability of a good value for the people by constantly understanding of the early 19th century in Europe has been widely used.

自那时以来，矿渣硅酸盐水泥和耐久性的一个很好的价值的人不断了解19世纪初在欧洲已得到广泛应用。

Portland cement are also used in the manufacture of many other construction materials.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
