Question

几个句子的汉译英

1.结果表明：双掺石灰石粉和粉煤灰混凝土强度增强明显
2.并得到一组最优参数：水胶比0.3，石灰石粉掺量15%，粉煤灰掺量10%，砂率34%，混凝土抗压强度值最大
3.石灰石粉：生产石灰石碎石、机制砂时筛出的石屑、细粉，磨细至比表面积245000px2/g，其成品见图1，化学成分见表1
4.选择利用正交表L9（34）安排实验，实验组合如表4所示，具体配比掺量见表5，为了对比，设计了单掺石灰石粉，粉煤灰的对比实验，实验设计如表6、7所示
5.混凝土可以视为连续的颗粒堆积体系，石灰石粉颗粒比水泥颗粒小，一方面填充在水泥颗粒之间，改善了胶凝材料的颗粒级配颗粒的均匀性和细颗粒比例；另一方面石灰石粉可以填充到界面的空隙中，使水泥石结构和界面结构更为密实
6.同时，粉煤灰中玻璃态的氧化硅和氧化铝可以与水泥水化生成的氢氧化钙和水发生反应（二次反应），生成具有水硬性特点的水化硅酸钙、水化铝酸钙等
7.通过静态抗压强度对比实验表明：双掺石灰石粉和粉煤灰混凝土强度增强明显
8.

Answer 1

1. The results show that the double mixing limestone powder and fly ash concrete strength enhanced obviously
2. And get a set of optimal parameters: the water-binder ratio of 0.3, lime stone powder content is 15%, 10% dosage of fly ash and sand ratio 34%, concrete compressive strength value is the largest
3. Lime stone powder, limestone gravel, mechanism of sand production the screen out of stone chips, fine powder, fine grinding and the specific surface area 245000 px2 / g, the finished product as shown in figure 1, chemical composition as shown in table 1
4. Select the orthogonal table L9 (34) to arrange experiments, experimental combination as shown in table 4, ratio of concrete admixture is shown in table 5, in order to contrast, design the single doped lime stone powder, fly ash of the contrast experiment, the experimental design as shown in table 6, 7
5. Concrete can be regarded as continuous particle stacking system, lime stone powder particles smaller than cement particles, on the one hand, fill between cement particles, and improves the gelled material uniformity of the grain size distribution of particles and fine particles; Limestone powder can fill the gap to the interface on the other hand, make cement structure and interface structure more compact
6. At the same time, the fly ash in the glassy state of silica and alumina can react with water and cement hydration of calcium hydroxide (secondary reactions), generated with hydraulic characteristics of hydrated calcium silicate, and hydrated calcium aluminate etc
7. Through the contrast experiment shows that the static compressive strength double mixing limestone powder and fly ash concrete strength enhanced obviously

Answer 2

1.The results show that the double mixing limestone powder and fly ash concrete strength enhanced obviously。
