| 1. | They were members of what was called the ash can school of realistic painting 他们是写实绘画的烟灰缸画派中的成员。 |
| 2. | Saponification slag - fly ash can be used in the high fill sections of highway 皂化渣粉煤灰可以用做桥头等高填土路段的回填材料。 |
| 3. | Thus , measuring carbon content of fly ash can help to know boiler burning state 因此,检测燃煤锅炉的飞灰含碳量可以直接了解锅炉的燃烧状态。 |
| 4. | The beginning experiment shows : after disposed by this installation , the doffmg - charcoal rate of original fly ash can achieve 29 % 初步试验结果表明,原状粉煤灰经本试验装置脱炭处理后,脱炭率达到29 ,具有一定的脱炭效果。 |
| 5. | The ratio of strength to cost is introduced to discuss the problem in which whether high volume fly ash can reduce the cost of concrete 针对掺用大量粉煤灰是否可以降低混凝土成本的问题,本文引入强度成本这个指标作了一些探讨。 |
| 6. | The excellent quality of coating film based on waterproof two - component polyurethane coating filled with fly ash can be gained when the fineness of fly ash is 300 meshes 当粉煤灰的细度为300目时能得到性能优良的双组分聚氨酯防水涂料。 |
| 7. | On the basis of ways of six ingredients , fly ash can be put into high strength and high performance concrete whose reliability of strength is very high 采用六组分路线配制粉煤灰高强高性能混凝土,揭示了其应用到高强高性能混凝土中的具有较高的可靠性。 |
| 8. | The separate addition of micro - silica , ultra - fined slag , high quality fly ash can improve the cement concrete ' s anti - chloride permeability . the result is micro - silica grater than slag grater than fly ash , and the greater the amount that added the greater the improvement is 5 x而水化产物对氯离于的固化主要为水化氯铝酸钙( friedel盐)生成及c s h凝胶体的层间物理化学吸附作用。 |
| 9. | The results of research on the workability of hbc concrete show that hbc concrete , when compared with opc concrete , has excellent compatibility with superplasticizer , in terms of better initial fluidity , less slump loss , definite saturation point and less dosage at saturation point . in addition , good mineral admixture such as i class fly ash can obviously improve the workability of hbc concrete . moreover , hbc concrete exhibits more excellent workability under the condition of low w / c ratio , which indicates hbc is more suitable for making super high strength concrete whose w / c ratio is very low 对高贝利特水泥高性能混凝土工作性能的研究结果表明,高贝利特水泥与高效减水剂具有良好的适应性,表现为初始流动度较大,经时损失较小,具有明显的饱和点且饱和点掺量较小;此外,优质的矿物掺和料如一级粉煤灰能明显改善hbc混凝土的工作性能;更为突出的是hbc混凝土在低水胶比的情况下表现出更为优异的工作性,这一特性预示着高贝利特水泥更适宜配制水胶比很低的超高强混凝土。 |
| 10. | The research results show that when the fly ash content is under 30 % , the strength of rcc can be increased but the effect is a little ; and with the fly ash content increased the dry shrinkage of the rcc reduced straightly , and the abrasion resistance and freeze resistance increased obviously . ( 3 ) fly ash can increase durability of the rcc and under the experiment condition , the perfect mixing content is 30 % 试验结果表明: ( 1 )粉煤灰掺量小于30 %时能提高碾压混凝土强度但影响度不大; ( 2 )随着粉煤灰掺量的增加,碾压混凝土的干缩呈直线降低,且抗磨性和抗冻融能力明显提高; ( 3 )粉煤灰能有效提高碾压混凝土的耐久性,且在试验条件下的最佳掺量为30 % 。 |
