水泥体系 meaning in English
cement system
Examples
- Influence on properties of cement system of water - reducer dosage
减水剂掺量对水泥体系性能的影响 - Study on early hydration in system of cement - coal stone by alternating current impedance spectroscopy
水泥体系早期水化的交流阻抗研究 - By measuring the temperature of the cement paste with the water - reducing agent , we discover that the water - reducing agent can retard the cement hydration
通过对减水剂-水泥体系水化温度的测定，得出减水剂能够抑制水泥水化。 - The influence of different gypsum on strengh of portland - sulphoalminate composite cement system is complicated , related with aluminiferouse mineral in cement system and the so4 ( superscript 2 - ) concentration of its hydrated solution ; in distilled water and maximum lime wash , the dissolution rate of dihydrate gypsum is higher than that of anhydrite but the dissolubility is lower
石膏品种对硅酸盐硫铝酸盐复合体系水泥强度的影响较复杂，与水泥体系中含铝矿物及其水化溶液中so4 (上标2 - )离子浓度有关；在蒸馏水和饱和石灰水中，二水石膏的溶解速度比硬石膏快，溶解度比硬石膏低。 - The modified copolymer solution has lower surface tension than the unmodified one . by measuring adsorptive content , we find that the adsorptive content of fdn superplasticizer is higher than the modified copolymers , but their adsorptive shape on the surface of the cement particles is different . measuring of potential of cement particle indicated that higher potential leads to better dispersibility for used superplasticizer
通过对减水剂的表面张力、吸附量、 5电位研究，发现改性后的减水剂均比未改性的共聚物更能降低水的表面张力；茶系减水剂比合成的减水剂具有更大的饱和吸附量，但彼此的在水泥颗粒表面的吸附形态并不相同：减水剂一水一水泥体系具有双电层，加了减水剂的水泥胶粒的电负性显著增加，改性后产物的负电性与改性前相比明显增加。
