| 进一步分析还表明，水化产物与纤维素醚的吸附能力与水泥水化的延迟具有对应关系：吸附越强，延迟越明显，不过钙矾石对纤维素醚的吸附较弱，但它的形成却受到明显延迟。 Further analysis also shows that the adsorption capacity of hydration products and cellulose ether corresponds to the delay of cement hydration: the stronger the adsorption, the more obvious the delay, but the weak adsorption of cellulose ether by ettringite, but the formation of cellulose ether is obviously delayed. 纤维素醚对硅酸三钙及其水化产物有强烈的吸附，因而明显延迟硅酸盐相水化，对钙矾石的吸附较低，但钙矾石的形成却被明显延迟，这是因为钙矾石形成的延迟是受溶液中Ca2+平衡的影响，这是纤维素醚延迟硅酸盐水化的延续。 Cellulose ether has a strong adsorption on tricalcium silicate and its hydration products, thus significantly delaying the hydration of silicate phase and the adsorption of ettringite is lower, but the formation of ettringite is significantly delayed, because the formation delay of ettringite is affected by the balance of Ca2+ in solution, which is the continuation of delayed hydration of silicate by cellulose ether. 。 |
