摘要

Sodium metasilicate pentahydrate (SMP), a type of hardening-accelerator, was widely used in cement slurry to enhance its early strength. In this study, we found that SMP had an novel ability to adjust the compatibility between 2-Acrylamido-2-Methyl Propane Sulfonic Acid (AMPS)-based Fluid Loss Additive (FLA) and Retarder in oil well cement. Reasons for this significance were proposed, that SMP promoted the formation and growth of hydration products by accelerating the hydration velocity of cement slurry, which increased the adsorption sites of cement hydration products. As that happens, the more AMPS based polymers were adsorbed simultaneously on the surface of the hydration product, thereby effectively improving the compatibility problem caused by the competitive adsorption between the admixtures. Meanwhile, while SMP speeded up the hydration reaction, the pores space of cement hydrated particles were filled with more hydrates and consequently altered its pore size distribution, whose action was also beneficial to the development of early strength. Overall, those findings will provide further interpretation for the effect of admixture on cement hydration products and offer some useful references for practical application of oil well cementing in the future.
