外加剂-粉煤灰-煤矸石基胶凝材料初探

Brief on admixture-fly ash-gangue base binding material

研究了外加剂-粉煤灰-煤矸石基胶凝材料(简称AFG胶凝材料)的基本性能,对其水化产物和机理进行了初步探讨。结果表明:AFG胶凝材料的早期强度低,但后期强度发展较快,且其强度随着粉煤灰掺量的增加而下降。AFG胶凝材料的主要水化产物是水化硅酸钙和水化铝酸钙等。

On the basic properties of additive - fly ash - gangue based cementing materials （hereinafter referred to AFG cementing material） , the hydration products and their mechanism has been discussed. The results show that： the early intensity of AFG cementing materials is low, but the intensity of the latter part of the development becomes faster, and with the strength of the fly ash content increased, the intensity of AFG drops . The main hydration products of AFG cementing materials are hydrated calcium silicate, and hydrated calcium aluminate etc.
