| 摘 要： | 采用X射线衍射试验(XRD)研究了掺加橡胶颗粒的水泥净浆水化产物的物相结构.结果表明:(1)水泥净浆的抗压强度随橡胶颗粒掺量的增加而降低;(2)尽管水泥的化学成分复杂,但掺入橡胶颗粒后,在其水化产物中并没有发现新的物相结构;(3)掺加橡胶颗粒的水泥净浆的水化产物中氢氧化钙(CH)晶体的衍射峰强度显著降低,原因之一可能是...

| Abstract: | Phase structure of the blends of cement paste incorporating crumb rubber is investigated using X-ray diffraction(XRD).The results show that:(1) Compressive strength of the hardened cement paste is reduced as the content of crumb rubber increases;(2) Although the chemical constituents of cement is complicated,no new phase is found in the hydration products of the cement paste incorporating crumb rubber;and(3) The peak intensity of calcium hydroxide(CH) from the hydration products of the cement paste incorpor... |
