通过CaO、NaOH、NaAlO2和Na2SiO3激发淤泥焚烧灰化学活性后与水泥复合作为胶凝材料制备生态透水砖,通过正交试验研究了不同化学激发剂对水泥净浆抗压强度的影响,探究了骨胶比对淤泥焚烧灰制备的生态透水砖劈裂抗拉强度、渗透性、抗冻性及保水性的影响。结果表明:复合化学激发剂可以改善淤泥焚烧灰制备的生态透水砖的力学性能,但将降低淤泥焚烧灰制备的生态透水砖的透水性、保水性。骨胶比与透水砖的透水系数呈正相关,当骨胶比从3.0增大到3.4时,未掺淤泥焚烧灰的对照组透水系数增大了153%,掺淤泥焚烧灰的试验组透水系数增大了184%。为满足工程要求,淤泥焚烧灰的掺量不宜超过30%。

In view of developing novel alloys for applications in supercritical water-cooled reactor fuel cladding and in-core components, a 12%Cr reduced activation ferrite/martensite(RAFM) steel with good corrosion resistance and irradiation performance was developed. V and Ta were added to form fine MX type carbonitrides and enhance the high temperature creep rupture strength. Microstructure stability of the steel during long-term aging at 650 C was studied experimentally combined with the simulation of ThermoCalc and DICTRA software. The results show that the precipitates in the steel during long-term aging contain M23C6, MX and Laves phase. M23C6 carbides play a major role in the stabilization of the tempered martensite lath structure by exerting a large Zener pinning force as compared with MX and Laves *** V and Ta in the steel can not only promote MX precipitation, but also refine M23C6 carbides and thus improve the thermal stability of lath/subgrains, which is beneficial to the improvement of high temperature microstructure stability of the 12%Cr RAFM steel.
