Within the scope of this study, blended cement pastes were prepared by replacing different proportions of ordinary Portland cement with ceramic waste powder (CWP). The hardened blended cement pastes were cured under tap water for different periods of time up to 180 days. Physico‐mechanical properties of specimens were studied in terms of free lime content, chemically combined water, compressive strength, and particle size distribution. The results manifested that the optimum content of ceramic waste which gave a marked improvement in the mechanical properties was 10% as compared to the other specimens at the same curing age. Besides that, similar specimens of the hardened blended cement paste containing 10% CWP were impregnated with unsaturated polyester and exposed to different doses of gamma rays from 10 to 50 kGy. Both the impregnated specimens that irradiated at a dose of 30 kGy and the neat blended cement paste that contained 10% ceramic waste were soaked in 1, 3, and 5% magnesium sulfate, sodium chloride solutions, and in seawater for up to 180 days. The results indicated that the composite specimens became more resistant to aggressive solutions and their durability increased as compared to the neat blended cement paste prepared under the same previous conditions.

含陶瓷废粉的辐照掺混水泥浆复合材料对硫酸盐，氯化物和海水侵蚀的性能

在本研究的范围内，通过用陶瓷废粉（CWP）替代不同比例的普通硅酸盐水泥来制备水泥浆。硬化的混合水泥浆在自来水中固化长达180天的不同时间。从游离石灰含量，化学结合水，抗压强度和粒度分布方面研究了样品的物理机械性能。结果表明，与相同固化时间下的其他样品相比，可显着改善机械性能的陶瓷废料的最佳含量为10％。除此之外，将含10％CWP的硬化混合水泥浆的类似样品浸入不饱和聚酯中，并暴露于10至50 kGy的不同剂量的伽马射线中。将以30 kGy剂量辐照的浸渍样品和包含10％陶瓷废料的纯净掺混水泥浆都浸入1、3和5％硫酸镁，氯化钠溶液中，并在海水中浸泡180天。结果表明，与在相同的先前条件下制备的纯净掺合水泥浆相比，复合材料标本对侵蚀性溶液的耐受性更高，并且耐久性得到提高。J.乙烯基添加物。TECHNOL。，26：24–34，2020.©2019塑料工程师协会 结果表明，与在相同的先前条件下制备的纯净掺合水泥浆相比，复合材料标本对侵蚀性溶液的耐受性更高，并且耐久性得到提高。J.乙烯基添加物。TECHNOL。，26：24–34，2020.©2019塑料工程师协会 结果表明，与在相同的先前条件下制备的纯净掺合水泥浆相比，复合材料标本对侵蚀性溶液的耐受性更高，并且耐久性得到提高。J.乙烯基添加物。TECHNOL。，26：24–34，2020.©2019塑料工程师协会
