摘要

摘要如今，在混凝土生产中使用废弃材料对于清洁环境和降低混凝土成本至关重要。本研究旨在利用整体防水（IWP）掺合料和废陶瓷作为细粒细骨料来提高混凝土的某些力学性能，以提高抗压强度、弹性模量和吸收率。研究表明，仅使用IWP可提高抗压强度和弹性模量，同时减少吸收，并使用陶瓷粉末代替普通砂可获得更多优势，即抗压强度从41.7提高到47.8 MPa，弹性模量从25.22增加到29.61 GPa。吸收率下降到只有1%，而没有陶瓷废料的混凝土的吸收率为1.96%。本研究还研究了抗硫酸盐侵蚀的耐久性。

Waste ceramic as partial replacement for sand in integral waterproof concrete: The durability against sulfate attack of certain properties

Abstract Nowadays, the use of waste materials in concrete production is crucial for a clean environment and less concrete cost. This study aimed to enhance some mechanical properties of concrete utilizing integral waterproof (IWP) admixture and using waste ceramics as fine aggregate with finer particles to improve compressive strength and modulus of elasticity and absorption studied. Studies indicate increase in compressive strength and modulus of elasticity by using IWP only and also a reduction in absorption and by using ceramic powder as a replacement with normal sand, more advantages were achieved, i.e., the compressive strength increased from 41.7 to 47.8 MPa by replacing sand with some ceramic waste, and the modulus of elasticity increased from 25.22 to 29.61 GPa. The absorption lowered to only 1% while it was 1.96% for concrete without ceramic waste. Durability against sulfate attack was also studied in this research.
