| Summary, etc. |
Pervious concrete (PC) is receiving growing interest as a sustainable paving material <br/>due to its high permeability, making it ideal for stormwater management, reducing <br/>surface runoff, and enhancing groundwater recharge in urban environments. <br/>Incorporating construction and demolition waste (CDW) materials while <br/>manufacturing PC through replacing aggregates rather than disposal makes it a <br/>sustainable material with dual environmental benefits. However, the use of such <br/>recycling materials can influence the performance of PC, which is already characterized <br/>by relatively low mechanical strength. <br/>Therefore, it's crucial to carefully identify the properties of recycled aggregate <br/>pervious concrete (RA-PC) and the appropriate use of these properties. Contributing to <br/>this, the study focuses on the use of both recycled crushed clay brick (RCCB) and <br/>recycled crushed concrete (RCC) as waste materials replacing both coarse and fine <br/>aggregates in pervious concrete (PC). The quality of both parent materials was relatively <br/>high compared to those obtained from old demolition waste. Since they were selected not <br/>only upon their availability as waste materials, but also upon their quality. <br/>A total of eighteen mixtures were prepared over two consecutive stages with eight <br/>mixtures were fully developed using recycled crushed clay brick (RCCB) in stage 1 and <br/>nine mixtures were fully developed using recycled crushed concrete (RCC) in stage 2 in <br/>addition to control mixture in each stage. The coarse and fine aggregates were totally <br/>replaced for both type to maximize the benefits of consuming more recycled waste, since <br/>the RA represents 70.0% of total volume of mixture constituents. Additional two control <br/>mixtures developed using natural aggregates (NA) were included for comparison. <br/>Through the developed mixtures different parameters were investigated, particularly <br/>replacing NA with RCCB and RCC, changing coarse to fine ratio (C/F) while <br/>maintaining total aggregate volume, increasing aggregate size, lowering cement content <br/>Changing aggregate to binder A/B ratio), the use of supplementary cementitious <br/>materials (SCMs), such as silica fume and metakaolin, with different percentages, and <br/>lowering the strength level of the parent concrete from which RCC was derived. <br/>A set of experimental tests were carried out to evaluate the dry density, porosity, and <br/>absorption, as well as the mechanical performance of recycled crushed clay brick <br/>pervious concrete (RCCB-PC) and recycled crushed concrete pervious concrete (RCC-<br/>PC), including compressive strength, splitting strength, flexural strength. Durability was <br/>assessed through abrasion and impact resistance. Additionally, hydrological performance <br/>was examined through infiltration test, clogging behavior and the effect of maintenance. <br/>These investigations collectively reveal that, compared to natural aggregates, the <br/>inherently higher porosity, higher irregularity and angularity of RCCB the resulting <br/>pervious concrete exhibits increased total porosity, reduced dry density, enhanced <br/>infiltration rate, greater absorption capacity, and improved resistance to clogging. With <br/>the fact that these benefits come at the expense of reduced mechanical properties. <br/> Whereas, mixtures incorporated RCC exhibited reduced porosity than conventional <br/>PC resulted in higher dry density, slight reduction in infiltration rate, modest reductions <br/>in mechanical strengths, and reduced clogging resistance. Furthermore, the mechanical <br/>properties of RCCB-PC or RCC-PC can be improved along with acceptable hydrological <br/>properties through adding more fine and cementitious content, or SCMs. |

لقد حظي استخدام الركام المعاد تدويره، باهتمام كبير في صناعة الخرسانة في السنوات الأخيرة في إطار السعي نحو ممارسات أكثر استدامة. وفي هذا السياق، تناولت هذه الدراسة خصائص الخرسانة المُنفذة المكونة بالكامل من الركام المعاد تدويره المستخرج من الطوب الطفلي المعاد تدويره والخرسانة المعاد تدويرها. تم إعداد تسعة عشر خلطة مختلفة مع عدة متغيرات متنوعة: نوع الركام المستخدم، نسبة الركام الخشن إلى الناعم (0.9/0.1 , 0.95/0.05 , 0.85/0.15)، وعدد من المواد الأسمنتية المضافة (غبار السيليكا والميتاكاولين بنسب مختلفة) كنسبة إستبدال من وزن الأسمنت. شملت الخصائص التي تم مناقشتها خلال هذه الدراسة: مقاومة الضغط، مقاومة الشد بالانفلاق، مقاومة الانحناء، مقاومة الصدم بطريقتين مختلفتين، مقاومة الإحتكاك، الكثافة ، نسبة الفراغات ،نسبة الإمتصاص ، والنفاذية. كما تم تقييم تأثير دورات الانسداد على نفاذية الخلطات قيد الدراسة، وكما تم أيضا اقتراح بعض أساليب الصيانة وتطبيقها. وأخيرًا، تم تقييم الطاقة الكامنة في نوعي الركام المعاد تدويرهما مقارنةً بالركام الطبيعي. وقد أشارت نتائج هذه الدراسة إلى الإمكانيات الواعدة للركام المعاد تدويره - سواء الناتج من الطوب الطفلى المعاد تدويره أو الخرسانة المعاد تدويرها - في إنتاج الخرسانة المُنفذة المستدامة. |
