Recycled Construction(再生建筑)研究综述
Recycled Construction 再生建筑 - Recycled Construction and Demolition (C&D) materials have been considered as alternative materials in different civil engineering applications, such as unbound pavement layers and structural embankments, in which geosynthetics are also frequently applied. [1] Recycled construction and demolition (C&D) waste can reduce the rebuild cost, and is environmentally friendly when recycled asphalt pavement (RAP) aggregate constitutes the main part. [2] In the construction industry, the efficient use of recycled construction and demolition waste (CDW) as aggregates in structural concrete and the implications of that practice for a sustainable flow of materials are contributing to the establishment of a circular economy. [3] This research reports the development of a Novel Alkali-Activated Unfired Brick (NAAUB) using clay filter cake (CFC) waste produced during the washing of recycled construction and demolition materials. [4] Use of aggregates from recycled construction and demolition wastes in concretes alleviates the disposal problem and reduces the cost of concrete significantly. [5] The creep deformation characteristics of recycled construction and demolition waste (CDW) filler are important factors affecting its road performance. [6] Geosynthetic-reinforced soil structures have been used extensively in recent decades due to their significant advantages over more conventional earth retaining structures, including the cost-effectiveness, reduced construction time, and possibility of using locally-available lower quality soils and/or waste materials, such as recycled construction and demolition (C&D) wastes. [7] This study aims to evaluate the CO 2 uptake capacity in rendering mortars produced with recycled construction and demolition waste (CDW) by natural carbonation. [8] The secondary goal of this study was to investigate the stress-strain response of pavements with aggregate base courses made of three types of recycled construction and demolition wastes, being recycled concrete aggregate (RCA), crushed brick (CB), and waste excavation rock (WR). [9] Despite the advances observed over the last decade, Brazil still suffers from the scarce use of recycled construction and demolition waste (RCDW). [10] This study investigates the potential of fine particles of recycled construction and demolition waste (CDW) aggregate to undergo alkali-activation when mixed with an appropriate alkaline solution. [11] This study aims to provide a comprehensive literature review pertaining to the possibilities of using recycled construction and demolition waste in composite manufacturing. [12] This paper describes an investigation on the performance of encased columns constructed on a very soft soil using different types of encasement (three woven geotextiles with different values of tensile stiffness) and different column fill materials (sand, gravel and recycled construction and demolition waste, RCDW). [13] Recycled construction and demolition (C&D) materials have recently gained attention as valuable resources and are widely applied in pavements, ground improvements, and engineered fills. [14] This paper focus on air jigging separation studies for removing brick particles from recycled construction and demolition waste aggregates. [15] Therefore, the recycled construction and demolition waste can significantly contribute to the sustainability of construction industry from technical, economic and environmental points of view. [16]回收的建筑和拆除 (C&D) 材料已被视为不同土木工程应用中的替代材料,例如未粘合的路面层和结构路堤,其中也经常使用土工合成材料。 [1] 回收的建筑和拆除 (C&D) 废物可以降低改造成本,并且在再生沥青路面 (RAP) 骨料构成主要部分时是环保的。 [2] 在建筑行业,有效利用回收的建筑和拆除废物 (CDW) 作为结构混凝土中的骨料,以及这种做法对可持续材料流动的影响,都有助于建立循环经济。 [3] 本研究报告了一种新型碱活化不烧砖 (NAAUB) 的开发,该砖使用在回收的建筑和拆除材料的洗涤过程中产生的粘土滤饼 (CFC) 废物。 [4] 在混凝土中使用回收的建筑和拆除废物中的骨料可以缓解处置问题并显着降低混凝土的成本。 [5] 再生建筑垃圾(CDW)填料的蠕变变形特性是影响其道路性能的重要因素。 [6] 近几十年来,土工合成材料加筋土结构已被广泛使用,因为它们比更传统的挡土结构具有显着优势,包括成本效益、缩短施工时间以及使用当地可获得的低质量土壤和/或废料的可能性,例如回收的建筑和拆除 (C&D) 废物。 [7] 本研究旨在评估通过自然碳化处理回收建筑和拆除废物 (CDW) 生产的砂浆对 CO 2 的吸收能力。 [8] 本研究的第二个目的是研究由三种类型的再生建筑和拆除废物组成的集料基层路面的应力-应变响应,即再生混凝土集料 (RCA)、碎砖 (CB) 和废弃开挖岩石。 WR)。 [9] 尽管在过去十年中观察到了进步,但巴西仍然受到再生建筑和拆除废物 (RCDW) 使用稀少的困扰。 [10] 本研究调查了再生建筑和拆除废物 (CDW) 骨料细颗粒与适当的碱性溶液混合时进行碱活化的潜力。 [11] 本研究旨在提供有关在复合材料制造中使用回收建筑和拆除废物的可能性的综合文献综述。 [12] 本文描述了使用不同类型的包裹物(三种具有不同拉伸刚度值的编织土工布)和不同的柱填充材料(沙子、砾石和回收的建筑和拆除废物、RCDW)在非常软的土壤上建造的包裹柱的性能调查。 )。 [13] 回收的建筑和拆除 (C&D) 材料最近作为宝贵的资源受到关注,并广泛应用于路面、地面改良和工程填料。 [14] 本文着重于空气跳汰分离研究从回收的建筑和拆除废物骨料中去除砖颗粒。 [15] 因此,从技术、经济和环境的角度来看,回收的建筑和拆除废物可以显着促进建筑业的可持续性。 [16]
recycled construction material 再生建筑材料
Based on three databases (Web of Science, Compendex and Scopus) and VOSviewer visualization software, this study conducts a bibliometric analysis of the literature in the field of recycled construction materials in pavement engineering. [1] The HME leaching concentrations from the GP mortars in non-acidic water environment were less than the HME leaching limits specified for recycled construction materials directly contacting with water, thus the GP materials with BA can be used in dry or non-acidic water environment. [2] Different layers of bio-based, recycled construction materials for the envelope were tested with respect to their efficacy in improving the energy performance of a case study building. [3] The push for environmental sustainability in the civil engineering industry has resulted in an increased interest in the use of recycled construction materials, with one example being the use of waste plastic for the modification of bituminous binder in asphalt mixtures. [4] Therefore, drinking water treatment sludge has been investigated and used as a recycled construction material owing to its properties similar to clay. [5] However, due to the ongoing depletion of natural limestone in cement production and aggregate in construction, this material may be used as a recycled construction material. [6] In addition, recycled aggregates produced from the concrete waste portion of the CDW were used to obtain 100% recycled construction material on the scale of the binder and aggregate phase. [7]本研究基于三个数据库(Web of Science、Compendex 和 Scopus)和 VOSviewer 可视化软件,对路面工程中再生建筑材料领域的文献进行文献计量分析。 [1] 非酸性水环境中 GP 砂浆的 HME 浸出浓度低于直接与水接触的再生建筑材料规定的 HME 浸出限值,因此具有 BA 的 GP 材料可用于干燥或非酸性水环境。 [2] 测试了用于围护结构的不同层的生物基可回收建筑材料在改善案例研究建筑的能源性能方面的功效。 [3] 土木工程行业对环境可持续性的推动导致对使用可回收建筑材料的兴趣增加,其中一个例子是使用废塑料来改性沥青混合物中的沥青粘合剂。 [4] 因此,由于其与粘土相似的性质,饮用水处理污泥已被研究并用作可回收的建筑材料。 [5] 然而,由于水泥生产和建筑骨料中天然石灰石的持续消耗,这种材料可用作再生建筑材料。 [6] 此外,从 CDW 的混凝土废料部分生产的再生骨料被用于获得 100% 的再生建筑材料,其规模为粘合剂和骨料相。 [7]

Crushed brick aggregate (CBA), reclaimed pavement waste, recycled construction waste, treated soil are some major non-conventional materials used for pavement construction purposes (Abbas et al. [1] Furthermore, this paper analyses the destruction mode of construction waste particles and reveals the destruction mechanism of recycled construction waste mixtures. [2] In order to study the long-term deformation characteristics of recycled construction waste filler, a series of laboratory tests and field measurement have been carried out. [3] To investigate the effect of freeze-thaw cycle on the mechanical and porosity properties of the recycled construction waste mixtures, a series of freeze-thaw cycles, cyclic loading and unloading and CT scan tests were carried out on four proportions of samples, including the brick, concrete and mortar slag. [4]碎砖骨料 (CBA)、再生路面废料、再生建筑废料、处理过的土壤是用于路面施工目的的一些主要非常规材料 (Abbas et al. [1] 此外,本文分析了建筑垃圾颗粒的破坏方式,揭示了再生建筑垃圾混合料的破坏机理。 [2] 为研究再生建筑垃圾填料的长期变形特性,开展了一系列室内试验和现场测量。 [3] 为了研究冻融循环对再生建筑垃圾混合物力学和孔隙率性能的影响,对砖块等四种比例的样品进行了一系列冻融循环、循环加载和卸载以及 CT 扫描测试。 、混凝土和砂浆渣。 [4]
