项目摘要

Masonry buildings and masonry constructions can be traced back centuries ago. Loadbearing structural elements of masonry use concrete masonry blocks which are then filled with masonry grout materials which contain a large amount of Portland cement (PC) and natural sand (NS). PC is not an environmentally friendly material since the production of PC is responsible for about 8% of the total CO2 and other greenhouse gases (GHG). Hence, the primary goal of this research is to develop environmentally friendly masonry grout materials that will use limited or no PC. Industrial waste (slag), construction wastes (ground recycled concrete masonry), and clay soil will be used to replace PC. Use of NS in masonry grout materials and in traditional concrete materials has resulted in the depletion of stone reserves. Stones are crushed to produce NS and then they are hauled long-distances to construction sites. This long-distance hauling for the NS results in more emissions of GHG into the environment. Hence, this research will also investigate the use of locally available construction and demolition wastes as the substitute for NS for use in masonry grouts. These wastes are generated by concrete block manufacturers and demolition of old concrete structures which end up in the landfills causing environmental and health hazards to people living nearby. Thus, this research will also help in alleviating the landfill problem and minimizing the health and safety hazards. The newly developed environmentally sustainable grout materials will be then tested to evaluate their ability to perform the structural functions required of masonry grouts. A large number of masonry prism specimens and several tall masonry wall specimens will be built and tested in the structural testing lab at the University of Windsor. Additionally, computer simulations will be undertaken to determine various critical information needed for the assessment of the grout materials in loadbearing applications. This research will be completed in five years and seven engineering students will execute the work under the supervision of Dr. S. Das and Dr. B. Banting. These highly trained and skilled students will be able to bridge the skills gap in Canada.
砖石建筑和砖石建筑可以追溯到几个世纪前。砌体的承重结构元件使用混凝土砌体块,然后用含有大量波特兰水泥(PC)和天然砂(NS)的砌体灌浆材料填充。PC不是一种环保材料,因为PC的生产产生了约8%的二氧化碳和其他温室气体(GHG)。因此,本研究的主要目标是开发环境友好的砌体灌浆材料,将使用有限的或没有PC。用工业废料(矿渣)、建筑废料(再生混凝土砌块)、粘土代替PC。在砌筑灌浆材料和传统混凝土材料中使用NS导致石材储量枯竭。石头被压碎,产生NS,然后它们被长途运输到建筑工地。NS的这种长途运输导致更多的温室气体排放到环境中。因此,本研究还将调查使用当地可用的建筑和拆除废物作为替代NS用于砌体灌浆。这些废物是由混凝土砖制造商及拆卸旧混凝土构筑物所产生,最后弃置于堆填区,对附近居民的环境及健康构成危害。因此,这项研究也将有助于缓解垃圾填埋问题,并将健康和安全危害降至最低。新开发的环境可持续灌浆材料将进行测试,以评估其执行砌体灌浆所需的结构功能的能力。在温莎大学的结构试验室将建造大量的砌体棱柱体试件和几个高大的砌体墙试件并进行试验。此外,将进行计算机模拟,以确定评估承重应用中灌浆材料所需的各种关键信息。这项研究将在五年内完成,七名工程专业的学生将在S。达斯和B博士班廷这些训练有素、技术精湛的学生将能够弥补加拿大的技能差距。
