Abstract

To bring an challenging and acceptable change in construction industry, upcoming graduates have to be much aware of alternate materials to be used in conventional concrete with improved performances and this study can be an encouraging approach to them. Many research studies have investigated the possible use of industrial by-products such as fly ash from thermal power plants, red mud from aluminium manufacturing industry, copper slag from copper smelting industry, GGBS from steel industry, and waste foundry sand from metal casting industries in cement concrete production. Here, it is investigated on the possibility of utilizing two industrial by-products in the production of concrete for achieving sustainable development. Metakaolin is used for replacing a specific percentage of cement, and waste marble powder and waste foundry sand are used to replace different percentages of conventional fine aggregates (sand) for producing a sustainable concrete. It is observed from the results that properties of cement concrete are influenced by the percentage content of metakaolin, waste marble powder and waste foundry sand.

大理石粉和铸造废砂作为细集料对偏高岭土水泥混凝土性能的影响研究

为了给建筑行业带来具有挑战性和可接受性的变化，即将毕业的学生必须对可用于传统混凝土的替代材料有更多的了解，并提高其性能。许多研究调查了在水泥混凝土生产中使用工业副产品的可能性，如火力发电厂的粉煤灰、铝制造业的赤泥、铜冶炼业的铜渣、钢铁业的 GGBS 以及金属铸造业的废铸造砂。在此，我们研究了在混凝土生产中利用两种工业副产品以实现可持续发展的可能性。使用偏高岭土替代特定比例的水泥，使用废大理石粉和废铸造砂替代不同比例的传统细集料（砂），以生产可持续混凝土。研究结果表明，水泥混凝土的性能受偏高岭土、废大理石粉和废铸造砂含量百分比的影响。
