High-performance, High-volume Fly Ash Concrete for Sustainable Development
For a variety of reasons, the concrete construction industry is not sustainable. First, it consumes huge quantities of virgin materials. Second, the principal binder in concrete is portland cement, the production of which is a major contributor to greenhouse gas emissions that are implicated in global warming and climate change. Third, many concrete structures suffer from lack of durability whi...
متن کاملRecyclability of Concrete Pavement Incorporating High Volume of Fly Ash
Recyclable concrete pavement was made from fly ash and crushed limestone sand and gravel as aggregates so that the concrete pavement could be recycled to raw materials for cement production. With the aim to use as much fly ash as possible for the sustainable development of society, while achieving adequate strength development, pavement concrete having a cement-replacement ratio of 40% by mass ...
متن کاملHigh Volume Fly Ash Concrete for Paver Blocks
Use of concrete paver blocks is becoming increasingly popular. They are used for paving of approaches, paths and parking areas including their application in pre-engineered buildings and pavements. This paper discusses the results of an experimental study conducted on Fly Ash Concrete with the aim to report its suitability for concrete paver blocks. In this study, the effect of varying proporti...
متن کاملDurability of High-performance Concrete with Fly Ash
High-performance concrete (HPC) is usually produced using high quality materials. These high quality constituents drastically increase the initial cost of HPC, hence hindering its more widespread use. Therefore, the main goal of this research project was to produce a low cost enhanced performance concrete or even a low cost HPC, using low quality fly ash and locally available crushed aggregates...
متن کاملSustainability, Performance and Mix Design of High Volume Fly Ash Concrete
Conventional concrete technology generates significant amounts of CO2, NOx and SOx (greenhouse gases linked with global warming) through the combustion of fossil fuels to process and transport concrete components as well as the calcination of limestone required to create portland cement. Furthermore, the mining and processing of conventional concrete components damages ecosystems and exhausts n...
