“…Mixing use fresh water consumption: Water usually constitutes 15%–20% of fresh concrete by volume. Either potable water or recycled waste water can be used, but this analysis considered only potable water because recycled water always contains adverse contaminants (Gupta et al, 2021; Mane et al, 2019), and their removal greatly complicates the environmental analysis. The energy involved in obtaining potable water for batching is used for pumping and in its chemical treatment.Fly ash production and processing: Fly ash is mostly unburnt siliceous particulates released in the exhaust gas when coal is burned in power plants to produce electricity (Shobeiri et al, 2021).…”

“…Replacing natural aggregates with recycled ones (Hafez et al, 2020a; Yu et al, 2021), fines from stone crushing (Rajput, 2018; Salehi et al, 2021), excavated material with the soil extracted (Priyadharshini et al, 2018) have all been tested with some success. Using treated waste water (Gupta et al, 2021; Mane et al, 2019) is an obvious idea. And blast furnace slag has also been proposed (Piemonti et al, 2021; Rahla et al, 2019) as an environment-friendly component for fabricating structural members.…”

Due to the constituted ingredients are both rich in reserves, seawater sea-sand self-compacting concrete (SWSS-SCC) today has been treated as an ideal material in constructing island and coastal structures. The technique feasibility of applying SWSS-SCC in real engineering has been recognized by investigating the material properties, but its environmental impacts (EIs) has rarely been concerned at current stage. Under such a background, a refined life cycle assessment model of SWSS-SCC was developed in this study based on the China’s latest production data. Life cycle phases considered include extracting and preparing raw materials, component material production, mixing concrete and transportation occurred in the whole processes. After verifying the model, the impacts of several factors like concrete curing method, fly ash incorporation content, sea-sand transportation distance and electricity generation approach, which have never been investigated before, on the energy cost and carbon dioxide equivalent emissions generated in manufacturing SWSS-SCC were discussed. The simulated results showed that: (a) Using seawater and sea-sand slightly increases the concrete’s compressive and tensile strengths. Replacing some cement with fly ash notably decreases the early-age strengths, but curing at 60°C can offset that effect. (b) Replacing fresh water and natural sand by sea-water and sand in Humen Town decreases the production EIs of SWSS-SCC. For this concrete, cement production and raw material transportation are the main contributors to the overall EIs. (c) During producing SWSS-SCC, using electricity generated from clean fuels can effectively reduce the system’s EI, but changing fuel used to fire the cement kiln has little effect. (d) High temperature curing to increase the fly ash content is not environmentally sound. Reducing the mixture’s water to binder ratio is more benefit for incorporating fly ash. (e) From an environmental evaluation view, applying SWSS-SCC is more ecological in island constructions than coastal buildings.

“…One of the major issues in the construction sector is to develop sustainable concrete to reduce the emission carbon dioxide (CO 2 ) and other pollutants during the manufacturing process. The cement manufacturing process is complex as well as it emits a lot of pollutants in the environment along with the utilization of large amounts of energy leaving back more and more carbon footprints [3,4]. tanks was studied [11].…”

Partial replacement of cement with non-polluting materials is to be done to balance the performance and cost. Dumping the waste materials will affect the environment directly [5,6]. Some of the researchers have tried to modify concrete by utilizing the cow dung ash (CDA) in the past few years, the approach is considered to enhance the concrete durability as well as considering the environmental issues [7,8]. Aliabado et al. 2014 studied on reusing or recycling waste material in concrete [9]. It has been suggested that cow dung may also improve workability, act as additional binder, has more hardening enzymes and adhesive qualities [9,10]. The durability of the mixes was found to be enhanced as well as the binding capacity is found to be improved due to the enhancement in the lateritic soil plasticity. The application of cow dung with respect to concrete
