Delays in construction are a widespread global problem, leading to potential cost overruns and legal disputes. Additionally, delays can result in a decline in construction quality and loss of public trust. The aim of this study is to examine the effects of project delays in various regions and the preventive role of optimizing concrete works. Literature review and bibliometric analysis are carried out to determine global research trends. Findings show that optimizing concrete works can provide benefits such as cost savings, time savings, improved quality and safety, and environmental benefits. Optimization of concrete material composition is one of the most examined topics in this field. Based on the findings, construction firms have the potential to attain cost efficiencies while concurrently mitigating carbon emissions.

“…The readers are redirected to various research documents to know more about the standard codes of practice of the testing procedures which are referred but not exclusively reported in this paper. In order to provide justifiable inputs into the nature of concrete mixtures having different combinations of RPMs, the suitability of visual evidences was evaluated first on the basis of an expected parent-material influence (PMI) [22,48]. The results from the scanning electron microscope (SEM) analysis is used to assess internal faults such air gaps, porous structure, and density of concrete, as well as the particle size of pozzolanic or micron level material.…”

“…The durability results are found to be more effective when binary composite coatings are applied based on the electrochemically rewarding metallic compounds [45][46][47]. There also exist potential challenges from dissolved ions as indicated by the ion penetration and diffusive mass transfer [48][49][50]. Even though the corrosion studies deals only with the surface chemistry, the resulting changes can be efficiently demarcated by morphological studies [37][38]49].…”

Recyclable Pozzolanic materials (RPM) derived from wastes are increasingly used in mortar and concrete for a number of purposes, chief among them being the reduction of cement quantity, which lowers construction costs as well as carbon footprint. Among these, the most often used mixture ingredients in concrete are fly ash (FA), rice husk ash (RHA), palm oil fuel ash (POFA), granulated slag (GS), silica fume (SF), construction debris waste powder (CDW), and calcined clay (CC). Recent studies reveal that they are reasonable to impart mechanical strength when applied individually; however, their combined effects are not extensively investigated due to the characteristic conflicts existing in their elemental composition and the resulting pozzolanic activities. We present a comprehensive evaluation of durability and strength properties of different combinations of binary and ternary replacements of specific pozzolanic components in varying amounts (5%, 10%, 15%, and 20%). These combinations were so chosen as to provide a compensatory effect on the apparent binding properties based on the difference in their geometry and composition. The results indicate that 5% of the ternary combination had good corrosion resistance and durability, whereas 10% of the single mode, 5% of the binary mode, and 5% of the ternary mode have high mechanical properties, durability, and resistance to corrosion. These insightful findings show that use of optimized mixtures of composite pozzolanic materials can improve the mechanical properties of concrete mixes by compensating each other for their intrinsic limitations, thereby ensuring higher sustainability towards green concrete applications.

“…are known for their elastic and thermal stability when used as insulation and envelope materials. The criticality of cement consumption in concrete production is found to be addressed partially, at least in mini-scale, by a careful replacement with various industrial and agro-based by-products [2][3][4][5]. Among these, though it is superficially beneficial to promote recycling of industrial by-products and waste products in construction, a broader approach can be visualized in the upcycling of agro-wastes because of their abundancy, low cost and large-scale positive environmental impacts.…”

The construction sector is actively adapting various measures such as use of green materials, optimization of design, activities and clean technology for the reuse of waste materials to reduce the environmental footprints. Among the green materials, replacement of concrete constituents has tremendous impact on the overall environmental benefits. The recycling of agro-waste fibres in concrete construction is comparatively less attempted due to the limitations in their applications. Present study focuses on comparative evaluation of proportioning coconut fibre and sisal fibre in concrete as singular and binary mixtures. The mechanical properties of the agro-waste fibre reinforced concrete in various proportions (from 0.5% to 2.5%) revealed a substantial increase in the compressive, tensile and flexural strength values. The binary mixture with a maximum value of 1.5% is found to be the best performing combination. The associated environmental impacts were identified using a two-step cause-evidence-impact methodology, suggesting the identification of critical steps in reducing environmental pollution and increasing the benefits.
