“…Despite the great interest in polymer composites usage in construction, concrete is still the main building material. For this material, there has been a significant amount of research from involvement of modifications to the use of glass fiber as well [ 39 , 40 , 41 ]. Compared to non-modified concrete, glass fiber modified concrete showed better results in mechanical performance and properties as reported by Sanjeev and Sai Nitesh [ 42 ].…”

The progressive increase in the amount of glass waste produced each year in the world made it necessary to start the search for new recycling methods. This work summarizes the experimental results of the study on mortar samples containing dispersed reinforcement in the form of glass fibers, fully made from melted glass waste (bottles). Mortar mixes were prepared according to a new, laboratory-calculated recipe containing glass fibers, granite as aggregate, polycarboxylate-based deflocculant and Portland cement (52.5 MPa). This experimental work involved three different contents (600, 1200, and 1800 g/m3) of recycled glass fibers. After 28 days, the mechanical properties such as compressive, flexural, and split tensile strength were characterized. Furthermore, the modulus of elasticity and Poisson coefficient were determined. The initial and final setting times, porosity, and pH of the blends were measured. Images of optical microscopy (OM) were taken. The addition of glass fibers improves the properties of mortar. The highest values of mechanical properties were obtained for concrete with the addition of 1800 g/m3 of glass fibers (31.5% increase in compressive strength, 29.9% increase in flexural strength, and 97.6% increase in split tensile strength compared to base sample).

“…Also, the concrete industry is the highest consumer of natural aggregate and fresh water [3,4]. The higher production of concrete for future usage will lead to significant depletion of these natural resources and contamination of the environment [5,6]. Therefore, the need to have green concrete is essential so as to meet future demands of concrete while conserving natural resources.…”

So much innovations have ensued in the concrete industry in the last decade, especially in terms of ensuring concrete sustainability and its green initiatives. A call for sustainability is imminent in the industry as the production of ordinary Portland cement (OPC) which is the main binder of concrete contributes about 8% to the world's human-induced carbon dioxide emission. In addition, the production of concrete has posed a huge threat on natural deposits of raw materials. With billions of tons of concrete expected to be produced in the coming years to meet our infrastructure demand, it is critical for other alternatives to be considered for concrete production. Such alternatives mostly fit as partial or total replacement of OPC and aggregates. This paper explored the sustainable advantage of alkali-activated binders, supplementary cementitious materials, and recycled materials as raw materials in concrete. This short review has shown that it is possible to achieve a greener concrete with enhanced properties compared to the conventional concrete with the use of new materials. Also, on the ground of economic importance, the new materials were found to have better performance than the conventional ones.

“…As can be seen in Figures 3 and 4, the compressive strength and the split-tensile strength of the concrete, respectively increased with increasing curing age. This shows that there was rapid hydration of the concrete matrix, and more to this could be as a result of linking crack boundaries by basalt fibres (Anandaraj, Rooby, Awoyera, & Gobinath, 2018), which enhances the ductility of the concrete. The concrete strength development was totally influenced by the hydration rate and fibre linkages.…”
