“…Thus, the successful usage of agricultural wastes, as a substitute for normal aggregates, contributes to the preservation of depleting resources which is non-renewable, decreases utilization of energy, and also decreases the expenses of construction materials. Authors has utilized a few scrap matters in concrete, with recycled aggregate, fly ash, silica fume waste elastic tire, and GGBFS and waste and glass plastics 8 , 9 . Moreover, tobacco wastes, coconut shell (CS), rice husk ash, palm shell, pistachio shell, oil palm shell (OPS), utilized to deliver lightweight aggregate concrete.…”

Today, it’s getting harder to find natural resources for concrete production. Utilization of the waste materials not just helps in getting them used in concrete, cement, and other construction materials, but also has various secondary advantages, for example, saving in energy, decrease in landfill cost, and protecting climate from pollution. Considering this in the development of modern structural design, utilizing waste materials instead of natural aggregate is a good option to make concrete that is sustainable and eco-friendly. The present research aims to find the impact of adding glass fiber into sustainable concrete made with silica fume, as a partial replacement of cement, and coconut shell added with different ratios as a replacement of coarse aggregate, on concrete mechanical and durability aspects. Various blends were made, with coconut shell as a substitution of coarse aggregates with different ratios. Portland cement was substituted with silica fume at 5%, 10%, 15%, and 20% by cement weight in all concrete blends. The volume ratios of glass fibers utilized in this study were 0.5%, 1.0%, 1.5% and 2.0%. Adding glass fibers increases concrete density to some extent and then marginally reduces the density of coconut shell concrete. When the percentage of glass fibers increases, the compressive, flexural and split tensile strength of coconut shell concrete also increases. From the lab results and SEM images of the present research display that glass fibers might be utilized in coconut shell concrete to enhance its mechanical and durability attributes, to accomplish sustainable concrete with acceptable strength with ease.

“…The concave part of CS is smooth, which results in the good workability of CS concrete. Higher impact and abrasion resistance in CS aggregate have been reported in comparison with conventional coarse aggregate 15 . Olanipekun et al 16 reported that an increased content of CS coarse aggregate reduced the cost of concrete mix but slightly reduced the compressive strength.…”

This study investigated the effect of adding fly ash on the mechanical and durability characteristics of coconut shell (CS) concrete. Two different mixes were developed, one with CS and the other with conventional aggregate and CS as coarse aggregate. Cement was replaced with Class F fly ash in terms of weight at 0, 10, 20, and 30% in both mixes. Test result showed that the CS concrete with 10% fly ash replacement level exhibited the highest compressive and tensile strength. The addition of fly ash decreased the porosity of CS concrete due to its fineness and increased hydration products in the matrix at later ages. Additionally, it also improved the weak aggregate interfacial transition zone of CS lightweight concrete. Thus, the fly ash addition in CS concrete showed lower values of water absorption, permeable voids, sorptivity, and chloride permeability. Furthermore, the increasing content of fly ash addition improved the durability characteristics of CS concrete considerably.

“…The split tensile strength of SCC2 was increased up to 17 % by the addition of sisal fiber. It can be noticed that the addition of sisal fiber increases the tensile strength up to 8% and this may be attributed by bridging mechanism of fiber (Prakash, 2020).…”

This paper investigates the effect of sisal fiber addition on fresh ,mechanical properties of self compacting concrete(SCC) and flexural performance of fiber reinforced RC beams made with mineral admixtures like Meta Kaolin (MK) and Fly Ash (FA)which is an industrial waste. The mixes were prepared by varying MK content from 5% to 15% with 5% increment with constant fly ash content of 30%. The results reveal that increasing the content of MK beyond 10% leads to reduction in strength. And also the negative influence of MK and fiber addition on workability performance was overcome by the addition of FA, super plasticizer and viscosity modifying agent (VMA). Based on the test results it is evidenced that FA and MK make use of mineral admixture in the production of SCC. It also clarifies that the addition of sisal fiber improves mechanical properties of concrete. The research work shows that the ultimate load of fiber reinforced RC beams was raised when compared to normal RC beams. The flexural toughness and ductility of concrete was found to increase appreciably when sisal fiber was added.
