“…Above 0.25% fibre content, the lower strength values of BFRC compared with Plain concrete can be attributed to the large quantity of fibres/excessive fibre content in the concrete having an adverse effect on compressive strength. Similar results were observed by other researchers [7,9,10,[34][35][36][62][63][64] with Humphrey [7] noting that large quantity of fibres in the mortar produced voids and created nonuniform distribution within the composite, which led to reduced compressive strength.…”

“…Concrete is one of the most widely used material in the construction industry because it offers good strength and durability properties, and its primary constituents are readily available and cheap [1][2][3]. Despite its numerous advantages, concrete is also well known to have several weaknesses, such as a low tensile strength capacity that is significantly lower than its higher capacity to resist compressive loading, brittleness, low postcracking capability, and low fracture resistance [4][5][6][7][8][9][10].…”

“…Banana fibres are a good prospect because they can easily be extracted from banana pseudostems, which are otherwise often left to rot in plantations in form of an agricultural waste. Studies conducted on Banana fibres have indicated that they possess good performance properties, are environment friendly, are less expensive, and are readily available, and thus, it can be utilized to improve mechanical properties of concrete [9,10,14,20,[32][33][34][35]. However, studies carried out have majorly been concentrated on a single fibre length while investigating the fibre content [7,9,10,[34][35][36].…”

This experimental study aimed at investigating the impact of addition of banana fibres on the mechanical (compression, splitting tension, and flexure) and microstructural (microscopic morphology and Energy Dispersive X-ray Spectroscopy) properties of concrete. Concrete mixes comprising of banana fibres of varying fibre lengths (40, 50, and 60 mm) and fibre contents (0.1, 0.2, 1.0, 1.5, and 2.5%) were assessed. Addition of banana fibres to concrete was observed to significantly impact on compressive strength only at lower fibre contents of up to 0.25% for all fibre lengths. Fibre length had no significant impact on compressive strength at lower fibre contents of up to 0.25%, but shorter fibres were observed to perform better than longer ones at higher dosages more than 0.25%. Increase in fibre content positively impacted on tensile strength of concrete at relatively lower fibre dosages of up to 1%. Similarly, fibre length impacted on tensile strength of concrete at lower fibre contents of up to 1% and, longer fibres were observed to be more effective than shorter ones. Addition of banana fibres generally did not greatly contribute to flexural strength of concrete but had a marginal impact only when shorter fibres were used at lower fibre dosages. Also, microstructure of concrete was improved through better bonding between the fibres and the matrix and reduction in porosity of the matrix, which resulted in improved mechanical properties of the composite. Banana fibres further contributed to changes in phases of the composite structure of Banana fibre-reinforced concrete (BFRC) through a reduction in its interplanar spacing and lattice structure. For optimal purposes, addition of banana fibres should be limited to a maximum of 1% fibre content preferably using shorter fibre lengths. Further research to improve flexural strength of BFRC to meet minimum technical requirements is required before it can be considered for structural applications.

“…For that purpose, supplementary cementitious materials have been developed to replace part of the required cement [31]. These alternative materials include the reuse of waste such as fly ash, which can replace 15-30% of cement [32][33][34][35][36] and silica fume which replace cement by 5-25% [37,38]. There are other residues as well that have been used, such as ground granulated blast furnace slag [39], metakaolin [40,41], sewage sludge ash [42,43], rice husk ash [44], which can replace up to 20% of cement.…”

As important as it is, sustainability related with the concrete material is more than reducing the amount of cement in concrete mixes. In effect, there can be other types of contributions to a sustainable development using this fundamental material. The purpose of this book chapter is to analyse some of these approaches, in particular, concrete durability, reducing the amount of required concrete (and then cement) through innovative structural design, and reducing the amount of aggregates used in the concrete material. More specifically, examples and results obtained in Chile with biological self-healing concrete, thinner concrete pavements and concrete with industrial and domestic waste as partial aggregate replacement are included in the chapter. Due to its importance, the geo-dependency of the concrete material is addressed as well.
