“…Rao et al [13] studied the deterioration and the relative sulphate resistance of HPC in severe sulphate environments and suggested using Fly ash (FA) by partially replacing natural pozzolana for enhanced performance. Present authors also have investigated the effect of fly ash, metakaolin, and silica fume based composite fiber-reinforced HPC on strength and durability properties and concluded the viability of using fly ash, metakaolin, silica fume, and composite fibers in CFRHPC production for enhanced strength and durability properties [14][15][16]. The widespread application of FA and MK in the construction industry is the result of extensive investigations on the use of FA and MK in concrete during the past two decades [17][18][19][20][21][22].…”

Improvements in concrete properties have been achieved by researchers with the invention of High-Performance-Concrete (HPC), which can now be improvised by using a combination of mineral admixtures. HPC is usually more brittle which can be made ductile by modifying its composition by adding fibers in the design mix, which led to the development of fiber-reinforced concrete. High-Performance-Concrete made with glass fibers and polypropylene fibers is regarded as Composite Fibre (Glass and polypropylene) Reinforced High Performance Concrete (CFRHPC). The development of cost-effective state-of-the-art procedures for producing, evaluating, and designing with CFRHPC will enhance the performance for each performance characteristic and can be reliably achieved in the field. This investigation evaluates the effect of cement being partially replaced by combined fly ash and metakaolin with glass fibers and polypropylene fibers as an addition to produce high-performance concrete with composite fiber for resistance to hydrochloric acid, magnesium sulphate, and sulphuric acid attack for 30, 60, and 90 days. The water to binder ratios (W/B) of 0.275, 0.300, 0.325, and 0.350 and an aggregate to binder ratio (A/B) of 1.75 were adopted. Fly ash and metakaolin were replaced in the range from 0% to 15% each, glass fibers were added in volume percentages from 0% to 1%, and polypropylene fibers were kept constant at 0.25%. The combined effect of fly ash and metakaolin at 5% each as replacement of cement and the addition of composite fiber dosage of glass fiber=1% and polypropylene fibers=0.25% for W/B of 0.275 was found to be the optimum combination to obtain maximum acid attack resistance, which was also justified by SEM, EDX, and XRD analysis done in this investigation. CFRHPC production minimizes enormous cement production and safeguards the environment from pollution and concrete from environmental pollution throughout its service life.

“…The incorporation of 0.25, 0.5 and 0.75% PP fibres reduced the fluidity by 2.8, 5.55 and 8.33%, respectively. Patil and Patil [38] incorporated 1.5% PP fibres (length 12 or 20 mm), by volume, into Class F FA-based concretes activated with NaOH and sodium silicate solution. The results showed lower workability with including PP fibres.…”

Recently, the inclusion of different types of fibres into geopolymers, as reinforcement, has amplified due to the rapid increase in geopolymers developments. In spite of geopolymers have prospective properties such as low carbon footprint, low consumption of energy, good compressive strength, resistance to fire, resistance to flame, resistance to corrosion and good durability, they undergo from low tensile strength and flexural strength. To avoid these shortages, different types of fibres could be incorporated into geopolymers to enhance their toughness, tensile strength and ductility. The current survey aims to review the effect of different types of fibres named polypropylene (PP), polyvinyl alcohol (PVA), carbon and glass fibres on the fresh and hardened properties of geopolymers.

“…

Concrete, the most widely used construction material in the present industry, consumes large quantities of cement and aggregates. The large amount of concrete is being consumed due to urbanization and its increasing demand globally, and that results in the development of high performance concrete and high strength concrete [1]. Cement is the most frequently utilized building ingredient in construction engineering.

The influence of metakaolin (MK) on concrete was investigated as a partial replacement of cement, which is liable for high content of CO2 emission during the manufacturing process. The study aimed to assess the compressive strength, temperature performance and drying shrinkage of MK blended concrete. Different ratios of MK (5%, 10%, and 15%) as cement replacement, and two ratios of superplasticizer (SP), 1.5%, and 2% as cement weight were utilized in this study. The results indicated that using MK increased the compressive strength at 28¬ day. The improvement of strength is ascribed to the pozzolanic reaction and the packing effect of fine MK particles. MK blended concrete experienced a decrease in the temperature rise of heat of hydration (HOH) and low drying shrinkage when compared to the control concrete. The SP ratio does not have significant effect on the temperature of the concrete mixtures: however, using 1.5% SP slightly reduces the drying shrinkage of MK blended concrete compared to 2% SP. In conclusion, Incorporation of MK as partial cement substitute enhances the concrete strength, thus various types of concrete can be produced. Low temperature and drying shrinkage of MK blended concrete help in reducing thermal crack after casting process.
