“…Hence it enhances the life of concrete structure [17,18]. The improvement shown in the strength and concrete durability with the addition of FA and RHA along with cement [2,19]. The reason behind the triple blend concrete is, it improved the microstructure of concrete due to different particle size create dense particle packing.…”

“…The average particle size at D10 were found that 8 m for ordinary Portland cement, 1 m for type-1 RHA, 2 m for type-2 RHA, 4 m for type-3 RHA and 5 m for FA particles. The previous study on cement paste [23] and mortar [19] was reported that the particle packing increased the strength and durability of triple blend concrete than control concrete. The present research is aimed to produce sustainable and durable triple blend concrete by using FA and RHA along with OPC.…”

The assessment of environmental impact on concrete is an important aspect for its durability. The use of supplementary cementitious materials (SCMs) in the concrete can be enhanced the durability. This makes concrete sustainable and reduced environmental issues. In this research paper illustrate the experimental study on the performance of triple blend concrete made up of fly ash (FA) and rice husk ash (RHA) along with ordinary Portland cement (OPC). The current research the concrete composition was used as 20, 30 and 40% cement replacement by FA and RHA. The durability properties such as ultrasonic pulse velocity (UPV), electrical resistivity (ER), water absorption and carbonation depth of triple blend concrete were determined, and for microstructure performance formation factor and Scanning Electron Microscope (SEM) were performed. The improvement in durability was observed up to 40% replacement of cement. The durability of concrete improves with increase in formation factor. The SEM images proved the improvement in particle packing of concrete.

The microbial self-healing concrete has been a new technology to repair cracks, the former study showed that the precipitated CaCO3 could fill the cracks and reduce the permeability coefficient of cracks. This paper presents the effect on strength parameters with the addition of bacillus subtilis bacteria and calcium lactate. This study helps to improve the strength of self-repairing concrete with the use of bacillus subtilis bacteria and calcium lactate. The production of calcium carbonate in bacterial concrete is limited to the calcium content in cement. Hence calcium lactate is externally added to be an additional source of calcium in the concrete. The influence of this addition on compressive strength and modulus of rupture are highlighted in this study. The Bacillus subtilis bacteria and calcium lactate are mixed in concrete with different concentrations and tested for compressive and modulus of rupture of concrete. The results show that the performance of concrete improves with the addition of bacillus subtilis bacteria and calcium lactate into concrete.

“…Besides, the reduced micro-voids along the ITZ results in the high fracture toughness of the siliceous FA-based concrete [23]. Additionally, the FA-based concrete possesses better chloride penetration resistance than OPC concrete and an increased electrical resistivity [25]. The most concerning matter of the FA-based concrete is the low strength development rate at an early age due to a low reactivity [25]; but it can gain strength over a long period.…”

Performance of Sustainable Green Concrete Incorporated With Fly Ash, Rice Husk Ash, and Stone Dust

et al. 2021

The performance of a sustainable green concrete with fly ash (FA), rice husk ash (RHA), and stone dust (SD) as a partial replacement of cement and sand was experimentally explored. FA and RHA have a high silica content, are highly pozzolanic in nature and have a high surface area without any treatment. These by-products show filler effects, which enhance concrete’s density. Results showed that the FA and RHA materials have good hydration behaviour and effectively develop strength at an early age of concrete. SD acts as a stress transferring medium within concrete, thereby allowing the concrete to be stronger in compression, and bending. Consequently, water absorption capacity of the sustainable concrete was lower than that of the ordinary one. However, a little reduction in strength was observed after the replacement of the binder and aggregate using the FA, RHA and SD, but the reduction was insignificant. The reinforced structure with sustainable concrete containing the FA, RHA, and SD generally fails in concrete crushing tests initiated by flexural cracking followed by shear cracks. The sustainable concrete could be categorized as a perfect material with no significant conciliation in strength properties and can be applied to design under-reinforced elements for a low-to-moderate service load.
