“…The inter-particulate space between the matrix (Al) and BSAP particles shrunk, which raised the dislocation pack. 27 Since BSAP contain high strength ceramic material which is SiO 2 , 33 it affects the CS of the composites positively. 27 The maximum compressive strength was found at 7.5 wt.% of BSAP introduced in the hybrid reinforced composite which was 308.32 MPa and this was 2.825 times the pure Aluminum.…”

Natural fiber composites offer a range of advantages, from biodegradability after the component’s lifespan little to no output of greenhouse gases and reduced pollution. These properties have made natural fiber composites popular in military, automotive, aerospace, and residential spaces. Bamboo Stem Ash Powder (BSAP) is one example of a commonly found natural fiber composite. This research looks into its effect on the physical and mechanical parameters when added to pure aluminum. The 0, 2.5, 5, 7.5, and 10 weight percent of BSAP were added in addition to the secondary reinforcements in the matrix. Parameters such as density, porosity, hardness, compressive strength, X-Ray Diffraction analysis results of BSAP/composite mixture, as well as Thermal Gravimetric Analysis (TGA) findings for the BSAP itself were all studied. The highest values of hardness 239.66 HV and compressive strength 308.32 MPa have been observed with 7.5 weight percent BSAP addition. It can be confirmed that these natural fiber composites can improve standard materials’ behavior when used correctly and can be potential candidates for many engineering applications.

“…According to the Food and Agriculture Organization, over 590 million tons of maize were produced worldwide at the beginning of the 21st century. 110 The United States is the largest maize producer, accounting for 43% of the world's production. CCA is the ash resulting from burning corncobs.…”

“…The increase in the use of bamboo leads to the possibility of applying waste generated in its production process in new materials. Although many studies consider bamboo for structural reinforcement of concretes, only a few report the use of bamboo ashes, particularly bamboo leaf ash (BLA), as a replacement for cement, probably due to the wide diversity of bamboo species. Umoh et al showed that replacing OPC with up to 15 wt % BLA attained up to 90% strength of OPC based mortar.…”

Toward Self-Healing Concrete Infrastructure: Review of Experiments and Simulations across Scales

et al. 2023

Cement and concrete are vital materials used to construct durable habitats and infrastructure that withstand natural and human-caused disasters. Still, concrete cracking imposes enormous repair costs on societies, and excessive cement consumption for repairs contributes to climate change. Therefore, the need for more durable cementitious materials, such as those with self-healing capabilities, has become more urgent. In this review, we present the functioning mechanisms of five different strategies for implementing self-healing capability into cement based materials: (1) autogenous self-healing from ordinary portland cement and supplementary cementitious materials and geopolymers in which defects and cracks are repaired through intrinsic carbonation and crystallization; (2) autonomous self-healing by (a) biomineralization wherein bacteria within the cement produce carbonates, silicates, or phosphates to heal damage, (b) polymer–cement composites in which autonomous self-healing occurs both within the polymer and at the polymer–cement interface, and (c) fibers that inhibit crack propagation, thus allowing autogenous healing mechanisms to be more effective. In all cases, we discuss the self-healing agent and synthesize the state of knowledge on the self-healing mechanism(s). In this review article, the state of computational modeling across nano- to macroscales developed based on experimental data is presented for each self-healing approach. We conclude the review by noting that, although autogenous reactions help repair small cracks, the most fruitful opportunities lay within design strategies for additional components that can migrate into cracks and initiate chemistries that retard crack propagation and generate repair of the cement matrix.

Carbon neutrality to limit global warming is an increasing challenge for all industries, particularly for the cement industry, due to the chemical emission of the process. For decades, reducing the clinker factor has been one of the main strategies to reduce the carbon footprint. Additional cuttings in the clinker content of cements seem possible with the upsurge of novel supplementary cementitious materials. This potential contribution represents only a fraction of the required carbon reductions for achieving the goal of carbon neutrality in the coming decades. This paper describes the current situation of the cement industry in Latin America and the Caribbean and the global opportunities and strategies to reduce the carbon footprint of cement and concrete and their adaptation to the regional conditions. Besides describing emerging supplementary cementitious materials, the potential contributions of industrialization and quality control are discussed. Moreover, limitations related to geography and standardization are analyzed. Regional considerations are made given the specific prospects of human development.
