“…LP addition affects the pore structure of the cement paste. It is reported that LP addition linearly increases the size of capillary pores (20-40 nm) and due to the high silica content, RHA is said to be an extremely reactive pozzolana (Pipilikaki and Beazi-Katsioti 2009;Xu et al 2015;Park et al 2016). Up to 20% of the cement may potentially be substituted by LP (or other fillers) to economize on the usage of OPC clinker and to reduce the energy/deleterious emissions associated with its production (Irassar 2009).…”

Industrial wastes and recycled materials are being utilized in the construction industry for preserving the environment, saving of materials, and enhancing durability of the construction material. Blending of cement with supplementary cementitious materials like fly ash, rice husk ash, and silica fume makes concrete more durable. The main objective of this study is to make use of the rice husk ash and lime powder (LP) as a replacement of Portland pozzolana cement considering various replacement levels. The engineering and durability performance in concrete with LP were performed through compressive strength and void measurement. The microstructure in the concrete with LP was characterized through XRD, SEM/EDS, and TG/DTA. Optimum replacement ratio for rice husk ash and LP were obtained through pozzolanic reaction based CSH formation.

“…In this direction, several scientists studied the influences of RHA in the composition of a composite binder on hydration processes, microstructural features and the composition and microstructure of the ITZ between the cement matrix and aggregate [10,52]. During experimental studies, researchers revealed that the cement paste, including RHA, had a smaller quantity of calcium hydroxide because of the pozzolanic reaction [53]. Accordingly, the porosity and the content of portlandite in the ITZ are reduced in the composite; due to this, the width of this zone between the cement paste and the aggregate is also reduced [54,55].…”

In the last few decades, the demand for cement production increased and caused a massive ecological issue by emitting 8% of the global CO2, as the making of 1 ton of ordinary Portland cement (OPC) emits almost a single ton of CO2. Significant air pollution and damage to human health are associated with the construction and cement industries. Consequently, environmentalists and governments have ordered to strongly control emission rates by using other ecofriendly supplemental cementing materials. Rice husk is a cultivated by-product material, obtained from the rice plant in enormous quantities. With no beneficial use, it is an organic waste material that causes dumping issues. Rice husk has a high silica content that makes it appropriate for use in OPC; burning it generates a high pozzolanic reactive rice husk ash (RHA) for renewable cement-based recyclable material. Using cost-effective and commonly obtainable RHA as mineral fillers in concrete brings plentiful advantages to the technical characteristics of concrete and to ensure a clean environment. With RHA, concrete composites that are robust, highly resistant to aggressive environments, sustainable and economically feasible can be produced. However, the production of sustainable and greener concrete composites also has become a key concern in the construction industries internationally. This article reviews the source, clean production, pozzolanic activity and chemical composition of RHA. This literature review also provides critical reviews on the properties, hardening conditions and behaviors of RHA-based concrete composites, in addition to summarizing the research recent findings, to ultimately produce complete insights into the possible applications of RHA as raw building materials for producing greener concrete composites—all towards industrializing ecofriendly buildings.

“…Neste contexto, verifica-se o desenvolvimento de diferentes pesquisas com a utilização do CCA em formulações de concreto e argamassa (Habeeb & Mahmud, 2010;Zain, et al, 2011;Van, et al, 2013;Salazar-carreno, Garcia-caceres & Ortizrodriguez, 2015;Park, Kwon & Wang, 2016;Vigneshwari, Arunachalam & Angayarkanni, 2018;Sharma & Sharma, 2018;Hu, He & Zhang, 2020). No Brasil, a literatura baila as pesquisas desenvolvidas em Santa Catarina (SC), São Paulo e RS (Tiboni, 2007).…”

Nos últimos anos, a ocorrência prematura da perda das características funcionais e estruturais das edificações, bem como consideráveis impactos ambientais devido ao processo produtivo do cimento levou ao desenvolvimento e adoção de materiais suplementares à composição do cimento Portland para aumentar a vida de serviço das estruturas e redução de impactos ambientais. Nesta temática, as pesquisas com o uso da cinza de casca de arroz (CCA) em argamassas e concretos (substituindo parcialmente o cimento Portland) vêm crescendo, gerando dessa forma grandes vantagens no campo técnico e ambiental. Diante disso, o presente trabalho apresenta um revisão sobre a utilização do resíduo agro-industrial de CCA na construção civil. A pesquisa foi desenvolvida a partir de uma revisão bibliográfica sistemática a respeito do assunto, passando por uma abordagem geral, apresentando a origem, dados estatísticos, aplicações e características tecnológicas sobre o tema.
