Abstract
Resumo: Este trabalho focalizou as propriedades pozolânicas de residuos de cerâmica vermelha (RCV), suas relacoes com a composicao das materias-primas utilizadas nas industrias (massas cerâmicas) e a temperatura de queima, com vistas ao aproveitamento dos RCV como produto cimenticio. A reatividade pozolânica obtida pelo Ensaio Chapelle e a composicao quimica de amostras representativas do polo cerâmico paulista de Panorama mostraram resultados promissores para o aproveitamento desses residuos como adicao mineral em cimentos e concretos. Constatou-se que o RCV podera constituir uma nova fonte de material pozolânico para a industria do cimento, que apresenta demanda emergente por adicoes minerais que agreguem, alem de beneficios tecnicos nos seus produtos, maior sustentabilidade a sua cadeia produtiva.

Atualmente, os residuos da industria de cerâmica vermelha apresentam-se como uma alternativa em potencial para uso em matrizes cimenticias como adicao mineral ou pozolana de baixa reatividade. Este estudo, teve como objetivo avaliar a influencia da substituicao parcial do cimento CP V ARI por residuo da industria de cerâmica vermelha em placas de fibrocimento. O cimento foi substituido em volume nas percentagens de 0, 15, 25 e 50%. Essas combinacoes foram reforcadas com fibras de celulose e poli...

Red ceramics, due to the low compressive strength and high porosity, make it difficult to use it as an artificial aggregate in the production of mortars and concretes. However, since it has a silicon-rich composition, the ceramic material from blocks and tiles has been studied as a possible supplementary cementitious material in concrete and also as a raw material in alkali-activated binders. This paper aims to evaluate the content of calcium hydroxide (portlandite) fixed in the alkali activatio...

O objetivo desta pesquisa foi avaliar a reducao da alcalinidade de compositos cimento-madeira, produzido com cimento Portland e particulas residuais de Pinus spp., em funcao da substituicao gradual do cimento Portland pelas pozolanas silica ativa (SA) metacaulim (MK), cinza volante (CV), escoria de alto-forno (EAF), cinza de casca de arroz (CCA) e residuo de cerâmica calcinada (RCC). Para tanto, foram produzidos corpos de prova cilindricos, com diâmetro de 5 cm, com compositos com 100% de ciment...

A crescente geracao de residuos resulta em uma intensa preocupacao quanto a disposicao final destes materiais. Os advindos da industria de cerâmica vermelha despertaram o interesse para o uso em argamassas e concretos, pois, devido a sua composicao, sao capazes de gerar reacao pozolânica. Neste trabalho, foram realizados testes com os residuos coletados em tres empresas (A, B e C) da regiao sul de Santa Catarina, caracterizando- os e, posteriormente, produzindo argamassas com 10% de substituicao...

Abstract The objective of this paper is to study some characteristics of a component to buildings made with gypsum plaster (commercial – CGP and recycled – RGP), and wastes (red ceramic – RC and porcelain – PW) by loading-pressure. Bricks were prepared with a solid mass composition containing 50% (by weight) of binder, 50% (by weight) of waste, and very small water/dried powder ratio (0.22). Specimens were molded with uniaxial loading-pressure (10 kN) before setting times. Compressive and flexur...

Studies about the reactive potentiality of the Red Ceramic Waste (RCW) and of the rice husk ash (RHA) and their use in the composition of Portland cement, avoiding inadequate disposal, is a theme of strong relevance for the environmental sustainability of the productive chain of a country. Analysis of the feasibility of incorporating RCW and RHA to Portland cement demands studies involving the effects on compressive strength and, overall, about the performance of the hydrated matrix when suscept...

The red-clay waste (RCW) derives from blocks and bricks in their production process and also in the construction industry, when these materials are used in vertical walls. When originated in the production process, the RCW presents a lower degree of impurities, while when originated from construction sites, it contains a greater degree of impurities due to being stored with other residues before its disposal. According to the Brazilian Environmental Council (CONAMA) in its Resolution 307, RCW re...
