“…Comparing the values presented on Table 7 with the values presented by expanded clay aggregates and basalt aggregates (specific mass equal to 2.95 g/cm 3 ), the calcined clay samples of this research present intermediary values of specific mass 3 . The compressive strength test utilized to characterize the calcined aggregates is based on the compressive strength test for cylindrical specimens of concrete 15 .…”

“…Preliminary analysis indicate the viability of utilizing calcined clay lightweight aggregate as building material, despite the high level of water absorption. Furthermore, the calcined clay lightweight aggregates show promising compatible characteristics relative to structural concrete [3][4][5][6] . However, to produce calcined clay lightweight aggregates with specific characteristics, such as low water absorption or high compressive strength, the production process requires adaption.…”

This paper aims to study the influence of including wood sawdust and sodium silicate in the production process of calcined clay lightweight ceramics. In the production process first, a sample used by a company that produces ceramic products in Brazil was collected. The sample was analysed by techniques of liquidity (LL) and plasticity (LP) limits, particle size analysis, specific mass, X-ray diffraction (XRD) and X ray fluorescence spectrometry (XRF). From the clay, specimens of pure clay and mixtures with wood sawdust (10%, 20% and 30% by mass) and sodium silicate were produced and fired at a temperature of 900 o C. These specimens were submitted to tests of water absorption, porosity, specific mass and compressive strength. Results of this research indicate that the incorporation of wood sawdust and sodium silicate in the ceramic paste specimens can be useful to make calcined clay lightweight ceramics with special characteristics (low values of water absorption and specific mass and high values of compressive strength), which could be used to produce calcined clay lightweight aggregates to be used in structural concrete.

“…Para a presente pesquisa, foram confeccionados corpos de prova de concreto cilíndricos, com 100 mm de diâmetro e 200 mm de altura, utilizando-se agregados leves de argila calcinada proveniente de Itu/SP e Porto Ferreira/SP, agregados leves de argila expandida e agregados convencionais de basalto (SANTIS, 2012 Conhecendo-se as características de cada um dos agregados, procurouse manter em um mesmo patamar os consumos de cimento para os quatro tipos de concreto, assim como a relação água/cimento de 0,5 e o volume dos agregados miúdos e graúdos para todas as dosagens, como ilustra a Tabela 2. Os concretos foram secos no ambiente do laboratório por 24 horas.…”

“…A substituição dos agregados graúdos convencionais por agregados leves proporciona a produção de concretos leves, com massa específica menor que a dos concretos convencionais, gerando uma economia nas fundações e em fôrmas e cimbramentos, com a possibilidade de aplicação em diversas áreas da construção civil, como em edificações pré-fabricadas, pontes e plataformas marítimas (SANTIS, 2012).…”

Este trabalho tem por objetivo a avaliação da durabilidade de concretos estruturais com agregados leves inovadores, utilizando a metodologia de carbonatação acelerada. Tal metodologia foi definida, inicialmente, considerando as etapas de moldagem, cura e preparação dos corpos de prova de concreto de cimento Portland, assim como as condições de exposição (idade, tempo de exposição, teor de CO 2 , temperatura e umidade relativa). Para avaliação e validação da metodologia, foram analisados concretos com agregados convencionais (basalto), agregados leves comercias (argila expandida) e dois tipos de agregados leves inovadores (argila vermelha calcinada), produzidos especificamente para o presente estudo. Os resultados desta pesquisa indicam que a metodologia de carbonatação acelerada escolhida foi eficaz na identificação da influência dos agregados leves inovadores na velocidade da frente de carbonatação em concretos estruturais.

“…From Brazil, Ruy Santos, manager of Interfilmes, asked De Santis to write and direct an adaptation of Jorge Amado's novel Seara Vermelha/Red Field (1946), another story of immigrants set in the Sertão desert. Interfilmes had already secured the necessary funds from some Brazilian investors; De Santis showed interest in the project but eventually declined (Santos 1954a(Santos , 1954b(Santos , 1954c. Another offer came from Poland, where Rome 11:00 and Days of Love were huge box office hits.…”

The ‘De Santis case’: Screenwriting, political boycott and archival research

The 'De santis case': screenwriting, political boycott and archival research absTRacTIn the late 1940s and throughout the 1950s writer-director Giuseppe De Santis was the most successful Italian film-maker worldwide, thanks to box-office hits like the Oscar-nominated Riso amaro/Bitter Rice (1949). However, endless rows with producers, distributors and censorship soon forced him into professional exile until his creative voice was completely silenced. Over the years De Santis denounced a systematic boycott against him because of his social and political commitment. All scripts needed the central government film office approval; this system enforced a form of pre-emptive censorship by controlling the writing and packaging process. This article unveils the findings of comprehensive research conducted at the De Santis Fund in Rome. While De Santis's official filmography lists only one title in the last 33 years of his life, his archive contains dozens of treatments and full scripts (and the film-maker's correspondence) adding up to a total of almost 50 projects that were never made. The materials analysed here not only allow a thorough re-write of De Santis's career, but also shed light on the intricate relations between politics and the Italian film industry in the post-war years.
