Resumo: | Light weight masonry mortars containing vermiculite are commonly used when one wants thermal and acoustic insulation. This Thesis investigated the incorporation of recycled used tires rubber crumbs as light weight mortar aggregates, in substitution of parts of vermiculite and sand. The main objective was based on the natural resources protection and decrease in environment impact, by means of the recycling in large quantities, of a problematic dischargeable product (used tires). By means of the pertinent standards, six masonry mortar compositions were investigated; two compositions of light weight masonry mortars containing cement, lime, sand and vermiculite, two compositions containing cement, lime, sand, vermiculite and rubber crumbs from recycled tires. In addition, to have a broader comparative ground ,a traditional mortar (cement+slime+sand) and an industrialized mortar (cemet+lime+sand+additives), not of the light weight class, were also investigated. The substitution of parts of vermiculite and sand by rubber recycled aggregates was taken to 45wt% of the whole light weight mortar mass. The results showed that the incorporation of rubber aggregates, promoted a decrease in the mortar drying shrinkage, a reasonable increase in the compressive strength and an expressive increase in the adherence strength of the light mortars. Another positive factor was that the inclusion of the rubber aggregates did not caused any sensible alteration neither in the thermal conductivity nor on the acoustic absorption, comparatively to the values presented by the light mortars without rubber aggregates. It was concluded that the light weight mortars containing recycled rubber aggregates, constitute a viable new contribution to the sustainable constructive elements field, fulfilling this Thesis main objective. |

Esta Tese teve como objetivo principal, a incorporação de agregados de borracha reciclada de pneus em argamassas leves, substituindo partes de vermiculita e areia. Com isso, visou-se a proteção de recursos naturais e diminuição de impacto ambiental, através da reciclagem em quantidade apreciável, de um produto de descarte muito complexo (pneus usados). Usando-se a normalização pertinente, foram investigadas seis composições: dois traços de argamassa leve utilizando-se cimento, cal, areia e vermiculita expandida; dois traços de argamassa leve contendo cimento, cal, areia, vermiculita expandida e agregados de borracha reciclada de pneus. Para mostrar diferenças marcantes, também foram investigadas, um traço da argamassa tradicional densa (cimento:cal:areia) e uma argamassa industrializada densa (cimento:cal:areia+aditivos especiais). A substituição de partes da vermiculita e da areia por agregados de borracha reciclada de pneus foi levada até 45% em massa desses agregados, na composição global da argamassa leve. Os resultados mostram que a inclusão dos mesmos, diminuiu a retração, promoveu um aumento razoável da resistência à compressão e um aumento acentuado na resistência de aderência das argamassas leves. Outro fator positivo foi que a presença de agregados de borracha não promoveu alteração na condutividade térmica e nem na absorção acústica, comparativamente aos níveis dessas propriedades essenciais, apresentados pelas argamassas leves sem os agregados reciclados. Os resultados permitem concluir, que as argamassas leves, contendo agregados de borracha reciclada de pneus substituindo partes da areia e da vermiculita, caracterizam uma contribuição nova na área de elementos construtivos sustentáveis, indicando viabilidade de emprego na construção civil, atendendo às exigências da normalização e cumprindo o objetivo alvo desta Tese.Financiadora de Estudos e Projetosapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMUFSCarBRArgamassaVermiculitaBorracha reciclada de pneusRevestimentosENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICAArgamassa para revestimento com propriedades termoacústicas, produzida a partir de vermiculita expandida e borracha reciclada de pneusMasonry mortar with thermo-acustic insulating properies based on vermiculite and recicled rubber aggregates from wasted tiresinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesis-1-1c3f093c1-80a8-4311-a505-df4d7db98b43info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL5809.pdfapplication/pdf13474238https://repositorio.ufscar.br/bitstream/ufscar/718/1/5809.pdf8b51135cdfa96a63f90435eb49b9c72dMD51TEXT5809.pdf.txt5809.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/718/2/5809.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD52THUMBNAIL5809.pdf.jpg5809.pdf.jpgIM Thumbnailimage/jpeg6306https://repositorio.ufscar.br/bitstream/ufscar/718/3/5809.pdf.jpg8057b0c7d200b3c963977cc1487e2d58MD53ufscar/7182023-09-18 18:31:27.941oai:repositorio.ufscar.br:ufscar/718Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:27Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
