  • Phosphate rock waste in the production of cement tile
    Mariana Pires, Rayanne de Jesus Andrade Fidelis, Domingos Sávio de Resende, Augusto Cesar da Silva Bezerra
    Results in Engineering, 2022
    One of the main concerns of the mining industry is the large amount of waste generated in mineral extraction and processing. Besides causing environmental impacts, these environmental liabilities occupy extensive areas and can lead to problems in their disposal. The use of such waste in civil construction has shown promise through several research. This paper proposes the incorporation of waste rock (WR) from a phosphate mine in the production of cement tiles as a partial replacement for Portland cement. Physical and chemical tests characterized the WR. The cement tiles were developed with the replacement of cement by WR with a content of 25% at temperatures of 400 °C and 600 °C. Hydraulic tiles were developed by replacing cement with WR at a content of 25%. The pieces were produced with WR without heat treatment and treated at temperatures of 400 °C and 600 °C. The tiles were evaluated according to some parameters, such as visual and dimensional analysis, water absorption, acid attack, and strength. As a result, all tiles presented strength above 3.5 MPa, within limits required by the standard. The tiles calcined at 600 °C showed the best pigmentation. The heat treatment did not influence the strength, although it helped in the pigmentation process. Therefore, it was possible to obtain cement tiles pigmented using mine waste with reduced Portland cement consumption, adequate strength, and aesthetically suitable.

    Cleaner Engineering and Technology, 2022
    The ceramic industry consumes a large amount of raw materials, much of which consists of fluxes. In view of the growing demand for infrastructure and sanitation, the waste valorization is a viable alternative for recycling materials, mitigating the extraction of natural resources. In this context, the present work studied the feasibility of replacing feldspathic flux by ceramic sludge waste (CS) in the sanitary ware production. The waste was characterized by particle size distribution, chemical composition, and mineralogical phases. The replacement ratios (by mass) were set in a wide range of 5, 10, 25, 50, 75, and 100%. The ceramic mass in fluid aspect was evaluated by means of density, viscosity, thixotropic index, setting rate and drying time. The hardened state was investigated through shrinkage, pyroplastic deformation, compressive and flexural strengths, water absorption and microstructure. The results showed that CS can be a stronger flux than granite. One of the proportions with total replacement (B-100) showed promising results, being the best option in terms of rheological behavior and physical-mechanical properties. An important finding concerns water absorption, which decreases with increasing the CS content. It is suggested that CS valorization on industrial scale may be sufficient to eliminate the entire volume of waste. This approach represents an eco-friendly solution, promotes the closing of waste loops and can be a way to cleaner production in the sanitary ware industry.

    This study characterized discarded sanitary ware waste (SWW) that could not meet quality requirements. To understand the composition of such SWW, samples were collected, processed, and characterized. This SWW was used to substitute granite in ceramic slips, and the final recycled sanitary ware compositions of 5%, 10%, 25%, 50% and 100% were obtained. Then, the mixtures were evaluated based on density, rheology, linear shrinkage, water absorption, and flexural strength. The results for viscosity and pyroplastic deformation in specimens containing the ceramic waste were better than the reference slip used in a production line. Results for density, water absorption and linear shrinkage showed no significant difference from the control samples. Although the replacement of more than 5% of granite reduced the flexural strength, no tested specimen was below the minimum value required by the industry.

    The manufacture of Portland cement used in the production of concrete emits large amounts of CO2into the atmosphere, contributing to the increase of the greenhouse effect. The environmental impact generated by the mineral exploration activity is a problem of easy verification, especially in open pit mines. The present work evaluated the possibility of using iron ore tailing as an addition to the partial replacement of the cement in mortars. The iron ore tailings were processed by drying in oven (48h at 105oC) and milling in a planetary mill (10min at 300RPM), obtaining medium grain size of 14,13 μm. For the characterization, laser granulometry, X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential thermal and thermogravimetric analysis (DTA / TGA) were performed. The sample is composed predominantly by quartz, hematite, goethite and gibbsite. After the characterization, the waste was used in the preparation of test specimens, with 10, 20 and 30% weight substitution of the cement. The composites were submitted to compression tests, with ages of 3, 7 and 28 days, using a strength rate of 0,25MPa/s. The mortars with 10, 20 and 30% of substitution presented resistance of 41.65, 36.26 and 31.64 MPa, being able to be characterized as category of Portland cement of resistance 40, 32 and 25 respectively. Considering the reduction of cement in the mortars produced, the results of compressive strength were relevant for the substitutions. The cements produced with the substitutions according to the Brazilian standards under the mechanical aspect can be classified as Portland cement.

    This paper presents an experimental evaluation of how variations in proposed parameters interfere with compressive strength resistance of mortar and concrete specimens. The results were obtained through laboratory tests in which samples were tested under varying conditions. These conditions were as follows: speed of load application (0.25, 0.50, 0.75, and 1.00 MPa/s), environmental conditions (saturated, 2 h dried, and 24 h dried specimens), curing (dry and wet), and specimen ends preparation (sulphur, neoprene, rectification, and without regularization). Comparisons were made on the basis of the compression strength resistance results and the coefficient of variation in order to analyse the homogeneity and dispersion among variables. It was found that in the case of capping, the best results were obtained by the rectification of concrete specimens. In the case of loading speed, the best results were obtained at a speed of 1 MPa/s. Dry curing showed the best results, even though not resulting in the highest resistance. The results for specimen conditions were in accordance with the expectations, with lower dispersion for saturated specimens.

    The work presents the characterization of clays from sterile mining of the concentrated phosphatic materials of Araxa in Minas Gerais as pozzolanic materials. Three clays of distinct tones, namely, yellow (YC), red (RC), and intermediate (IC) clays, were used at different levels of excavation depth. The clays were calcined at three temperatures (680, 760, and 840 °C) in a muffle-type electric oven. The pozzolanic activity levels of the calcined clays was measured through the conductivity change in saturated Ca(OH)2 solutions and also from the result of the compressive failure load achieved by mortars with 35% of the Portland cement replaced with the calcined material. The results indicated that the calcined clays showed a high level of pozzolanic activity and can be used as a partial substitute for Portland cement, thus suggesting the possibility of recovering this sterile material.

    Materials Science Forum, 2014
    The Alto Paranaiba and Triângulo Mineiro mesoregion in the state of Minas Gerais and the State of São Paulo have a number of industries with eucalyptus chip fired boilers that produce great amounts of ash. Since thermoelectric ashes generally have good pozzolanic activity, this paper studied the mechanical behavior of cementitious composites made with raw eucalyptus chip ash as a partial replacement for Portland cement and processed under two different conditions. The mechanical behavior of the composites was measured from tests on specimens for their compressive strength, tensile strength to diametral stress and to bending. Results show ashes could be used as mineral additives.

    O grande volume de resíduos sólidos industriais gerados pela indústria de batatas pré-fritas e o alto custo do seu manejo estimulam pesquisas em busca de soluções mais adequadas para a sua destinação final. Esse trabalho caracterizou o resíduo sólido (lodo) de Estação de Tratamento de Efluentes (ETE) de indústria de batatas. O lodo foi processado através de secagem, desidratação, moagem e peneiramento. Para a caracterização do lodo foram utilizadas técnicas de granulometria a laser, microscopia eletrônica de varredura (MEV) com espectrômetro de raios X dispersivo em energia (EDS), difração de raio X, análise térmica diferencial (DTA), termogravimétrica (TGA) e perda ao fogo. Após a caracterização, o lodo foi utilizado para a confecção de compósitos cimentícios, em substituição parcial do cimento, em massa equivalente para substituição do mesmo volume, determinado pelas massas específicas de ambos materiais, nas porcentagens de 3, 5, 7 e 10%. Os compósitos foram ensaiados para a obtenção da resistência à compressão e do módulo de elasticidade dinâmico. A utilização do lodo de ETE como pozolana foi descartada, tendo-se como base o resultado do ensaio de perda ao fogo. Nos ensaios mecânicos realizados, nota-se que a adição de lodo, em substituição parcial ao cimento, impactou, negativamente, de forma mais relevante a resistência à compressão. Tais ensaios foram considerados satisfatórios para os compósitos com substituição do cimento por 3% e 5% de lodo.
