A sustentabilidade de um edifício não baseia-se tão somente na análise global da sustentabilidade. É importante verificar a procedência dos materiais utilizados na obra, analisando a forma com que são produzidos e o impacto causado na produção. A certificação do bloco de solo-cimento-resíduo oferece uma análise pormenorizada do produto, mostrando seu ciclo de vida, a origem da matéria-prima e a gestão de resíduos. Por meio de uma revisão bibliográfica, foram identificadas as características do produto que preenchem os requisitos formais necessários para a certificação LEED V4. A grande quantidade de matéria-prima reaproveitada ou reciclada e de origem sustentável no bloco de solo-cimento-resíduo faz com que o material consiga grande pontuação em todos os requisitos exigidos para a concessão de certificação de Materiais e Recursos, atendendo a anseios dos produtores e consumidores finais. Abstract The sustainability of a building is not only based on the global analysis of sustainability. It is important to verify the origin of the materials used in the work, analyzing the way in which they are produced and the impact caused in the production. The certification of the soil-cement-waste block offers a detailed analysis of the product, showing its life cycle, raw material origin and waste management. Through a literature review, the characteristics of the product have been identified that meet the formal requirements required for LEED V4 certification. The large amount of raw material recycled or recycled and of sustainable origin in the soil-cement-waste block means that the material achieves a high score in all the requirements required for the certification of Materials and Resources, taking into account the desires of the producers and Consumers.

The study involved investigating the performance of ordinary Portland cement (OPC) stabilized soil blocks amended with sugarcane bagasse ash (SBA). Locally available soil was tested for its properties and characterized as clay of medium plasticity. This soil was stabilized using 4% and 10% OPC for manufacture of blocks of size 19 cm × 9 cm × 9 cm. The blocks were admixed with 4%, 6%, and 8% SBA by weight of dry soil during casting, with plain OPC stabilized blocks acting as control. All blocks were cast to one target density and water content followed by moist curing for a period of 28 days. They were then subjected to compressive strength, water absorption, and efflorescence tests in accordance with Bureau of Indian standards (BIS) specifications. The results of the tests indicated that OPC stabilization resulted in blocks that met the specifications of BIS. Addition of SBA increased the compressive strength of the blocks and slightly increased the water absorption but still met the standard requirement of BIS code. It is concluded that addition of SBA to OPC in stabilized block manufacture was capable of producing stabilized blocks at reduced OPC content that met the minimum required standards.

This study examines the behavior of fatigue interaction-palm fibers in the soil-cement as an elastic foundation pavement. Experimental behavior in sandy-clay type soil stabilized cement, with 6% and the amount of cement mixed-palm fibers as reinforcement to the number of 0% and 0.50% of the dry weight of the soil. Fatigue with repeated load testing using a UTM-5P / 14P and type testing Confined Repeated Strain Axial Load Test and visual interaction microstructure-palm fibers examined by Scanning Electronic Microscopy (SEM). The test specimen is done at 28 days, the loads are applied: is loading stress = 1500 kPa, confining stress = 100 kPa, loading frequency 1,5Hz. The results obtained showed reinforcement palm-sugar 0.50% increase resilience modulus degradation of 6,50% and microstructural observations indicate cement hydration bind soil particles cover the surface of palm fibers. The results of the other is the interaction of the fibers improve the strength of soil-cement and pavement a long life.
