Item Análise de viabilidade entre concretos dosados pelos métodos da ACCP/ACI e IPT/USP(2019-07-08) Nascimento, Lucas Costa do; Araújo, Fernanda Wanderley Correa; http://lattes.cnpq.br/7616387320307731; http://lattes.cnpq.br/7949189322240161The proper determination of the proportion of materials in the production of a concrete can imply a significant reduction of the final cost of work, since it is one of the materials most used in construction. The wide use in civil works indicates the need to rationalize the quantity of materials composing the mixture by determining an efficient feature that allows an adequate interconnection between the different physical properties required of a concrete with the lowest possible cost. This study presents a comparative analysis of physical and mechanical properties, material consumption and cost between two dosing methods: the one proposed by the Brazilian Portland Cement Association (ABCP), which is an adaptation of the ICA method, and the experimental method IPT / EPUSP. From initial parameters (concrete volume, compressive strength, cone trunk abatement and physical properties of cement and aggregates) and following the prescriptions and steps described by the methods, the respective traces were determined for the molding of a certain amount of ruptured specimens aged 14 and 28 days. With the obtained data, it was verified that both methods are able to provide concretes with the predefined physical properties. In terms of cost, the financial analysis of material consumption, based on the reference prices of the National System of Costs Survey and Civil Construction Indices (SINAPI / PE April-2019), verified a greater material saving by the IPT / EPUSP.Item Classificação dos resíduos de construção e demolição (RCD) e potencialidades de reciclagem ou reutilização em obras de edificação na região de Ipojuca: Muro Alto(2017-09-01) Nascimento, Lucas Costa do; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/7949189322240161The environmental concern is recurrent in today's world, and the practices developed by both society and government aim to reduce the number of waste disposed indiscriminately in the environment are inevitable. Construction and demolition waste (RCD) discarded and exposed irregularly in the urban environment, generates the proliferation of vectors, among other negative aspects, being this over the years studied, assuming a possible material potential for reuse. With the objective of quantifying and characterizing the types of construction and demolition residues from buildings (vertical constructions) in the city of Ipojuca: Muro Alto, and later establishing a specific use for the reuse of these wastes, a field research was carried out , from questionnaires and the consultation of PGRCCs of medium and large companies, in the indicated districts. It was concluded that large construction companies that have certifications such as ISO 9001 and 14001, follow, in great part, waste management policies. Meanwhile, the medium-sized construction company analyzed, without strict control and planning, the RCD generated on site. Much of the waste generated by the companies is rubble or debris: remnants of mortars, concrete - demolition, remains of tiles, class A waste, which can be reused and recyclable.
