Resumo
Devido ao baixo preço e alta maleabilidade, atualmente, o plástico é um dos materiais mais utilizados em embalagens. Porém, com seu amplo uso e pouca incidência de reciclagem, o plástico descartado de forma incorreta afeta o meio ambiente, interferindo no habitat de animais e impactando negativamente a vida humana. Além dos resíduos domésticos, a indústria da construção civil também produz em menor escala resíduos impossibilitados de reciclagem classificados como Resíduos da Construção Civil – Classe C (RCC-C), que conta como maior representante o gesso. Com a crescente conscientização com o meio ambiente e busca por alternativas para utilização destes resíduos, esta pesquisa tem como objetivo apresentar a utilização de garrafas PET e gesso no interior de blocos de concreto, assim como avaliar o impacto na resistência a compressão dos mesmos. Para a realização dos testes confeccionou-se blocos e meio blocos de concreto com garrafas PET vazias e com garrafas preenchidas de gesso, além de blocos maciços para efeito de comparação das resistências. Com a utilização de uma prensa hidráulica, observou-se com o ensaio de resistência dos blocos que os blocos apresentaram resultados inferiores ao esperado. Apesar disto, os blocos ainda sim apresentam-se como uma solução viável para o mercado da construção, garantindo a qualidade estrutural e minimizando os impactos ambientais negativos provenientes do descarte incorreto das garrafas PET
Due to the low price and high malleability, currently, plastic is one of the most used materials in packaging. However, with its widespread use and low incidence of recycling, the plastic disposed of incorrectly affects the environment, interfering in the habitat of animals and negatively impacting human life. In addition to domestic waste, the construction industry also produces, on a smaller scale, waste that is not recyclable and classified as Civil Construction Waste - Class (RCC-C), which has gypsum as its largest representative. With the growing awareness of the environment and the search for alternatives for the use of these residues, this research aims to present the use of PET bottles and plaster inside concrete blocks, as well as to evaluate the impact on their compressive strength. To carry out the tests, blocks and half blocks of concrete were made with empty PET bottles and bottles filled with plaster, in addition to solid blocks to compare the effect of comparing resistances. With the use of a hydraulic press, it was observed with the resistance test of the blocks that the blocks present results below the expected resistance. Despite this, the blocks still present themselves as a viable solution for the construction market, guaranteeing structural quality and minimizing the negative environmental impacts resulting from the incorrect disposal of PET bottles and class C construction waste.
