LISTA DE EXERCÍCIO - 02
AGLOMERANTES:
1) Com base no que você estudou sobre cal aérea e hidratada, elabore um texto descritivo onde você se posicione sobre qual tipo de produto acha mais vantajoso utilizar. A sua justificativa deve ser embasada em duas informações que você deverá pesquisar em lojas de material de construção: preço e rendimento de cada produto. Sua argumentação deve conter entre 10 e 20 linhas e será enviada ao professor, constituindo um dos objetos de avaliação da disciplina.
