A faixa granulométrica recomendada para a areia utilizada em argamassa é apresentada na Tabela 9. O uso de cal hidratada não é essencial, mas pode ser útil para aumentar a coesão da mistura ao usar areias muito grossas (módulo de finura maior que 3). Portanto, a alternativa correta é a letra C) Ambas as afirmações são verdadeiras.
