Porosity
Porosity refers to how many tiny holes or spaces exist within construction materials like concrete, brick, or stone. Think of it like a sponge - the more holes it has, the more porous it is. This is important in construction because it affects how well materials can resist water, how strong they are, and how long they'll last. When you see this term in resumes or job descriptions, it usually relates to testing materials, ensuring quality, or solving problems with water resistance in buildings.
