The Problem With Concrete

Concrete is responsible for 8% of humanity’s carbon emissions because making its key ingredient - cement - chemically releases CO2, and because we burn fossil fuels to make it happen.

Portland cement - the most common type of cement used worldwide, made with limestone
Limestone - a hard sedimentary rock, composed mainly of calcium carbonate (which is also in shells & eggs)
Cement - a powder used in construction that’s made by grinding clinker with other minerals and mixing with water to form a paste that sticks to sand, gravel or crushed stone to make concrete
Concrete - a building material made by mixing cement with water to form a paste that gains body through fillers like sand and gravel
Clinker - an intermediate marble-sized product in cement production created by sintering limestone with clay and other things
Sinter - to turn a powdery solid into a single mass by heating it without liquefaction
Mortar - another building material (used to adhere bricks or stones together) made by mixing cement with water and sand
Calcination - the process of heating a substance to a high temperature, but below its melting point, so it thermally decomposes (like limestone into lime & CO2)
Process emissions - the name for the CO2 that comes from limestone when it thermally decomposes

Beschreibung

From the creators of the popular science show with millions of YouTube subscribers comes the MinuteEarth podcast. Every episode of the show dives deep into a science question you might not even know you had - but once you hear the answer, you’ll want to share it with everyone you know. Our team of scientists digs into the research and breaks it down into a short, entertaining explanation jam-packed with science facts and terrible puns. We’ll tell the incredible story of how monkeys crossed the Atlantic ocean on natural rafts, and we’ll explain why it gets hotter the deeper you dig underground.
