We’ve already learned that a cement pig is a specialized pneumatic truck trailer designed for hauling and storing cement at a job site. So you might be wondering, what exactly is cement, and what’s the difference between cement and concrete? The two labels are often used interchangeably, but in reality, cement is just one of the ingredients used to create concrete.
Cement is the binder that is mixed with water and other aggregates like gravel or sand to make concrete. If a construction job calls for a large quantity of concrete (like a highway), the job site may have cement pigs or other storage containers for each of the ingredients and aggregates that go into making concrete. Cement is made up of calcium compounds, silica, alumina, and iron oxide, and is often produced by processing raw ingredients like limestone. A special heating process helps transform and break down the raw materials until a very specific chemical formula is achieved. Cement is sold and used in powder form, and is easily moved in large quantities by trucks hauling pneumatic trailers, and moved at the job site through a combination of steel tubes and a blower.
Concrete is a specific mixture of cement, water, and aggregates that when first mixed is semi-liquid and flows easily to be poured and formed into specific shapes while wet. Wet concrete eventually hardens through a chemical curing process called hydration. Hardened cement is an incredibly hard and durable stone-like material that is great for projects that will be exposed to harsh conditions. Concrete doesn’t require maintenance, lasts a long time, and is one of the most commonly used building material in the world – everything from homes, to schools, to dams, to roadways are constructed with concrete.
