Become a cement and concrete pouring expert with this blog. Learn the difference between cement and concrete, what makes them work, and how to use them in your own projects.
Whether you’re working on a large scale construction project or simply pouring a new sidewalk out back, cement and concrete are essential building materials. But, there is some confusion surrounding the terms. Namely, what is the difference between cement and concrete? Although they may seem interchangeable, they are very different in fact. The former is an ingredient used to make concrete (and mortar), while the latter is the end-product of combining aggregate with cement. A mixture of water, sand or gravel, and lime or calcium oxide has been used for thousands of years as a building material for housing and other structures. Here we break down how it works, how to use it in your projects, and more. If you have any questions about using cement or concrete products in your home, don’t hesitate to ask one of our experts at The Home Depot online or in-store today!
People often use the words “cement” and “concrete” interchangeably, but they are not the same thing. Cement is an ingredient of concrete and mortar. It is a fine powder that acts as a binding agent when mixed with water and aggregates such as sand, gravel or crushed stone. Concrete is made up of cement, water and aggregate materials such as sand, gravel or crushed stone. It’s generally used for building foundations, flooring, walls and for other non-aesthetic outdoor projects.
Cement 101:
Cement is basically a paste made by grinding together limestone, clay and other rock-like materials. The paste is then heated to high temperatures to create a rock-like substance known as clinker which is then ground into a fine powder.
This powder usually contains limestone, clay, shells or silica sand with iron oxide. The combination of this material creates a grey powder that produces the “glue” that holds concrete together like adhesive.
Concrete 101:
Concrete is basically cement mixed with aggregates (sand or gravel) along with water to create a paste that hardens over time when mixed together. This mixture can be poured into forms or molds to create different shapes of concrete and is commonly used
Cement is a mixture of sand, gravel and other materials. It is a powdered substance that is mixed with water to create a paste. When this paste is mixed with pebbles or sand, it creates concrete. The use of concrete dates back thousands of years to the Romans who created concrete using volcanic ash. Today’s modern cement can be traced back to the early 1800s when Joseph Aspdin invented the first type of Portland cement by burning finely ground chalk and clay until a clinker was produced.
The term “cement” is often used interchangeably with concrete, but they are not the same thing. While cement is an ingredient in concrete, it is not the main ingredient.

CEMENT is a powder which hardens when mixed with water, and can bind sand and aggregates into a hard, solid mass called concrete. Concrete is just cement mixed with aggregate, usually sand and small stones.
What is the difference between cement and concrete?
There is a difference between cement and concrete. Cement is a fine binding powder that is never used alone, but is a component of both concrete and mortar, as well as stucco, tile grout, and thin-set adhesive. Mortar is composed of cement, fine sands and lime; it is used a binding material when building with brick, block, and stone. Concrete is made up of cement and aggregate (sand or other materials) which are held together by water.
Concrete is one of the most widely used construction materials in the world because of its durability, strength and ability to withstand weathering elements such as wind and rain. It has had a long history from its origins in pre-history to today’s high tech structures.
When you are working with a cement based product, you are working with a material that begins to set in as little as 10 minutes and can be completely hard in less than 24 hours. As it sets, it exothermically releases heat, which must be dissipated at the surface of the slab. If it cannot dissipate through the top surface, it will try to dissipate through the sides of the formwork.
This is where expansion joints come into play. They allow for the concrete to expand or contract without cracking or spalling. When you see someone using a concrete saw cutting a groove along a sidewalk, they are probably not just being decorative. They are allowing the concrete to move rather than preventing it from moving and suffering serious damage (cracking).
Many people use the terms cement and concrete interchangeably, and although the two terms are closely related, they’re not the same thing. Cement and concrete each have their own unique properties and uses. Concrete is a mixture of water, aggregate (rock, sand, or gravel), and Portland cement. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardened mass, or concrete, will take on the strength of the aggregates used while retaining a smooth, marble like finish.
The most common form of cement is Portland cement. This is not a brand name, but rather a generic term much like stainless steel. The name comes from its similarity to Portland stone which is quarried on the Isle of Portland located off England’s southern coast. The crushed rock is combined with other ingredients such as iron ore and then heated to about 2,700 degrees Fahrenheit in a gigantic rotary kiln. The intense heat causes chemical changes in the ingredients resulting in what is known as clinker which resembles small stones about 3
Cement is a mixture of limestone and clay, usually in the form of small pellets or chunks. As the material decomposes under high heat, it becomes a powder that hardens when it comes into contact with water. The key ingredient in cement is calcium, which can be found in many forms of limestone. In order for concrete to harden, this calcium must be present in large quantities.
Concrete is made up of several different compounds, including sand, aggregate, gravel and water. It’s easy to think of concrete as a solid substance. However, the cement is actually held together with a liquid mix of water and other chemicals. This liquid mix is called mortar. The mortar helps to keep the cement from drying out and prevents clumping together when exposed to moisture.
When it comes to pouring concrete, there are two main types: wet and dry. Wet pouring involves mixing water with a dry mixture before adding it to the formwork. Dry pouring involves mixing dry material with a liquid mixture before adding it to formwork. A third type of pour – known as the ‘wet-dry’ method – uses a combination of wet and dry material in an alternating pattern to create concrete that’s even stronger than regular concrete!
Both methods have their advantages and disadvantages
