Concrete 101: Creep in Concrete

Concrete is strong, but like all building materials, it changes under pressure. Over time, concrete subjected to a constant load can slowly deform — a phenomenon called creep.

What is Creep?

Creep is the gradual, long-term movement of concrete when it’s under sustained stress.
It doesn’t mean the concrete is failing — it’s simply adjusting to the load over time.
The effect is most noticeable in tall buildings, bridges, and structural members like beams or columns.

Factors That Affect Creep

Load Level: Heavier loads increase creep.
Moisture & Humidity: Higher moisture conditions often result in more creep.
Mix Design: High-strength, dense concretes generally creep less than lower-strength mixes.
Age of Concrete: Younger concrete is more prone to creep than older, fully cured concrete.

Why It Matters

Engineers account for creep when designing large structures. By understanding how concrete behaves over decades, they can ensure bridges, towers, and other projects remain safe and serviceable long into the future.

👉 Creep might sound like a flaw, but in reality, it’s a predictable part of concrete’s long-term performance.

Concrete 101: Understanding the Concrete Mix – What’s in the Bag?

🧱 Concrete 101: Understanding the Concrete Mix – What’s in the Bag? New to concrete? No problem. Whether you're pouring a slab for a shed or managing a new driveway install, it helps to know what’s actually in a concrete mix—and why it matters. At its core, concrete is a simple recipe: cement , aggregates , and water —but slight changes to that recipe can have a big impact on how your project performs. Let’s break down what goes into a standard mix and what each ingredient can do for your concrete. 🧪 The Basic Ingredients 1. Cement Cement is often confused with concrete, but it’s just one part of the mix. It's the binding agent —when combined with water, it reacts chemically (a process called hydration ) to create a paste that hardens and glues everything together. Most mixes use Portland cement , which is widely available and compatible with a variety of applications. 2. Aggregates ( Sand and Gravel ) Aggregates give concrete its volume and strength. These can ...

Concrete 101: A Brief History of Concrete

Concrete 101: A Brief History of Concrete RLW: The Mixer Minute Concrete is one of the most widely used building materials in the world today—but it’s not a modern invention. Its history stretches back thousands of years, proving just how reliable and versatile it is. Here’s a quick look at concrete through the ages. ✅ 1. The Ancient Origins The earliest forms of concrete date back to ancient civilizations. The Egyptians used a mixture of mud and straw for bricks and later developed a lime and gypsum mortar. But it was the Romans who perfected the use of concrete, mixing volcanic ash with lime and water to create structures that still stand today. ✅ 2. Roman Concrete Marvels The Romans built roads, aqueducts, and massive structures like the Colosseum and the Pantheon dome using concrete. Their formula allowed the material to resist cracking and even grow stronger over time when exposed to seawater. ✅ 3. Concrete Disappears—and Returns After the fall of the Roman Empire, ...
