Why Concrete Stays Cooler Than Asphalt

If you’ve ever walked barefoot on asphalt in the summer, you know how hot it can get.

That’s because asphalt absorbs and retains heat, while concrete reflects a larger portion of sunlight. This property is known as albedo, or a material’s ability to reflect solar energy.

Concrete’s lighter color naturally reflects more heat, which means:

Lower surface temperatures
More comfortable walkways and patios
Less heat buildup around your home

In contrast, asphalt’s dark color absorbs heat, often making it significantly hotter — sometimes by 20–40°F or more under direct sunlight.

This difference can have a real impact, especially in areas like:

Driveways
Pool decks
Outdoor living spaces

Beyond comfort, cooler surfaces can also contribute to reducing the “heat island effect” in developed areas, where large amounts of dark surfaces trap heat and raise surrounding temperatures.

Choosing concrete isn’t just about durability — it can also improve the usability of your outdoor space during warmer months.

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 ...

Why It Matters Wednesday: Why Pozzolans Matter

Why Pozzolans Matter Concrete is more than just cement, water, and stone. One of the most important ingredients used to improve concrete performance is something called a pozzolan . Pozzolans play a critical role in making concrete stronger, more durable, and longer lasting. What is a Pozzolan? A pozzolan is a material added to concrete that reacts chemically with calcium hydroxide during the curing process. This reaction strengthens the internal structure of the concrete and improves its overall performance. Common pozzolans include: Fly ash Silica fume Slag cement Natural volcanic materials These materials enhance concrete beyond what cement alone can achieve. Why Pozzolans Matter Pozzolans significantly improve concrete quality in several ways: Increased Strength Pozzolans strengthen the internal bond within the concrete, resulting in a stronger final product. Improved Durability Concrete with pozzolans is more resistant to weather, moisture, and wear....
