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....
Why It Matters Wednesday: Proper Form Setting in Concrete When it comes to concrete, what you don’t see is often more important than what you do. Before the first yard of concrete ever hits the ground, proper form setting determines whether your driveway, patio, sidewalk, or heated slab will perform for decades — or start failing within a few seasons. 1. Straight Lines & Clean Edges Forms are what create the finished shape of your concrete. If they aren’t set square, straight, and braced correctly, you’ll see it forever. Crooked edges, uneven borders, and inconsistent thickness all trace back to poor form work. 2. Proper Pitch & Drainage In our Pennsylvania climate, drainage is everything. Forms must be set with the correct slope to move water away from foundations, garages, and walkways. Even a small mistake in pitch can cause standing water, ice buildup, or long-term damage. 3. Consistent Thickness = Structural Strength Forms control slab thickness. If they’re n...
