Informative

Informative is where I post general notes and observations from working with concrete and cement-based materials.

These aren’t always step-by-step tutorials. They’re more like field notes: what’s changing in materials, what works in practice, and how to think about common problems before they happen.

If you like the “why” behind the how-to guides, you’ll probably enjoy this section.

Alkali–Carbonate Reaction: How It Differs from ASR and What to Watch For

Introduction Alkali–carbonate reaction is a chemical reaction in concrete that happens when alkalis in cement react with carbonate rock in the aggregate. It can cause slow cracking and changes in stiffness over time. This article explains what to watch for and how you might address it in a DIY setting. ACR differs from ASR in […]

Basalt Rebar: Where It Makes Sense and How to Detail It in Marine Zones

Introduction Basalt rebar is a non-metal reinforcement made from basalt rock fibers that can replace traditional steel in concrete. It’s designed to resist corrosion in coastal and marine settings. This introduction covers what basalt rebar is and how it fits into marine-zone detailing. In marine zones, basalt rebar helps reduce rusting and long-term maintenance compared

Reinforcement Beyond Steel Rebar: Basalt, FRP, Couplers, and Headed Bars

Introduction Reinforcement beyond steel rebar means using non-metallic or alternative materials to strengthen concrete, such as basalt fibers, FRP, couplers, and headed bars. They can resist corrosion and may install differently than traditional rebar. Always check manufacturer instructions and local rules to confirm suitability for your project. FRP rebar offers a value proposition in durability
