Quarrying quartz and cutting it into some fancy lattice? Sounds like a lot of work for a little gain. Quartz is hard but brittle, so putting it in a lattice that has to take bending or shear is a recipe for cracking. Concrete already gets its strength from the cement matrix and the steel fibers, and adding quartz just adds weight and a lot of grinding. If you want to boost the mix, stick with cheap aggregates or steel reinforcement; if you’re after a high‑performance composite, look at carbon or glass fibers. Quartz lattice could work in very specific, low‑stress applications, but for general concrete or metal reinforcement it’s overkill. Just keep the design simple and the costs low.
