玄武岩繊維補強コンクリートの耐久性：耐酸・耐アルカリ性、耐熱性、および凍結融解に対する保護
Why Concrete Durability Needs More Attention Concrete is one of the most widely used construction materials in the world. It is used in dams, bridges, tunnels, roads, buildings, industrial floors, precast components, and many other structures. It has good compressive strength. It is also easy to shape and widely available. But ordinary concrete still has clear limits. It has poor toughness. It is weak in tension. It can crack under impact, shrinkage, bending, temperature change, and repeated load. It can also suffer from sulfate attack, chloride attack, freeze-thaw damage, high temperature damage, and long-term water erosion. Once cracks appear, durability problems become more serious. Water can enter the concrete. Salt […]
