国际国内对材料发展的分析认为,混凝土仍是今后几十年最主要的结构材料,且需要量大。它的优点在于抗压强度高、耐久性好、能耗低、可就地取材,但缺点在于抗拉强度低、脆性随抗压强度的提高而增加,因而限制了高强混凝土的实际使用。在第七届水泥化学国际会议上,各国学者亦呼吁向金属高分子材料学习,必须 The international and domestic analysis of material development believes that concrete is still the most important structural material in the next few decades and needs a large amount. Its advantages lie in high compressive strength, good durability, low energy consumption, and availability of materials in situ, but the disadvantage is that the tensile strength is low and the brittleness increases with the increase of the compressive strength, thus limiting the practical use of high-strength concrete. At the 7th International Conference on Cement Chemistry, scholars from various countries also called for studying metal polymer materials.
