波特兰水泥是一种被广泛使用的建筑材料。它与骨料混合形成混凝土,便成为一种耐压强度高、经济的、多用途材料。可是这种材料较脆易裂,受到大的弯曲载荷时常常失效。美国克赖伏兰特公司是专门研究化学添加剂的,他们按照用户的要求,配制出一种塑料混凝土,改善了其性能。 Portland cement is a widely used building material. It is mixed with aggregates to form concrete and becomes a high-pressure, economical, multi-purpose material. However, this material is brittle and brittle, and often fails when subjected to large bending loads. The US company Kravlant specializes in chemical additives. They formulated a plastic concrete according to the user’s requirements to improve its performance.
