The invention relates to the technical field of building concrete, in particular to novel high-ductility refractory concrete, which is composed of a component A and a component B. The component A is composed of the following components in percentage by mass: 5-10% of special cement, 20-30% of Portland cement, 0.1-0.2% of cellulose ether, 0.5-0.8% of latex powder, 25-40% of quartz sand, 25-30% of emery, 0.02-0.03% of an expanding agent, and 0.03-0.04% of an antifoaming agent; and the component B is at least one of polyvinyl alcohol fibers or derivatives thereof, and the mass of the component B is 1-2% of the mass of the component A. The high-ductility refractory concrete provided by the invention has good fire resistance and self-healing ability, and shows good toughness, equivalent bending strength, breaking strength and compressive strength.
本发明涉及建筑用混凝土技术领域，一种新型高延性耐火混凝土，该高延性耐火混凝土由A组分和B组分组成，A组分按质量百分比计，由下述各组分组成：特种水泥：5‑10％，硅酸盐水泥：20‑30％，纤维素醚0.1‑0.2％，乳胶粉：0.5‑0.8％，石英砂：25‑40％，金刚砂：25‑30％，膨胀剂：0.02‑0.03％，消泡剂：0.03‑0.04％；且B组分为聚乙烯醇纤维或其衍生物中的至少一种，其量为A组分质量的1‑2％。本发明的高延性耐火混凝土具有良好的耐火性、自愈合能力，并且表现出良好的韧性、等效弯曲强度、抗折强度、抗压强度。
