Rubber modified strain hardening alkali-activated composite material and preparation method thereof
The invention discloses a rubber modified strain hardening alkali-activated composite material and a preparation method thereof, and belongs to the technical field of concrete. The rubber modified strain hardening alkali-activated composite material is prepared by replacing 25-100% of natural fine aggregate with rubber powder in an isovolumetric manner and strictly controlling the replacement rate of the rubber powder to the natural fine aggregate. The R-SHAAM shows the optimal axial tensile property under the condition that the volume substitution rate of the rubber powder is 25%, the tensile strength is improved by 8.1%, and the ultimate tensile strain is improved by 4.1%. And when the rubber completely replaces the natural aggregate, the R-SHAAM still keeps relatively good compression resistance and tensile property, and meets the requirements of structural application.
本发明公开了一种橡胶改性应变硬化碱激发复合材料及其制备方法，属于混凝土技术领域。本发明将橡胶粉末等体积取代25‑100％的天然细骨料，通过严格把控橡胶粉末对天然细骨料的替代率，制备得到一种橡胶改性应变硬化碱激发复合材料。在25％橡胶粉末体积替代率下，R‑SHAAM表现出最佳的轴向拉伸性能，拉伸强度提高了8.1％，极限拉伸应变提高了4.1％。并且当橡胶完全替代天然骨料时，R‑SHAAM仍保持有较好的抗压性能与抗拉性能，符合结构应用的要求。
