Composite modified cement-based material and preparation method thereof
The invention relates to a composite modified cement-based material and a preparation method thereof. The composite modified cement-based material is prepared from the following raw materials in parts by weight: 180 to 220 parts of sand, 70 to 90 parts of cement, 15 to 25 parts of fly ash, 0.13 to 0.17 part of nano titanium nitride, 0.7 to 0.9 part of polyamide fiber, 0.3 to 0.5 part of abaca fiber and 0.05 to 0.11 part of coupling agent. Through the synergistic effect of the raw material components, the breaking strength, the compressive strength, the splitting tensile strength, the drying shrinkage resistance and the frost resistance of the composite modified cement-based material can be compositely enhanced, the interior of the cement-based material is connected to form a net-shaped connection structure, the mechanical strength and durability of the cement-based material are enhanced, and the service life of the cement-based material is prolonged. The interlocking force between aggregates is improved, the toughness of the cement-based material is remarkably improved, meanwhile, the preparation process is simple, and good economic benefits are achieved.
本申请涉及一种复合改性水泥基材料及其制备方法。所述复合改性水泥基材料，包括以下重量份数的原材料：砂180～220份，水泥70～90份，粉煤灰15～25份，纳米氮化钛0.13～0.17份，锦纶纤维0.7～0.9份，蕉麻纤维0.3～0.5份，偶联剂0.05～0.11份。本申请中各原料组分的协同作用，可复合增强复合改性水泥基材料抗折强度、抗压强度、劈裂抗拉强度、抗干燥收缩性能和抗冻性能，且是水泥基材料内部联结形成网状联接结构，增强了水泥基材料力学强度和耐久性，并且提高了集料之间嵌锁力，显著提高水泥基材料的韧性，同时，本申请制备工艺简单，具有良好的经济效益。
