| 发明名称 | Cementitious matrix and fiber reinforced cement based mixture | ||
| 摘要 | A cementitious matrix in which the development of early strength is fast, the hydration heat temperature is small, and the amount of shrinkage during curing is small, while keeping the fluidity when concrete is fresh, is provided. The cementitious matrix is characterized by comprising 100 parts by weight of Portland cement, 5 to 30 parts by weight of silica fume, 5 to 25 parts by weight of limestone powder, 30 to 80 parts by weight of at least one of ground blast furnace slag or fly ash, at least one chemical admixture, water, and 70 to 150 parts by weight of aggregate having a largest aggregate diameter of 1.2 to 3.5 mm. | ||
