High-bending-resistance super-early-strength UHPC with initial setting time longer than 30 min and preparation method of high-bending-resistance super-early-strength UHPC
The invention discloses high-bending-resistance super-early-strength UHPC with initial setting time longer than 30 min and a preparation method thereof.The high-bending-resistance super-early-strength UHPC is prepared from sulphoaluminate cement, Portland cement and a setting adjusting component and is characterized in that the UHPC is prepared from, by weight, 400-630 parts of sulphoaluminate cement, 100-200 parts of Portland cement, 2-9 parts of the setting adjusting component, 1-16 parts of an early-strength component and 0.1-30 parts of a reinforcing component. Due to the synergistic hydration effect of the sulphoaluminate cement and the Portland cement and the existence of factors and effects of the reinforcing component, the early strength component, the coagulation regulating component A, the coagulation regulating component B and the like, the high 3h breaking strength (gt; 14 MPa) and 3h compressive strength (gt) of the mainstream; the cost is greatly saved, and the initial setting time exceeds 30 minutes.
本发明公开了一种初凝时间大于30min的高抗折超早强的UHPC及其制备方法，包括硫铝酸盐水泥、硅酸盐水泥、调凝组分，其特征在于，所述UHPC包括以下重量份的原料：硫铝酸盐水泥400‑630份、硅酸盐水泥100‑200份、调凝组分2‑9份、早强组分1‑16份、增强组分0.1‑30份。本发明因硫铝酸盐水泥与硅酸盐水泥的协同水化效应、增强组分、早强组分、A调凝组分、B调凝组分等因素作用的存在，达到了超早强UHPC中较高的3h抗折强度(>14MPa)和主流的3h抗压强度(>37MPa)，大量节省成本，初凝时间超过30min。
