| 摘 要： | 高炉矿渣粗骨料(BFSA)可用于配制高强混凝土(HSC)。通过5个不同水胶比(0.30、0.35、0.40、0.45、0.50)的BFSA混凝土与普通骨料混凝土(基准混凝土)在7d和28d龄期的抗压强度等力学性能比较,得出以BFSA生产的高强混凝土具有一系列优良性能,如不同水胶比的BFSA混凝土的抗压强度比相应的基准混凝土高出26%~87%;BFSA混凝土比基准混凝土具有更低的渗透性、更高的劈拉强度和更低的脆性。试验过程中,以10%的硅粉(SF)等量取代普通硅酸盐水泥,并掺加超塑化剂,从而有效改善BFSA混凝土的性能。为了便于比较,试验过程中保持所有混凝土拌合物坍落度相同。

| Abstract: | Blast furnace slag aggregates(BFSA) were used to produce high-strength concretes(HSC).Different water-binder ratios(0.30,0.35,0.40,0.45 and 0.50) were used to do tests of 7-day and 28-day compressive strength and other properties of conventional(reference) concrete and BFSA concrete.Super-plasticizer and 10% silica fume were used to improve BFSA concretes.Slump was kept constant throughout this study.It concluded that compressive strength of BFSA concretes are approximately 26%～87% higher than reference concretes for different water-binder ratios.These concretes also have lower water absorption,higher splitting tensile strength and lower brittleness. |
