To investigate the effect of different cooling methods on the uniaxial compressive properties of ultra-high performance concrete (UHPC) after high temperature, 45 specimens with the dimension of 100 mm×100 mm×300 mm were designed and fabricated. The cooling methods and heating temperature were chosen as test variable parameters. Observe the apparent characteristics, quality loss, and failure mode were observed after different high temperatures and cooling methods. The variation law of compressive strength was analyzed. The experimental results show that as the temperature increases, the surface cracks increase. The mass loss rate increases under different cooling methods. A higher mass loss rate occurs under natural cooling with the same temperature. Under natural cooling, the mass loss rate increases rapidly at first and then slowly. An approximately linear increase is presented under water cooling. The compressive strength shows a trend of first slightly increasing and then decreasing. Compared with the normal temperature, with the temperature increase, the maximum compressive strength increased by 18.3% and 13.4% respectively under natural cooling and water cooling. When the temperature reaches 800 ℃, the compressive strength under natural cooling and water cooling decreases to 20.8% and 18.8% of compressive strength at normal temperature, respectively. When the temperature exceeds 600 ℃, the axial deformation ability of blocks is significantly enhanced. Compared with natural cooling, the peak strain under water cooling develops rapidly, but tends to be consistent at 800 ℃. The peak strain under natural cooling and water cooling increases to 2.22 times and 2.24 times the peak strain under normal temperature conditions, respectively. Compared with natural cooling, the elastic modulus under water cooling is relatively small and undergoes three stages: slow decrease, fast decrease, and slow decrease. Based on the experiments, a formula for calculating the residual strength of UHPC after water cooling is proposed, which can provide a basis for evaluating the load-bearing capacity of a building after fire.

为研究不同冷却方式对高温后超高性能混凝土(UHPC)单轴受压力学性能的影响,以冷却方式、受热温度为变化参数,设计制作了45个100 mm×100 mm×300 mm的试块进行高温后的单轴抗压试验。通过观察高温后试块的表观特征、质量损失及破坏形态,分析了冷却方式及受热温度对抗压强度的影响规律。结果表明:随着受热温度升高,试块表面裂纹增多,不同冷却方式下的质量烧失率均增大;相同温度下,自然冷却时试块烧失率大于浸水冷却烧失率,自然冷却下烧失率呈先快后慢的增长趋势,浸水冷却下烧失率近似呈线性增长;抗压强度均呈现先小幅增大后减小的趋势,与常温工况相比,自然冷却、浸水冷却时最大抗压强度分别提高了18.3%和13.4%;受热温度为800℃时,自然冷却、浸水冷却抗压强度分别降低至常温下的20.8%和18.8%;受热温度超过600℃时,试块表现出较好的轴向变形能力;相较于自然冷却,浸水冷却下峰值应变发展较快,但800℃时基本趋于一致,自然冷却、浸水冷却下峰值应变分别增大至常温工况下峰值应变的2.22倍、2.24倍;与自然冷却相比,浸水冷却下弹性模量相对较小,且均经历慢降、快降、慢降3个阶段。基于试验,提出了浸水冷却后的UHPC残余强度计算方法,该方法可为建筑消防灭火后混凝土承载能力评估提供依据。

为研究不同冷却方式对高温后超高性能混凝土(UHPC)单轴受压力学性能的影响,以冷却方式、受热温度为变化参数,设计制作了45个100 mm×100 mm×300 mm的试块进行高温后的单轴抗压试验。通过观察高温后试块的表观特征、质量损失及破坏形态,分析了冷却方式及受热温度对抗压强度的影响规律。结果表明:随着受热温度升高,试块表面裂纹增多,不同冷却方式下的质量烧失率均增大;相同温度下,自然冷却时试块烧失率大于浸水冷却烧失率,自然冷却下烧失率呈先快后慢的增长趋势,浸水冷却下烧失率近似呈线性增长;抗压强度均呈现先小幅增大后减小的趋势,与常温工况相比,自然冷却、浸水冷却时最大抗压强度分别提高了18.3%和13.4%;受热温度为800℃时,自然冷却、浸水冷却抗压强度分别降低至常温下的20.8%和18.8%;受热温度超过600℃时,试块表现出较好的轴向变形能力;相较于自然冷却,浸水冷却下峰值应变发展较快,但800℃时基本趋于一致,自然冷却、浸水冷却下峰值应变分别增大至常温工况下峰值应变的2.22倍、2.24倍;与自然冷却相比,浸水冷却下弹性模量相对较小,且均经历慢降、快降、慢降3个阶段。基于试验,提出了浸水冷却后的UHPC残余强度计算方法,该方法可为建筑消防灭火后混凝土承载能力评估提供依据。

To investigate the effect of different cooling methods on the uniaxial compressive properties of ultra-high performance concrete (UHPC) after high temperature, 45 specimens with the dimension of 100 mm×100 mm×300 mm were designed and fabricated. The cooling methods and heating temperature were chosen as test variable parameters. Observe the apparent characteristics, quality loss, and failure mode were observed after different high temperatures and cooling methods. The variation law of compressive strength was analyzed. The experimental results show that as the temperature increases, the surface cracks increase. The mass loss rate increases under different cooling methods. A higher mass loss rate occurs under natural cooling with the same temperature. Under natural cooling, the mass loss rate increases rapidly at first and then slowly. An approximately linear increase is presented under water cooling. The compressive strength shows a trend of first slightly increasing and then decreasing. Compared with the normal temperature, with the temperature increase, the maximum compressive strength increased by 18.3% and 13.4% respectively under natural cooling and water cooling. When the temperature reaches 800 ℃, the compressive strength under natural cooling and water cooling decreases to 20.8% and 18.8% of compressive strength at normal temperature, respectively. When the temperature exceeds 600 ℃, the axial deformation ability of blocks is significantly enhanced. Compared with natural cooling, the peak strain under water cooling develops rapidly, but tends to be consistent at 800 ℃. The peak strain under natural cooling and water cooling increases to 2.22 times and 2.24 times the peak strain under normal temperature conditions, respectively. Compared with natural cooling, the elastic modulus under water cooling is relatively small and undergoes three stages: slow decrease, fast decrease, and slow decrease. Based on the experiments, a formula for calculating the residual strength of UHPC after water cooling is proposed, which can provide a basis for evaluating the load-bearing capacity of a building after fire.

目前火灾已成为城市灾害的重要形式之一,混凝土作为城市建筑中被广泛使用的建筑材料,国内外学者对普通混凝土高温自然冷却后的力学性能研究较多[16],研究结果均表明随着受热温度的升高,在内部蒸汽压力作用下,混凝土内部会产生大量裂纹及角部剥落现象,从而导致抗压强度逐渐降低。
消防灭火是城市建筑火灾不可或缺的重要举措,消防灭火时混凝土快速降温,内部温度应力分布极不均匀,加速了混凝土裂缝的扩展甚至爆裂,从而引起建筑结构的倒塌。部分学者研究了不同冷却方式对高温后混凝土力学性能的影响。ZHAI等[7]研究表明加热温度达到400℃之前,水冷试样的强度高于自然冷却;加热温度高于400℃时,水冷试样的强度显著下降。柯晓军等[8]研究发现高温后再生混凝土试块残余强度随着温度的升高而逐渐降低;与自然冷却相比,喷水冷却后的残余强度呈现先高后低、再高再低的变化趋势。陈宗平等[9]研究表明冷却方式对再生混凝土抗压强度影响较大,受热温度越高,喷水冷却下再生混凝土强度退化越快。郑钰涛等[10]研究表明在喷水冷却快速降温过程中,混凝土内外温度应力分布不均匀致使裂缝扩展延伸,造成试块抗压强度显著降低。王连坤等[11]研究表明在500℃高温及以上温度时,喷水冷却方式下试块的抗压强度及轴心抗压强度下降更为显著。曲海坤等[12]研究发现高温混凝土经自然冷却后出现强度反弹迹象,在400℃时达到峰值,喷淋冷却使混凝土抗压强度在500℃达到峰值。朱俊儒[13]研究表明浸水冷却方式加速了混凝土裂缝的开展,进而显著影响其受压破坏特征及承载能力。
超高性能混凝土(Ultra-High Performance Concrete,简称UHPC)致密的微观结构使其具有超高的力学性能,从而被广泛应用。目前,已有部分学者[1416]对高温后采用自然冷却方式降温的UHPC力学性能进行了研究,研究结果均表明高温后UHPC残余强度随着目标温度的升高而呈现先升高后降低的趋势。但目前对高温后在浸水冷却方式下UHPC力学性能的相关研究较少,因此,本文通过UHPC高温后不同冷却方式下的力学性能试验,观察UHPC的表观特征、质量损失,分析不同冷却方式对UHPC材料基本力学性能退化的影响规律,以期揭示UHPC在高温后浸水冷却条件下力学性能的劣化机理。
以受热温度T(20℃、200℃、300℃、400℃、500℃、600℃、700℃、800℃)、冷却方式(N为自然冷却、W为浸水冷却)为设计参数,制作了45个棱柱体(100 mm×100 mm×300 mm)试块进行高温后的单轴受压试验,试验设计参数见表1
UHPC材料由P•O 52.5硅酸盐水泥、硅灰、粉煤灰、石英砂、镀铜平直钢纤维、水、减水剂等混合配制而成,水胶比为0.18,具体配合比见表2。综合考虑UHPC的力学及工作性能,钢纤维体积掺量取为2%,钢纤维基本物理特性见表3。采用容积为300 L的立式移动搅拌机对UHPC原料进行拌和,待原料充分混合且浆体具有较好的流动性后,倒入模具、振捣密实后封膜,如图1所示。已有研究表明[17]采用标养+干热的组合养护制度可以显著改善UHPC的高温爆裂性能,基于此,本文分别进行了12 h 150℃干热养护与12 h 200℃干热养护的预试验,根据预试验结果,发现150℃养护的试块仍存在爆裂现象。因此本试验采用的组合养护制度为标准养护(温度20℃、相对湿度95%)28 d后再进行12 h 200℃干热养护。
采用1200℃双门快速高温炉进行高温试验,试验温度分别为200℃、300℃、400℃、500℃、600℃、700℃、800℃,平均升温速率为5℃/min[18],炉内升温曲线如图2所示。为保证高温后试块内外温度一致,达到目标温度后恒温90 min。高温后试块分别采用自然冷却、浸水冷却方式冷却至环境温度。其中,自然冷却是指恒温受热90 min后,打开高温炉炉门,自然降温,待试件冷却后取出试块;浸水冷却是指恒温受热90 min后,立即取出并浸入装满100 L(水温为常温)的水箱中,冷却至环境温度。
1)高温试验:高温中记录发出的声音及气味;待试块冷却至环境温度并静置48 h后,观察UHPC试块的表观特征(颜色、裂纹)变化,记录试块的质量损失。
2)强度试验:采用图3所示的YAJ-12000型微机控制电液伺服加载试验机进行单调受压试验,加载速率为0.2 mm/min;试验中观测试块的裂缝发展,并通过布置在试块侧面中部的横向、竖向混凝土应变片来观测UHPC的横向、纵向应变发展。
当炉温达到300℃时,钢纤维铜镀层被氧化而形成CuO,减水剂受热分解并随水蒸汽挥发,此时有微弱的刺激性气味逸出;炉温达到400℃~600℃时,炉膛内发出钢纤维“撕裂声”,并伴有强烈的刺激性气味;600℃后,钢纤维“撕裂声”基本消失,刺激性气味依然存在。
浸水冷却过程中,当受热温度为200℃~400℃时,出现少许白色烟雾,并伴有轻微且短暂的“嘶嘶”声;当受热温度为500℃~800℃时,出现大量白色烟雾和气泡,并伴有较大“嘶嘶”声,持续约10 min且不断有气泡冒出;试块在整个浸水冷却过程中出现轻微颗粒状表皮剥落现象,特别是受热温度为800℃的试块,浸水冷却后水体较为浑浊。图4所示为高温浸水冷却试块,水箱中铺垫的钢丝网有利于试块底面受冷均匀且能够有效避免试块遇水爆裂时碎体对水箱造成损坏。
图5所示为高温后不同冷却方式下UHPC棱柱体试块的表观特征,由图可知,随着温度的升高,UHPC试块的表观颜色逐渐由深变浅,表面孔隙和微裂纹逐渐增多,试块的敲击声音变得清脆。具体特征如下:
1)受热温度为200℃时,不同冷却方式下的试块表观特征与常温时基本一致,表面无孔隙及可见裂缝,颜色呈深(青)灰色。
2)受热温度为300℃时,试块表面由深灰色变为浅灰色,表面出现细微裂纹;受热温度为400℃~500℃时,不同冷却方式下的试块表面裂纹均有所发展,自然冷却的试块表面无剥落现象,浸水冷却的试块边角有轻微剥落现象,试块敲击声音略显清脆。
3)受热温度为600℃~700℃时,试块表面由浅灰色变为灰白色,表面裂纹较多,自然冷却的试块表面出现黄棕色灼烧点并有少量钢纤维灼烧裂纹,浸水冷却的试块边角UHPC剥落较为严重,试块敲击声音清脆。
4)受热温度为800℃时,试块表面由灰白色变为灰棕色;自然冷却的试块表面有较多钢纤维灼烧裂纹;浸水冷却的棱柱体试块表面未见明显剥落,但水冷干燥后表面裂纹交错相接,深度为2 mm~3 mm的局部表面变得酥软,失去承载能力。
定义I为质量烧失率,即试块高温前后损失的质量与高温前质量的比值,来反映内部微观结构的物理和化学变化,其计算公式为
式中:m为高温前试件的质量;mT为高温后试件的质量。
试块质量烧失率随温度变化的曲线如图6所示,由图可知:
1)试块质量烧失率随温度升高而逐渐增大,呈先快后慢趋势;经历800℃高温后,自然冷却条件下质量烧失率达到11.56%,浸水冷却条件下质量烧失率达到4.79%;与自然冷却相比,浸水冷却时试块质量烧失率较小且增长速度较慢。
2)自然冷却条件下,受热温度不高于400℃时,质量损失率增长较快,主要是由于UHPC基体内自由水蒸发、水泥浆体中C-S-H凝胶中的结合水蒸发,同时伴有Ca(OH)2吸热性脱水所致。受热温度不高于600℃时,质量损失较为平缓,此阶段的质量损失主要是水泥水化产生的Ca(OH)2受热分解后产生的结合水受热蒸发造成的。受热温度不高于800℃时,基体内部结晶水完全丧失,由于混凝土内部Ca(OH)2碳化、CaCO3受热分解,加剧了UHPC基体内结合水蒸发,其质量损失率增长较快。
3)受热温度高于400℃时,UHPC内部分解出大量的CaO、SiO2等碱性氧化物,浸水冷却时能够与自由水结合并重新生成水化晶体(水化硅酸钙),致使质量损失呈先快后慢的增长趋势;相较于自然冷却试块,质量损失增长幅度较小。
随着受热温度的升高,钢纤维与水泥基体的黏结作用逐渐削弱,试块的脆性降低,破坏模式由剪切破坏转为劈裂破坏。具体破坏形态如图7所示,由图可知:
1)受热温度为20℃~300℃时,随着荷载的增大,试块表面无明显变化;接近峰值荷载时,有轻微撕裂声,且出现贯穿性对角斜裂缝;峰值荷载时,可听到“嘭”的爆裂声,并有少量碎屑向四周飞溅,之后裂缝迅速贯穿发展,直至失效。
2)受热温度为400℃~600℃时,当接近峰值荷载时,可听到钢纤维与基体脱黏的撕裂声,破坏时仍能观察到对角斜裂缝,也存在较多的细微竖向裂缝,说明在此温度区间内钢纤维与水泥基体的黏结作用有所削弱,试件破坏后仍保持较好的完整性。
3)受热温度为700℃~800℃时,正式加载前,试块表面已有较多宽粗裂纹连成一片;随着荷载增大,原有裂纹迅速发展并形成贯穿裂缝,试件的破坏过程较为平缓,且无撕裂声;试件破坏后基体横向膨胀明显,竖向裂缝发展充分,呈现出劈裂破坏特征,并伴有粉末状颗粒或表皮部分脱落。
图8所示为试块的单轴受压应力-应变曲线,由图可知:
1)随着受热温度的升高,试块的峰值应变逐渐增大,浸水冷却时试块的峰值应变相对较大,说明高温作用与浸水冷却耦合作用加速了基体内部裂缝的开展,弹性模量下降幅度较大。
2)受热温度为500℃时,UHPC峰值应力仍保持在90 MPa左右,强度较高,混凝土脆性特征明显,因此受热温度不高于500℃时,达到峰值应力后,应力-应变曲线陡然下降;受热温度为600℃~800℃时,达到峰值应力后,应力-应变曲线下降较为缓慢,变形增幅远大于荷载降低幅度,说明经历600℃高温后,UHPC材料的脆性特征发生改变,弹性模量下降较为明显。
3)随着温度的升高,应力-应变曲线逐渐趋于扁平化,曲线包络面积逐渐下降,耗能能力降低。
不同高温及冷却方式下UHPC试块的单轴抗压强度见表4,其中表示实测的单轴抗压强度。轴心抗压强度与温度及冷却方式的关系曲线如图9所示。由图9表4可知:
1)随着受热温度升高,不同冷却方式下抗压强度均呈现先增大后减小趋势,自然冷却时最大抗压强度为136.2 MPa,浸水冷却时最大抗压强度为130.5 MPa,与20℃工况相比,分别提高了18.3%和13.4%。原因在于高温使水泥水化反应更充分,促进了硅灰和粉煤灰中的活性SiO2与水泥水化产物Ca(OH)2之间的火山灰反应,生成C-S-H凝胶,并消耗了对强度有不利影响的部分Ca(OH)2,从而提高了UHPC的强度。受热温度较低时,自然冷却后试块损伤较小,高温养护环境对强度起增强作用;浸水冷却时,试块表面快速降温,内外温度应力分布不均,导致基体内部裂纹快速发展,从而浸水冷却时最大轴心抗压强度相对较小。
2)受热温度超过300℃后,轴心抗压强度显著下降;与常温相比,受热温度为600℃时自然冷却、浸水冷却后轴心抗压强度分别降低了58.8%和44.2%;受热温度为800℃时,自然冷却、浸水冷却后轴心抗压强度分别降至常温下抗压强度的20.8%和18.8%。说明高温作用下UHPC基体内二次水化反应和火山灰反应持续进行,但随着受热温度升高,基体内积聚的蒸汽压力在骨料介质间产生的外张力、钢纤维脱碳氧化、浸水冷却时基体内温度应力的不均匀分布,均会导致大量的裂缝和孔隙形成,对UHPC轴心抗压强度的不利影响更为显著。
3)不同冷却方式下,经历不同高温后的UHPC轴心抗压强度表现出不同规律:①受热温度为200℃时,与自然冷却试块相比,浸水冷却试块轴心抗压强度略有提高,增幅约为2%,原因在于高温下UHPC基体内虽然有自由水和少量结合水损失,但仍有部分基体凝胶未大量分解,浸水冷却后生成水化硅酸钙,基体内部变得致密,且部分水泥熟料产生水化反应,致使浸水冷却条件下轴心抗压强度略高。②受热温度为300℃~400℃时,相比于自然冷却,浸水冷却条件下试块轴心抗压强度较小,降幅为5.9%~8.0%,这是由于浸水冷却使试块内部温度应力分布不均,内部裂缝发展更加充分所致。③受热温度为500℃~700℃时,相比于自然冷却,浸水冷却条件下试块轴心抗压强度有所增大,特别是历经600℃高温后,强度提升了35%,其原因是高温下基体内C-S-H结晶变化显著,孔隙率增大,Ca(OH)2被大量分解,致使强度急速降低,浸水冷却后CaO和SiO2分解物产生部分水化晶体,导致强度较自然冷却试块有所提高。④经历800℃高温后,与自然冷却相比,浸水冷却条件下轴心抗压强度下降,降幅为10%,这是由于浸水冷却加剧了基体内部温度应力的不均匀分布,表面2 mm~3 mm深度内变得酥软起皮,从而失去承载能力所致。
随着荷载的增大,试块表面大面积开裂鼓起,应变片所测数据已不能真实反映应变情况,因此定义试块上、下端面相对位移与棱柱体高度之比为平均峰值应变,并以此分析试块的应变发展规律。经受不同高温及冷却方式后,UHPC试块峰值应变如图10所示,由图可知:
1)常温下试块的平均峰值应变ε0约为7.430×10-3,随着温度的升高,不同冷却方式下试块平均峰值应变大小的差异性逐渐变大。
2)T≤300℃时,2种冷却方式下的峰值应变相差不大,且基本保持同一水平;T≥400℃时,相较于自然冷却,浸水冷却条件下峰值应变增长较快,并在700℃时峰值应变相差最为明显,此时自然冷却下平均峰值应变约为1.197×10-2(1.61ε0),浸水冷却下平均峰值应变约为1.394×10-2(1.87ε0)。
3)T=800℃时,两者峰值应变基本趋于一致,此时自然冷却下峰值应变约为1.613×10-2(2.22ε0),浸水冷却下峰值应变约为1.667×10-2(2.24ε0)。
所对应的割线模量记为试块的弹性模量,不同受热温度及冷却方式下试块相对值变化关系如图11所示,其中相对值是指不同高温下的与常温下的之比。由图11可知:
1)随着受热温度的升高,试块逐渐降低,大致经历慢降(20℃≤T<300℃)、快降(300℃≤T<600℃)、慢降(600℃≤T<800℃)3个阶段,且差异性逐渐缩小并趋于一致。受热温度由500℃升至600℃时,降幅较为显著,自然冷却、浸水冷却下下降幅度分别为20.9%、20.1%。
2)不同冷却方式下,下降趋势大致相同,但下降幅度不同。受热300℃时,自然冷却下降低幅度约为11.7%,浸水冷却下降低幅度约为21.2%。受热温度为600℃时,自然冷却条件下,降低幅度约为71.6%;浸水冷却条件下,降低幅度约为75.3%。受热温度为800℃时,自然冷却、浸水冷却下分别降至常温下的13.6%、11.7%,降幅基本趋于一致。
为便于研究高温水冷后UHPC轴心抗压强度的变化规律,定义UHPC高温后的抗压强度与常温下抗压强度之比为相对抗压强度;对温度进行无量纲化处理,定义相对温度RT=(T-20)/800(20℃≤T≤800℃)。归一化处理的高温水冷后相对抗压强度与相对温度关系试验曲线如图12所示。
对试验曲线进行数据分段回归分析,其中20℃~200℃采用线性函数拟合,200℃~800℃采用多项式拟合,得到高温水冷后UHPC抗压强度与温度关系拟合曲线如图12所示,其相关系数R2=0.974,试验结果与拟合结果具有较好的一致性,具体表达式如下:
利用式(2)、式(3)对水冷后UHPC相对抗压强度进行计算,结果见表5,由表可知,计算值与试验值之比的平均值为1.001,标准差为0.04,说明计算方法合理可靠。
通过对45个UHPC试块进行高温试验,研究了试块在不同冷却方式下的受压力学性能,根据试验现象及数据分析,得出如下结论:
1)随着温度的升高,UHPC质量烧失率增大;自然冷却下烧失率先快后慢的增长趋势较为明显,浸水冷却下烧失率大致呈线性增长。
2)随着温度的升高,钢纤维与水泥基体的黏结作用削弱,试块表现出较好的塑性变形能力,受热温度超过600℃时,试块轴向变形能力显著增强,破坏模式由剪切破坏转为劈裂破坏。
3)高温冷却后,试块抗压强度均呈现先小幅增大后降低的变化规律,与常温下相比,自然冷却、浸水冷却时最大抗压强度分别提高18.3%和13.4%;目标温度800℃时,自然冷却、浸水冷却抗压强度分别降低至常温下抗压强度的20.8%和18.8%。
4)随着温度的升高,相较于自然冷却,浸水冷却下峰值应变发展较快,但最终趋于一致;与常温工况相比,800℃时自然冷却、浸水冷却下峰值应变分别达到常温工况峰值应变的2.22倍、2.24倍;与自然冷却相比,浸水冷却下弹性模量相对较小,且均经历慢降、快降、慢降3个阶段。
5)基于试验建立了考虑火灾高温、冷却方式等影响的UHPC残余强度计算方法,计算结果与试验数据吻合良好。
