绿色高性能纤维增强水泥基复合材料GHPFRCC(Green High-performance Fiber-reinforced Cementitious Composites Column)以工业废料粉煤灰代替水泥、PVA(Polyvinyl Alcohol)纤维等为主要原料配制而成
能够大大改善结构耗能能力和耐久性。对16组GHPFRCC试件(尺寸为70.7mm×70.7mm×213.8mm)进行静力受压试验
研究分析GHPFRCC棱柱体轴心抗压强度和弹性模量的影响因素及规律。试验结果表明:①水灰比对抗压强度的影响最大
要提高GHPFRCC抗压强度需减小水灰比;②对GHPFRCC弹性模量影响最大的因素为水灰比
砂胶比影响最小;③GHPFRCC抗压强度大小与普通混凝土相似
说明粉煤灰替代水泥没有明显降低其抗压强度;④由于含有PVA纤维和不含粗骨料
GHPFRCC弹性模量略低于普通混凝土;⑤给出了GHPFRCC抗压强度和弹性模量之间的数值表达式。
A lot of non-renewable resources are consumed during concrete production
and this is not in accord with the requirement of sustainable development in China.The fly ash and polyvinyl alcohol(PVA)fiber are used to develop a new green building material
the green high-performance fiber-reinforced cementitious composites(GHPFRCC).The GHPFRCC can promote the structural sustainability by controlling the crack width and simultaneously reduce the energy consumption of structure.This paper reports the development of GHPFRCC with high volumes of fly ash and PVA fiber
and emphasizes the axial compressive strength and elastic modulus of GHPFRCC based on the static compressive test.There are 16-group specimens with sectional size of 70.7mm×70.7mm and height of 213.8mm.Experimental results show that:(1)to improve the compressive strength of GHPFRCC
it needs to decrease water cement ratio
which is the biggest influencing factor;(2)the biggest influencing factor on elastic modulus is water cement ratio
and the least is sand-binder ratio;(3)the prism axial compressive strength of GHPFRCC is similar to concrete
it indicates that the existence of fly ash did not reduce the compressive strength obviously;(4)the elastic modulus of GHPFRCC is typically lower than concrete due to the existence of PVA and the absence of coarse aggregate;(5)the fitting relationship of elastic modulus and compressive strength is put forward.
