为了探究玻璃纤维掺量、玻璃纤维长度和陶粒对混凝土力学性能的影响,配制玻璃纤维增强混凝土(GFRC),采用响应面法和中心复合表面设计探究单因素间交互作用对GFRC性能的影响.结果表明:单因素对混凝土抗压强度响应显著程度依次为陶粒取代率＞玻璃纤维掺量＞玻璃纤维长度,双因素交互作用下显著程度为玻璃纤维长度和玻璃纤维掺量＞陶粒取代率和玻璃纤维掺量＞陶粒取代率和玻璃纤维长度;GFRC最优配合比组合为陶粒取代率为10.6％,玻璃纤维长度为14.4 mm,玻璃纤维掺量为0.59％时,预测抗压强度最高为48.5 MPa,与实测平均值相差仅0.2 MPa.该成果有助于GRFC的推广使用,也为此提供了优化配合比设计和参考试...

To explore the effects of content of glass fiber,length of glass fiber,and ceramsite on the mechanical properties of concrete,glass fiber reinforced concrete(GFRC)was formulated,and the response surface method with the central composite face-centered design(CCF)were used to explore the effect of single factor interactions on GFRC performance.The results show that the significant degree of response of single factor to the compressive strength of concrete is ceramsite substitution rate＞glass fiber content＞glass fiber length,and the degree of gl...
