摘要：研究了陶粒取代率和耐碱玻璃纤维（耐碱玻纤）体积掺量对陶粒混凝土抗压强度、比强度和弹性模量的影响。结果表明，耐碱玻纤陶粒混凝土的抗压强度、比强度和弹性模量均随着陶粒取代率的增加而降低，当取代率达到20%后下降趋势更加显著。随着耐碱玻纤掺量的增加，陶粒混凝土的各项指标均呈先增大后减小趋势；当陶粒取代率在20%以内时，不同掺量耐碱玻纤陶粒混凝土的比强度均优于普通混凝土；当陶粒取代率为15%、耐碱玻纤掺量为0.3%时，比强度最优。 Abstract: The effects of the replacement rate of ceramsite and the volume content of alkali resistant glass fiber on the compressive strength, specific strength and elastic modulus of ceramsite concrete were studied. The results show that the compressive strength, specific strength and elastic modulus of alkali resistant glass fiber ceramsite concrete decrease with the increase of ceramsite replacement rate, and the decrease is more significant when the replacement rate reaches 20%. With the increase of alkali resistant glass fiber content, the indexes of ceramsite concrete increase first and then decrease. When the replacement rate of ceramsite is within 20%, the specific strength of alkali resistant glass fiber ceramsite concrete with different contents is better than that of ordinary concrete. When the replacement rate of ceramsite is 15% and the fiber content is 0.3%, the specific strength reaches the best state.

摘要：研究了不同体积掺量的钢纤维和PVA纤维对不同碳化龄期下钢-PVA混杂纤维高韧性混凝土的抗碳化性能以及碳化后力学性能的影响，考虑了水泥、粉煤灰、碳化等多因素效应和纤维体积分数对混凝土碳化深度的影响，并提出了钢-PVA混杂纤维高韧性混凝土碳化深度预测模型。结果表明：纤维的掺入提高了混凝土强度及抗碳化性能，且1.0%钢纤维与0.10%PVA纤维的混掺效果最好；提出的碳化预测模型精度较高，可为混凝土碳化深度的预测提供参考。 Abstract: The effects of different volume of steel fiber and PVA fiber on the carbonization resistance and mechanical properties of steel-PVA hybrid fiber high toughness concrete under different carbonization ages were studied. Considering the multi-factor effects such as cemen, fly ash, carbonization and fiber volume fraction on the carbonization depth of concrete, a carbonization depth prediction model for steel-PVA hybrid fiber high toughness concrete was put forward. The results show that the incorporation of fibers improves the strength and carbonization resistance of concrete, and 1.0% steel fiber and 0.10% PVA fiber have the best blending effect. The carbonization depth prediction model has high accuracy and can provide a reference for the prediction of concrete carbonization depth.

摘要：通过抗压强度、劈裂抗拉强度、质量腐蚀系数和强度腐蚀系数试验，研究了硅粉/混杂纤维水泥基材料的力学性能和耐硫酸盐腐蚀性能。结果表明：硅粉/混杂纤维水泥基材料的强度均高于空白组和单掺纤维水泥基材料强度；当硅粉掺量为8％、玄武岩纤维掺量为0.15％、聚丙烯纤维掺量为0.50％时，硅粉/混杂纤维水泥基材料的质量腐蚀系数和强度腐蚀系数最小，即耐腐蚀能力最好。 Abstract: Through the compressive strength, split tensile strength, mass corrosion coefficient and strength corrosion coefficient test, the mechanical properties and sulfate corrosion resistance of silica fume/hybrid fiber cement-based materials were studied. The results show that the strength of silica fume/hybrid fiber cement-based materials is higher than those of blank group and single fiber cement-based materials. When the content of silica fume is 8%, the content of basalt fiber is 0.15% and the content of polypropylene fiber is 0.50%, the mass corrosion coefficient and strength corrosion coefficient are the smallest, that is, the corrosion resistance of silica fume/hybrid fiber cement-based materials is the best.
