研究了不同熟料矿物含量的水泥对配制混凝土抗疲劳、抗冲击和耐磨性能的影响。结果表明,当熟料中硅酸盐矿物C2S、C3S含量接近时,随着熟料中Fe2O3含量的增加,C4AF含量增加,C3A含量降低,所配制混凝土在28d和90d龄期的抗疲劳、抗冲击和耐磨性能都依次提高;在保证熟料中适量C3S满足强度要求和熔剂矿物C3A、C4AF含量接近的前提下,低C3S高C2S含量的水泥配制的混凝土抗疲劳、抗冲击和耐磨性能都优于高C3S低C2S含量的水泥配制的混凝土。即:在保证足够C3S含量满足强度要求、熔剂矿物含量为19%～20%时,适当提高C4AF和C2S含量对提高混凝土的上述性能是有益的。
The effect of cement with different clinker mineral content on fatigue, impact resistance and wear resistance of concrete was studied. The results show that when the C2S and C3S contents of silicate minerals in clinker are close, with the increase of Fe2O3 content in clinker, the content of C4AF increases and the content of C3A decreases. The fatigue resistance and anti-fatigue of the prepared concrete at 28d and 90d Impact and abrasion resistance of cement prepared from concrete with low C3S and high C2S content, while ensuring that the appropriate amount of C3S in the clinker meets the strength requirements and the flux minerals C3A and C4AF are close to each other Are better than the high C3S low C2S content of concrete formulated concrete. That is, it is beneficial to improve the above properties of concrete by properly increasing the content of C4AF and C2S while ensuring that the sufficient C3S content meets the strength requirement and the flux mineral content is 19% -20%.
