Abstract: To explore the regularity of cement content on concrete performance.Strength, deformability, frost resistance and anti-chemical erosion of concrete were analyzed systematically by experiments with using the same kinds of water binder ratio of a benchmark for the 250 kg/m3, an increase of 50 kg/m3 of 5 different cement content.The results show that under the condition of the same water cement ratio, the frost resistance and anti-chemical erosion of concrete increased with the increase of cement content, but it decreased slightly when the amount of cement content was more than 350 kg/m3; And it has the best performance-price ratio for the strength, deformability, frost resistance and anti-chemical erosion of concrete when cement contents reached around 350 kg/m3.
