本实验进行了矽酸盐水泥在各种情况下减缩作用-抗压强度-抗折强度之间关系的研究,包括水泥的品种不同、标号不同、以及同一水泥而细度不同或养护温度不同等情况。 实验结果证明:就发展速度而言,前期抗折大于抗压,后期抗压大于抗折,而减缩作用则总是处于二者之间。就具有同一强度时之减缩量而言,则水泥愈细,减缩愈少,而养护温度较高者,减缩亦较多。
In this experiment, the relationship between shrinkage-compressive strength and flexural strength of citrate cement in various situations was studied, including different types of cement, different labels, and the same cement with different fineness or different maintenance temperatures. Happening. The experimental results show that: As far as the development speed is concerned, the pre-resistance is greater than the compression resistance, the later-stage compression is greater than the flexion resistance, and the reduction effect is always in between the two. With respect to the amount of reduction with the same strength, the finer the cement, the smaller the shrinkage, and the higher the curing temperature, the more reduction.
