Effect of Different Mineral Admixtures on the Dry Shrinkage and Mechanical Properties of Mortar

In this paper, the effects of four different mineral ginseng materials on the mechanical properties of mortar were studied, and the results showed that high territory, fly ash, and silica fume had an inhibitory effect on the drying shrinkage of mortar, and mineral powder increased the drying shrinkage of mortar. The high territory in the mineral admixture has the best effect on the inhibition of mortar drying shrinkage. The compressive strength and flexural strength of the mortar can be improved by adding a certain amount of mineral admixture, which increases the compressive strength by about 20%-40% and the flexural strength by about 20%-30% compared with the control group, and the improvement effect difference between different components is not large.
