Among them,the complicated sandstone are are mostly cement fracture and fracture. Amongst them, resulting from because of the complicated composition on the cementitious supplies, they had been more susceptible to low mineral mineral composition from the cementitious supplies, they have been much more susceptible temperature. Therefore, below the double action of dynamic load load and low temperto low temperature. For that reason, below the double action of dynamicand low temperatures, it was it was discovered that the harm occurred at the cementitious materials 1st, and after that atures, discovered that the harm occurred at the cementitious supplies 1st, after which brought on the fracture on the of sandstone as a whole. caused the fracturered the red sandstone as a entire.five. Discussion 5. Discussion five.1. Influence of Water-Ice Phase Transformation on Dynamic (-)-Irofulven Inducer strength of Red Sandstone five.1. Influence of Water-Ice Phase Transformation on Dynamic Strength of Red Sandstone In accordance with the comparison of Figures 3 and 9, it really is located that as the temperature In accordance with the comparison of Figures 3 and 9, it can be discovered that because the temperature drops to damaging values, the dynamic compressive strength with the two red sandstones drops to adverse values, the dynamic compressive strength of your two red sandstones in in the comparison group increases below cold contraction, but there’s a significant distinction the comparison group increases under cold contraction, but there’s a huge distinction bebetween them. The dynamic compressive strength of the dry red sandstone increases tween them. The dynamic compressive strength on the dry red sandstone increases by by 14 , when that of the water-saturated red sandstone only increases by 4 , with a 14 , when that on the water-saturated red sandstone only increases by four , having a differdifference of ten . As a result, it may be inferred that water-ice phase transformation features a ence of ten . As a result, it could be inferred that water-ice phase transformation includes a particular particular degree of deterioration effect inside the strength of saturated rock below high strain degree of deterioration effect inside the strength of saturated rock below higher strain price conrate circumstances. ditions.Minerals 2021, 11, x FOR PEER Critique Minerals 2021, 11,11.
