Mechanical Properties and Micro Structure of Cement Concrete in Freeze-Thaw Environment

In order to find the declay law of mechanical property and performance difference after salty water fresh freeze-thaw cycle, cycle environments under are simulated. The compressive strength, dynamic elastic modulus mass lost tested. pore structure parameters also tested by MIP. Plot diameter distribution curve. result shows that strength all decreased. degree these two properties decreasing freeze thaw recycle is more than one water. porosity critical become larger. amount pores whose between 100nm 1000nm increase. decrease. deteriorate deeper in
