Experimental study of the performance of C60 pavement concrete
In order to improve the surface standard of the mine heavy vehicle road,on the basis of laboratory studying in C60 concrete,the performance of the C60 concrete in pavement construction will be researched,and frost resistance,carbonation resistance and creep performance variation were analyzed.The results showed that mixed with silicon powder and slag powder,under the condition of lower amount of cement,The test of C60 pavement concrete structural compactness,mechanical properties and durability indicators could satisfy the design requirements; As the number of freeze-thaw cycles went up,the rate of strength loss and mass loss of the test pavement concrete increased linearly; The carbonized value increased significantly,in 7 days; growthed significantly slowed in the range of 7 days-28 days; The creep strain value increased linearly during the period of 100 days,changes leveling off after more than 100 days of age,and creep strain values stabilized.
