Example Embodiment
[0012] Example 1:
[0013] A concrete with high resistance to carbonization. The raw material components are calculated in parts by weight: 100 parts of cement, 25 parts of fly ash, 15 parts of kaolin, 12 parts of slag powder, 15.5 parts of coarse aggregate, 7 parts of quartz sand, polycarboxylic acid 4 parts of water reducing agent. The coarse aggregate is slag powder obtained after limestone ore is crushed.
Example Embodiment
[0014] Example 2:
[0015] A concrete with high resistance to carbonization. The raw material components are calculated in parts by weight: 100 parts of cement, 15 parts of fly ash, 40 parts of kaolin, 10 parts of slag powder, 25 parts of coarse aggregate, 2 parts of quartz sand, polycarboxylic acid 7 parts of water reducing agent. The coarse aggregate is slag powder obtained after limestone ore is crushed.
