First of all, after the cement enters the concrete mixing or construction site, it must be tested according to the required test items, paying special attention to the water demand of the cement. If necessary, the concrete mix should be re-made according to the actual situation. than test. Secondly, while ensuring that the water-cement ratio of the concrete remains unchanged, the amount of water-reducing agent used during concrete mixing should be appropriately adjusted. Third, on the basis of ensuring the strength of concrete, increase the proportion of fly ash in concrete mixing. Finally, add appropriate amounts of fly ash I and II to control the segregation of concrete and improve the workability of concrete. </p
