Study on the strength of sea sand concrete introduced by chloride ions

In sea sand by the determination of free chlorine ions to study the chloride ion to the strength of sand concrete. Experimental data show that between 0% to 0.1% chloride ion content of sea sand concrete strength comparison between the value of a group that is found in 20% of fly ash were mixed with 3 days flexural strength is increased with the concentration of chloride ion Rise, the other group had no obvious rule, dilute the sand and did not play down the comparison that does not dilute the sand sea sand either 3 days or 28 days strength values are higher than the desalination of sea sand, the presence of chloride ions in sea sand Early strength has a positive role in promoting.
