Summary: | Under the condition of low temperature 5 ℃, five kinds of early strength agents were combined with polycarboxylic acid admixture to explore the effect of the mixed early strength polycarboxylic acid superplasticizer on the low temperature early strength. The results show that the composite early strength polycarboxylic acid superplasticizer has a good low temperature early strength enhancement performance. Among them, NaNO2 compound modification, compared with other early strength agents after the compound effect, has a better low temperature early strength enhancement performance advantage. |
