纤维素纤维对水工混凝土绝热温升影响的试验研究

Experimental study of the influence of cellulose fiber on hydraulic concrete adiabatic temperature rise

通过对纤维素纤维水工混凝土绝热温升的试验研究,探讨了纤维素纤维对水工混凝土水化热的影响。结果表明:纤维素纤维在水工混凝土中能降低1 d时间前的绝热温升,升高了1 d后的绝热温升,随着混凝土中纤维素纤维掺量的增加,更能够增加这个趋势。加入纤维素纤维后再加入致密剂,能够降低水工混凝土1 d后绝热温升值。

This article discusses the influence of the cellulose fiber on hydraulic concrete hydration heat through cellulose fiber hydraulic concrete adiabatic temperature rise experimental study. The results show that the cellulose fiber in hydraulic concrete can reduce the adiabatic temperature rise one day before and increased adiabatic temperature rise one day after. With the increasing content of cellulose fiber in the concrete,the trend increases more. Mixing the dense agent with cellulose fiber can reduce hydraulic concrete adiabatic temperature rise after one day.
