养护温度对矿物掺合料活性指数影响的试验研究
Experimental Study on the Effect of Curing Temperature on the Activity Index of Mineral Admixtures
摘要
Abstract
The absolute activity index and relative activity index of fly ash and slag were measured under the condition of standard curing ( 20 ℃) and low and negative temperature ( 10 ℃、5 ℃、 -3 ℃) curing , the effect of curing temperature on the activity index of fly ash and slag was analyzed .The results show that the absolute activity value of fly ash decreases with the decrease of curing temperature before 7 d of age, after 7 d of age, with the decrease of curing temperature , it increases firstly and then decreases;The absolute activity value of slag decreased with the decrease of curing temperature before 3 d of age, after 3 d of age, with the decrease of curing temperature , it increases firstly and then decreases .With the increase of age , the absolute activity index of fly ash changed little under the condition of standard curing , and increases in low and negative temperature curing , the absolute activity value of slag increases with age .At the same age , the relative activity of fly ash and slag decreases with the decrease of temperature;With the growth of age , the relative activity value of fly ash changed little under the condition of standard curing , and gradually increased at low and negative temperature; The relative activity of the mineral powder increases with age .关键词
