Experiment 1
Premixing mortar in Example 3 adds water that mortar A is made, and the concrete column A of diameter 30cm is then made, wherein should
The center of concrete column A is inlaid with K-type thermometric line.It is small every 1 by K-type thermometric line during mortar A maintains into concrete column A
When measure a concrete column A centre temperature, be recorded as T1.
Experiment 2
It will be by 110Kg cement, 18Kg densification powder, the coloured slag of 26Kg, 5.6Kg methyl cellulose ether, 1Kg water-reducing agent, 8Kg
Gypsum is stirred to obtain control mortar；Add water that mortar B is made in control mortar, the concrete column B of diameter 30cm be then made,
In, the center of the concrete column is inlaid with K-type thermometric line.During mortar B maintains into concrete column B, by K-type thermometric line every
The temperature of the concrete column B centre of measurement in 1 hour, is recorded as T2.
In the above-described embodiments, it is conserving in the identical time, the value of T1 is smaller than T2 value；The temperature difference between T1 and T2 is
T, at first 3 days of maintenance, the maximum value of t was 21 DEG C；At the 3rd~7 day of maintenance, the maximum value of t was 17 DEG C；The 7th of maintenance the
~14 days, the maximum value of t was 13 DEG C.Since, that sustained release heat absorbent is not added, this makes concrete column B in curing period in control mortar
