采用温水养护方法,提高混凝土的早期强度,就其作用原理来讲,并没有改变水泥硬化的条件,因此是比较合理的。从这一认识出发,我们对温水养护混凝土预测强度与标准强度的相关性进行了试验研究。一、试验情况首先,我们对温水养护的水温和恒温时间进行了探索性试验。试验结果表明,水温70℃,恒温时间12小时,是混凝土强度增长快慢的条件界限。考虑到设备保温要力求简
The use of warm water conservation methods to improve the early strength of concrete, in terms of its principle of action, does not change the conditions for cement hardening, so it is more reasonable. Starting from this understanding, we conducted a pilot study on the correlation between predicted strength and standard strength of warm water concrete. First, the test situation First of all, we conducted an exploratory experiment on the water temperature and constant temperature time for warm water conservation. The test results show that the water temperature is 70°C and the constant temperature time is 12 hours, which is the condition boundary for the strength of concrete to increase. Taking into account the equipment insulation to strive for simplicity
