Clearly, plenty of excess cement milling capacity is needed in order to "catch up" after such interruptions. Control of product quality. In addition to control of temperature (mentioned above), the main requirement is to obtain a consistent fineness of the product. From the earliest times, fineness was measured by sieving the cement. As cements have become …

Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. Water spray is controlled with mill outlet gas or material temperature. A hardware interlock is recommended with mill main drive to avoid accidental spray in mill.

Mar 23, 2018· Generally, a concrete temperature is limited to 160°F (70°C) during hydration. If the temperature of the concrete during hydration is too high, it will cause the concrete to have high early strength development but consequently gain less strength in the later stage, resulting in lower durability of the structure overall.

Mar 01, 1980· By the age of 28 days the high-temperature concretes were weaker than the 73° concrete. From 28 days to 1 year the 55° concrete was considerably stronger than the 73° concrete. From 90 days onward the 40° concrete was stronger than the 73° concrete and the 25° concrete was slightly stronger than the 73° concrete.

Answer (1 of 6): The answer is not what temp it is outside, it's what temp you can keep the concrete at!! Water starts to expand at 4 degrees Celsius. That's when it's at it's densest. Hence there could be ice covering the lack but the very bottom will be 4 degrees. (Freshwater). That being said ...

Concrete cures best in a range between 70° to 80° F., but as your temperature approaches 90° F, you'll start to run into problems. In the world of concrete, hot weather is more than just temperature. Days of low relative humidity, as well as days with high wind speeds, also are grouped into "hot weather," and can cause problems with pouring ...

Typical specifications require the temperature of the concrete during placement to be within a range of 10°C to 32°C. However, different specified limits are provided depending on the element size and ambient conditions (ACI 301, 207). The temperature the concrete exhibits during placement affects the temperature of concrete during the next ...
