Effects of Temperature on concrete Compressive Strength during curing time.

What is Curing of Concrete??
  • Curing is a process during which a chemical reaction (such as polymerization) or physical action (such as evaporation) takes place,
  • resulting in a harder, tougher or more stable linkage (such as an adhesive bond) or substance (such as concrete)
  • Why do Concrete Comprehensive Strength Testing required to be Tested at 28 days??

  Concrete gain 60 %  -65% of specified strength in 7 days
  And 90% of Specified Compressive Strength in 28 days.
  So,It is recommended as per IS 456 -2000 to Test verification of Strength of concrete as mentioned above at 7 days & 28 days respectively to checking the variations limit of strengths.


We should do proper curing by considering the environmental conditions, type of structural members, atmospheric temperature ??
Maintaining the proper temperature also plays a vital role in concrete as mentioned, it should not be colder than 50C. Concrete is kept moist for at least 28 days.
Recommended to set a maximum limit between 26.7°C and 35°C.

How the Internet works around you

  How the Internet works around you? 1. How the Internet works around you Who invented Internet Work? Scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system referred to as the Internet. 2. How do internet starts first at beginning? The internet began as ARPANET, an academic research network that was funded by the military's Advanced Research Projects Agency (ARPA, now DARPA). These standards, known as TCP/IP, became the foundation of the modern internet. ARPANET switched to using TCP/IP on January 1, 1983. 3.Where is Internet Located? Today, the internet is? Basically housed in the data centers located in the Washington-area suburb, which is the biggest data center market in the world. “The internet itself is really comprised of these peering points that are housed inside data centers. Even though the Internet is still a young technology, it's hard to imagine life without it now.  Every year, engineers cr
