C++ has a much larger library than C and some things may be automatically linked in by C++ when they are not with C For instance if you're used to using g++ for math-heavy computations then it may come as a shock that when you are using gcc to compile C you need to explicitly include the math library for things like sin or even sqrt

With these approaches the required difference between specified and targeted w/c depends on (1) the permitted probability of w/c exceeding a specified value and (2) the vari-ability in w/c as indicated by standard deviation In our experience on well-controlled jobs the standard devia-tion of w/c for ready mixed concrete is about 0 02 to 0 03
"Comparison of Class C Versus Class F Fly Ash for Concrete Pavement" Wisconsin Highway Research Program Results • The two Class C ash sources had a very low LOI (0 2 percent and 0 3 percent) but the ash with the lower LOI had the second highest adsorption capacity of the four ash sources tested (two Class C and two Class F)
In the presence of water Class C fly ash will harden and gain strength over time Class C fly ash generally contains more than 20% lime (CaO) Unlike Class F self-cementing Class C fly ash does not require an activator Alkali and sulfate (SO4) contents are generally higher in Class C fly ashes
