Will snowfall on freshly poured concrete pose a problem?
I need help and reason. Thanks!

It helps us mechanical types enter the civil engineering world. http://www.cement.org/ Check out the bookstore.
Now to answer your question. From what I know it will depend. Adding water to your mixture will weaken it. If the concrete freezes while it is going through its setting phase, the water could expand and break setting concrete. As the chemical reaction of the concrete is exothermic, a small amount of moisture and cold will not hurt. You will have to be more specific with your application, the temperature, etc. to give you a better answer. Also, I am a mech engineer that occasionally dables with concrete so I am probably not the best person to answer you question.

dwedel, was right, if you want more/better information, post more detail.

Snow on a fresh, plastic slab may cause a dilution of the water/cement ratio. This will lower compressive strength and make the concrete less dense and more permeable. Strong durable concrete need to be cured and protected from freezing.
