What is the difference between concrete grade and concrete strength?
concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength
What is setting-time?
That varies from mix design to mix design and in highly influenced by the weather (temperature and humidity). Concrete can be made to reach initial set in under and hour, or can be delayed for days if needed. A typical mix on moderate conditions may take a 2 to 3 hours to reach initial set. Initial set is just the first 500 psi... it will continue to hydrate and "set" as long a moister is present. Concrete can continue to gain strength for months, years and even decades (though less and less and time goes on).
What is the intial setting time for cement?
The initial setting time of cement is 30 minutesThe final setting time of the cement is 10 hours.The initial and final setting time of the cement can be found by using the Vicat's apparatus.
How do concrete pumps work?
== == I really wonder how concrete pumps work, liquid (fluid) concrete has a big viscosity, how the pump overcome this big viscosity. I witnessed many times every couple seconds maybe 4-5 seconds the machine emits a loud thump. I think that sound come from pnomatic part of the machine. If anyone know how is it working, I will be glad to hear it, I wish Merry Christmas to all.
Why is fly ash used in construction?
As pozzolan greatly improves the strength and durability of concrete, the use of ash is a key factor in their preservation and add to the concrete's final strength and increase its chemical resistance and durability.It can also increase workability of cement while reducing water demand. The replacement of Portland cement with fly ash also reduces the greenhouse gas foot print of concrete, as the production of one ton of Portland cement produces approximately one ton of CO2. Since the worldwide production of Portland cement is expected to reach nearly 2 billion tons by 2010, replacement of 30% of this amount by fly ash could dramatically reduce global carbon emissions.
What forms instead of dew when temps reach 32 degrees Fahrenheit?
Ice crystals or frost.

Why is grout required?
Grout is used to fill spaces concrete will not flow into. Grout is more watery than concrete and the expectation is that the water will be absorbed into the surrounding materials and the remaining grout will reach design hardness. Concrete, to the contrary, is expected to retain its water and the amount is carefully calculated.
