Silpozz Micro silica can slightly delay the setting time of concrete, but this can be adjusted with admixtures to meet project needs.
Setting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture. Hardening
it is 120 minutes
you can buy primers from you local hardware or diy store to extend setting time
Initial Setting time can be extended by adding retarders during mixing of concrete. Sugar solution is the easily available retarder.

put less water
The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
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
Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours
The construction industry uses both the natural and the synthetic forms of gypsum in Portland cement manufacturing. Although the amount of gypsum used in the mix represents a small percentage of the volume of all ingredients, gypsum has important functions.
The liquid content temperature its concentration and the area's environment being concreted
Rust can weaken the steel reinforcement inside concrete structures, leading to cracks and structural damage over time. This can compromise the durability and stability of the concrete structure.
