proper compaction and proper curing of the concrete gives good concrete. for compaction, it lessen the air voids or micro space between the aggregates of the concrete, those voids are very little which is not really visible. for curing, it lessen the heat of hydration of the cement.

Consider what marble powder is. It is basically calcite, which is an already common component of concrete. Adding more would be to increase the ratio of calcium carbonate to other plasticizing materials. In effect, it would make the concrete more stony and brittle.

Adding sugar to concrete can help to improve workability and slow down the setting time. However, it can also reduce the strength and durability of the concrete in the long run due to potential issues with carbonation and decreased bonding between cement particles. Overall, it is not recommended to use sugar as an additive in concrete unless in specific situations where these effects are desired.
Generally, if concrete splits in freezing temperatures, it is because Water got into cracks and froze. The expansion of the ICE in the cracks would force the cracks open even farther and possibly split the concrete.

So long as the concrete is fully cured, ice won't hurt it in your lifetime.If it's not fully set, you'll need to keep it covered with an insulating blanket until all the water has evaporated and it looks dry (light gray}Concrete generates heat as it cures so all you'll need is a blanket this time of year.If it gets down into the teens, you'll need to put additives in the concrete and add a heat source to aid in the curing.
Insufficient cement in a concrete mix can lead to reduced strength and durability of the final product. The concrete may become more porous, making it susceptible to water infiltration and freeze-thaw damage. Additionally, the bonding between aggregates may be weak, resulting in increased risk of cracking and failure over time. Overall, inadequate cement compromises the structural integrity and longevity of the concrete.
It would weaken the concrete, so keep out the salt.
