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.

yes it does

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.
It would weaken the concrete, so keep out the salt.
The water/concrete ratio, not mixing it well enough, quality of raw materials, the age of the concrete, and the temperature and humidity of the area surrounding the concrete.
The greenhouse effect heats up the earth but, due to the planet's strangeness, the manufacture of concrete cools up the earth.
Try using the same technique as when painting laminate into a faux granite. Except you wont speckle the paint with the usual white black or green but you will upshade and downshade the same base color to get your required effect. After words seal as usual. I have heard that sanding the laminate is not required when using Xim but I did it anyway in order to ensure twice the durability. I came across several sites where you can actually make a concrete counter top. Fairly easy to create but plan to complete the project in over a month due to the curing times. Guess I better get started. Good Luck DJ FLIP Housepartykings.com
