Abstract
Cement paste compositions, concrete compositions, and methods of forming the cement paste compositions and concrete compositions are disclosed. Exemplary cement paste compositions and concrete compositions include a water-soluble additive that is dissolved and is configured to perform one or more of ice recrystallization inhibition and dynamic ice shaping when the cement composition is exposed to temperatures less than or equal to a freezing temperature of water.
Claims26
A cement paste composition comprising:
- cement;
- water;
- and
- a water-soluble additive,
- wherein the water-soluble additive in the cement composition is dissolved and is configured to perform one or more of ice recrystallization inhibition and dynamic ice shaping when the cement composition is exposed to temperatures less than or equal to a freezing temperature of water.

A method of forming concrete, the method comprising the steps of:
- mixing an additive in water to form a solution;
- and
- adding cement and aggregate to the solution,
- wherein the additive is configured to perform one or more of ice recrystallization inhibition and dynamic ice shaping when the concrete is exposed to temperatures less than or equal to a freezing temperature of water.
