DURABLE CONCRETE AND METHOD FOR PRODUCING THE SAME

摘要

A concrete mix for producing freeze-thaw durable concrete having enhanced strength properties, like compressive strength, abrasion resistance, impact strength, toughness, is disclosed. The novel concrete mix contains deformable solid elements in place of 4-8% entrained air for good durability of concrete under freeze-thaw cycles.

主权项

1. A hardened concrete resistant to cracking in a freeze-thaw environment, comprising the following components:
cement; aggregates; admixtures; and deformable solid elements, wherein the total volume of said deformable solid elements is sufficient to accommodate expansion caused by water freezing in capillary pores of said hardened concrete during a freezing event, and the maximum dimension of said deformable solid elements is less than about 300 micrometers, said hardened concrete having a density above about 1.5 g/cm3.
