Title: Examining short & long term properties of self-consolidating concrete (SCC)
Description: This report provides the results of a research study requested by New Mexico Department of Transportation (NMDOT) and conducted by University of New Mexico. The research team examined developing and characterizing self-consolidating concrete (SCC) produced using local New Mexico materials. It also includes a brief review on the state of the art of SCC. Five SCC mixes were produced using local New Mexico aggregate from two sources in New Mexico. SCC mixes are compared to normal vibrated concrete (NVC) mixes typically used in NMDOT highway projects and they were produced using the same local aggregate. Mix designs of the SCC and NVC mixes are described in detail. The plastic properties of fresh concrete are reported and discussed. Complete details on all strength and durability characteristics of SCC examined up to one year of age are discussed. The strength characteristics include compressive and flexural strength and static and dynamic modulus of elasticity. Creep and shrinkage of SCC are also studied as well as durability properties including chloride ion resistance, freeze-thaw durability, and the potential for alkali-silica reaction (ASR). The report concludes with a suggested implementation plan for using SCC in highway projects in New Mexico.
