Center for By-Products Utilization THEORETICAL PREDICTIONS OF ELASTIC PROPERTIES OF CEMENTITIOUS COMPOSITES MADE WITH AND WITHOUT MINERAL ADMIXTURES

This research work was carried out to establish an appropriate theoretical model to describe elastic properties of cementitious composites. The elastic properties include modulus of elasticity, modulus of rigidity, bulk modulus and Poisson's ratio. A literature search was carried out to gain information about existing analytical models in order to predict elastic behavior of composites. Analysi...

Rheology, fiber dispersion, and robust properties of Engineered Cementitious Composites

The capability of processing robust Engineered Cementitious Composites (ECC) materials with consistent mechanical properties is crucial for gaining acceptance of this new construction material in various structural applications. ECC’s tensile strainhardening behavior and magnitude of tensile strain capacity are closely associated with fiber dispersion uniformity, which determines the fiber brid...

Engineered Cementitious Composites

This paper overviews Engineered Cementitious Composites (ECC) as an emerging construction material. Emphasis is placed on the accumulated knowledge on durability, safety, and sustainability of reinforced ECC (R/ECC) structures, recognizing that the concrete of the future must meet these characteristics. In light of recent and future full-scale field applications of ECC, the limited studies on l...

Thermal Properties of Zeolite-Containing Composites

A zeolite (mordenite)-pore-phenol resin composite and a zeolite-pore-shirasu glass composite were fabricated by hot-pressing. Their thermal conductivities were measured by a laser flash method to determine the thermal conductivity of the monolithic zeolite with the proposed mixing rule. The analysis using composites is useful for a zeolite powder with no sinterability to clarify its thermal pro...
