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...
متن کاملHygral Behavior of Engineered Cementitious Composites (ECC)
In this paper, the sorption isotherm and the hygral deformation of a tensile strain-hardening fiber reinforced engineered cementitious composite (ECC) is described using a physical model. The influence of using a low alkali content Portland cement on the physical mechanisms of drying shrinkage is discussed. From a durability point of view the crack width of a material as a result of restrained ...
متن کاملCenter for By-Products Utilization SUPERPLASTICIZES STRUCTUREAL CONCRETE CONTAINING HIGH VOLUMES OF CLASS C FLY ASH
This research is conducted with a view to investigate performance of concrete containing high volumes of ASTM Class C fly ash. A portland cement concrete, proportioned to have 28-day compressive strength of 6,000 psi (41 N4Pa) is used in this study. Concrete mixes are also proportioned to have various levels of cement replacement by fly ash ranging from 40% to 70% by weight. Concrete performanc...
متن کاملAn Experimental Study on Utilization of Slag and Fly Ash as an Alternative Cementitious Binder
This study investigates the utilization of slag and fly ash (FA) as alternative cementitious binder. Combination of 60% slag and 40% FA was used as new binder. In addition, for activation of slag and FA, sodium hydroxide and calcium hydroxide was used as a chemical activator by 5% weight of the binder, separately. Water to binder and sand to binder ratios was kept 0.55 and 3 in mortar preparati...
متن کاملGeneral Design Assumptions for Engineered Cementitious Composites
The use of Engineered Cementitious Composites (ECC) for structural design requires a number of assumptions of the material, some of which can be drastically different from those suitable for normal concrete and tension-softening fiber reinforced concrete. This contribution focuses on design assumptions of the constitutive models of ECC in tension and compression. Specifically, while the tensile...
