Fly Ash, Slag, Silica Fume, and Rice Husk Ash in Concrete: A Review
1993年4月1日 · Some of the most promising substitutes or supplementary cementing materials are high- and low-calcium fly ashes, ferrous and nonferrous slags, condensed silica fume, and rice husk ash. This paper presents a review on the use of these by-products in concrete.
Mechanical Properties of Three High-Strength Concretes …
1995年3月1日 · Three high-strength concretes containing silica fume were cast and tested at the University of Alberta to study the mechanical properties. The concretes were designed to have compressive cylinder strengths of 60, 90, and 120 MPa. The tests carried out included the compressive cylinder split-cylinder notched-beam, and triaxial compression tests.
1) Understand the cement-silica fume (SF) mixtures particle packing behavior and hydration kinetics through SF dissolution kinetics in cementitious mixtures and their comparison to simulation models. 2) Accurate simulation of the hydration reaction and the microstructure development of cement-SF blends in UHPC.

Cryogenic Frost Resistance of Lightweight Concrete Containing …
DOI: 10.14359/2465. Date: 5/1/1989. Abstract: Longitudinal thermal strains of high-strength, air-entrained, lightweight concrete containing silica fume were monitored during a single frost cycle between 15 and -157 C to measure the coefficients of thermal length changes at different temperatures. The immunity of such concrete to repeated ...
