Strength properties of autoclaved cellular concrete with high volume fly ash
- Univ. of Pittsburgh, PA (United States). Dept. of Civil and Environmental Engineering
This paper presents the results of an investigation on the strength properties of autoclaved cellular concrete (ACC) blocks, a building material that can contain up to 70% w/w of electric utility fly ash. The scope of this investigation covers three phases: (1) a brief literature review; (2) a selection of optimum strength testing methods suitable for ACC materials; and (3) a determination of physical properties of ACC made with US electric utility fly ash, and comparison of such properties to European ACC materials made with sand as the silica source. Optimum laboratory testing methods were selected based on a comprehensive literature search that included American, European, and Chinese standards. The properties examined were compressive, tensile, and flexural strengths. Results showed that block recipe and density influence the compressive, tensile, and flexural strength values. The investigation indicated that the compressive strength of the blocks increases with dry weight density, and decreases as their moisture content increases.
