Studies on Expansion Properties in Concrete Containing Waste Glass, Silica Fume, Rice Husk Ash and Polypropylene Fibers

摘要

The amount of waste glass sent to landfill has increased over recent years due to an ever growing use of glass products. Landfilling can cause major environmental problems because the glass is not biodegradable material. However, waste glass can be used as fine aggregate, coarse aggregate and powder form in concrete. The fine and coarse aggregate can cause alkali-silica reaction (ASR) in concrete, but the powder form can suppress their ASR tendency and acts as a pozzolanic material. This paper studies the expansion properties in concrete containing waste glass, silica fume, rice husk ash and polypropylene fibers in detail.
