摘要

Coal fly ash (CFA), as a by-product generated from coal fired power stations, is widely used for autoclaved concrete block production. It has been found that the generation of tobermorite is great benefit to the block strength during autoclaving. In this study, the tobermorite fibers synthesized from CFA and lime via the hydrothermal process are used as the revulsive to promote the mechanic strength of the concrete blocks. The results show that tobermorite fibers with 0.01-0.5 μm in diameter and 1-3 μm in length are obtained at 200°C for 0.2 h. As the addition of prepared tobermorite fibers increases from 0 wt% to 2.0 wt%, the compression strength of concrete block increases from 24.6 to 40.5 MPa, and the compression strength of aerated concrete block produced under the optimized conditions can reach above 7.5 MPa.
