粉煤灰加气混凝土吸水性能研究

Water absorptivity capacity for the fly ash aerated concrete

试验表明，当粉煤灰加气混凝土在整体吸水时的吸水速度和吸水量明显大于粘土砖；粉煤灰加气混凝土一端吸水时的吸水性能与其成型时的膨胀方向密切相关，当吸水方向平行于加气混凝土膨胀方向时，粉煤灰加气混凝土的吸水速度和吸水量明显大于粘土砖；吸水方向垂直于加气混凝土膨胀方向时，粉煤灰加气混凝土的吸水速度和吸水量小于粘土砖。

When the whole specimen is absorbing water, the absorbing speed and weight of the fly ash aerated concrete is much larger than common sintered clay brick. When the specimen is absorbing water from one side, the absorptive capacity for water of the fly ash aerated concrete is related with expanded direction. When the direction of absorbing water paralleled to expanded direction, the absorbing water speed and weight of the fly ash aerated concrete is much larger than common sintered clay brick. When the direction of absorbing water is upright to expanded direction, the absorbing-water speed and weight of the fly ash aerated concrete is less than common sintered clay brick.
