BCL-355补偿混凝土收缩膨胀仪使用方法
1、先把纵向限制器放入试模中,然后将混凝土装进试模,再把试模放置在震动台震动表面呈现水泥浆,不泛气泡为止,刮去多余的混凝土抹平然后将试件放置温度为(20±1℃)的标准养护室内进行养护,试件表面用塑料布或湿布覆盖,防止水份蒸发。 当补偿收缩混凝土的抗压强度达到3-5MPa时拆模(般为成型后12-16h)测量试件初始长度。 2、测量3h,将测量仪,标准棒放在测量室内,用标准棒校正测长仪。测量。将测体测头擦净,测量将标记有编号的面朝上,面向测量者,其方向和位置要固定致不得随意变动,使纵向限制器测头与测量仪侧头正确接触,试件测定时间应为规定龄期1h,每试件长度,应反复测量三次取其稳定值。 3、将试件测定初始长度后的试件侵入(20±2℃)的水中养护,分别测定3d、7d、14d的长度然后移入室温为(20±2℃)相对湿度(60±5℃)的恒温恒湿箱内养护分别测定28d、42d的长度上述测长龄期,律从成型日起。 4、每组成型的三个试件,取其算术平均值作为长度变化。计算应精确到小数点后第三位。 BCL-355补偿混凝土收缩膨胀仪 BCL-355补偿混凝土收缩膨胀仪参数规格 1、标准棒长度:L=355 0.02mm 2、测量范围:0-10mm【电子数显】 3、试模规格:100×100×400mm【限制收缩实验】 4、测量精度:0.001mm
