JHX-1集料碱活性养护箱工作原理
试件成型完毕后,带模放入标准养护室,养护24h±4h后脱模。脱模。后立即测量试件的长度 ,此长度为试件的基准长度。测长应在20℃±2℃的恒温室中进行。每个试件至少重复测试两次,取差值在仪器精密度范围内的2个读数的平均值作为长度测定值。待测的试件须用湿布覆盖,以防止水分蒸发。测长后将试件放入养护筒中,筒壁衬以吸水纸使筒内空气为水饱和蒸气,盖严筒盖放入38℃±2℃养护室(箱)里养护(个筒壁的试件品种应相同)。测长龄期自测基长后算其分14d、1、2、3、6、9、12个月几个龄期,如有必要还可以适当延长。在测长的天,应把养护筒从38℃±2℃养护室(箱)中取出,放入20℃±2℃的恒温室。试件的测长方法与测基长时相同,每个龄期测长完毕后,应将试件放入养护筒中,盖好筒盖,放回38℃±2℃养护室(箱)中继续养护到下个测试龄期。 测长时应观察试件的变形、裂缝、渗出物,特别要注意有无胶体物质出现,并作详细记录。 JHX-1集料碱活性养护箱参数规格
