文章摘要:
一、混凝土配合比
 
在本工程中我们起初设计的混凝土配合比,强度与工作性能均满足要求,但是在浇筑试验柱时,发现振捣以后混凝土表面浮浆较多,拆模以后外观表面比较粗糙,有麻面现象,分析其原因主要是由于混凝土本身有泌水现象,在现场浇筑时由于混凝土体积较大泌水较多,经振捣以后发生离析所造成的,这种情况在我们进行混凝土配合比设计试拌时,由于试验时拌和的混凝土体积较小,所以无法准确地判断推测出来。为了节省材料,同时能够查出影响外观的所有原因,我们制作了四套钢模板,做了大量的小型试验柱,这些试验柱的尺寸为20cm*20cm*150cm,经过试验发现这些小型试验柱的外观较真实地反映了现场混凝土的外观情况。以此为手段,我们在多方面分析原因的基础上,对原来的配合比进行了调整,并制作了三十余棵小型试验柱来考查调整的效果。
