近年来,为了提高水泥电杆的质量,人们从提高混凝土质量入手,采取一些工艺措施,获得较好的效果。一、拌制低流动度混凝土对于离心混凝土,水灰比过大,更易产生离析分层,降低强度。同时,离心过程中排出的水泥浆也多,致使很大一部分水泥损失掉。当离心速度偏低时,也易出现坍方或空鼓等质量问题。我厂采用低流动度混凝土(坍落度一般为1～3厘米)制作的电杆在离心成型时内壁很少聚积水泥浆,内外表面都很光滑,也无
In recent years, in order to improve the quality of cement poles, people started by improving the quality of concrete and adopted some technological measures to obtain better results. First, mixing low-flow concrete For centrifugal concrete, the water-cement ratio is too large, and it is easier to produce segregation and reduce the strength. At the same time, more cement slurry was discharged during the centrifugation process, resulting in the loss of a large part of the cement. When the centrifugal speed is low, quality problems such as flooding or empty drums are also likely to occur. Our factory uses low-fluidity concrete (slump is usually 1 to 3 cm) made by the pole when the centrifugal molding is rarely accumulated in the inner wall of cement slurry, both inside and outside the surface is smooth, nor
