水泥混凝土上要用该公式进行换算，用该公式换算为GB/T 14685-2001中压力为200KN的压碎值，400KN是用于沥青混凝土路面用碎石或二灰碎石基层中压碎值所用的最大压力èD¯n§^5ãbbs.3c3t.com_ÐõTã
G5
lllliiiiuuuujun - 2008/5/5 16:54:00
就是用JTG E42-2005中压碎值试验方法（40KN）所得结果*0.816-5，即可换算为GB/T 14685-2001试验方法所得压碎值èD¯n§^5ãbbs.3c3t.com_ÐõTã

fuzhengjun - 2008/5/8 17:39:00
Y=0.816*16.8-5 = 8.7%是对的，如果按Y=0.816*0.168-5 = -4.86%，不成立的。计算时只去掉%就行，不必换算成0.168，否则就不对了。èD¯n§^5ãbbs.3c3t.com_ÐõTã

这个正确，Y=0.816*16.8-5 = 8.7%，只要是集料试验就要换算。èD¯n§^5ãbbs.3c3t.com_ÐõTã

只要是水泥混凝土都要换算 还分什么桥梁吗。。。木头的桥梁不用。。。X指的就是你算出的压碎值16.8 0.816*16.8-5èD¯n§^5ãbbs.3c3t.com_ÐõTã

只不过是为了换算成 施工规范上要求的压碎值而已 所以水泥混凝土的要计算一下èD¯n§^5ãbbs.3c3t.com_ÐõTã
