[font=宋体][size=6]最大干密度：2.39g/cm3¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
最佳含水率为:5.3%¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
水泥剂量:6%¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
砂石掺配比例:50:50¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
我第一步:计算标准件用量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
2.39*2650.719*1.053=6670.98(有人说这一步需要乘以一个压实度98%,到底要乘不)¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
第二步:计算干混合料的质量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
6670.98/1.053=6335.21(砂石混合料总质量)¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
6335.21/2=3167.60(砂和石各一半)¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
第三步:求水泥用量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
6335.21*0.06=380.113¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
求水需要质量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
6670.98-6335.21=335.77¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
不知道我这样对吗?希望有人帮我解答下[/size][/font]¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)

第一步:¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
需要乘以要求的压实度，如98就要乘以0.98¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
第二步:求水泥用量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
第三步:计算砂石混合料总质量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
6335.21不是砂石混合料总质量应扣除水泥用量¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)

应先配混合料,再算水泥用量和用水量,再计算装入料桶用量.2039*2650.719*1.053*98%¾Æ¡ÞtËØbbs.3c3t.comâþNZâoÞàÜ)
