土石方虚方实方换算1、石的实方和虚方的转换系数只有片石的表观密度与堆积密度的系数。（表观密度：材料在自然状态下，单位体积所具有的质量。堆积密度：散粒材料在自然堆积状态下单位体积的重量称为堆积密度。）我们取定片石的表观密度为2700kg/m3，堆积密度为1500kg/m3，则空隙率为44.44%，转换系数为1.8.仅供参考。2、土方转换关系土方分为天然密实体积、夯实后体积、松填体积、虚方体积等各种状态。其相互间的关系见下表所示：砌筑砂浆配合比表单位：立方米定额编号12345混合砂浆项目M1.0M2.5M5.0M7.5M10材料单位数量数量数量数量数量32.5Mpa水泥吨0.1580.1760.2040.2320.261石灰吨0.0750.0670.0550.0420.030中砂立方米1.0151.0151.0151.0151.015水立方米0.4000.4000.4000.4000.400定额编号67891011水泥砂浆项目混合砂浆M15M5.0M7.5M10M15M20材料单位数量数量数量数量数量数量32.5Mpa水泥吨0.3170.2160.2460.2710.3300.390石灰吨0.005----------中砂立方米1.0151.0151.0151.0151.0151.015水立方米0.4000.2900.2900.2900.2900.290抹灰砂浆配合比表单位：立方米定额编号123456石灰砂浆水泥砂浆项目1:2.51:31:11:21:2.51:3材料单位数量数量数量数量数量数量32.5Mpa水泥吨----0.7580.550.4850.404石灰吨0.2400.216--------中砂立方米1.2001.2000.7601.1001.2001.200水立方米0.6000.6000.3000.300.3000.300定额编号789101112混合砂浆项目1:1:11:0.5:11:0.2:21:1:21:0.3:31:0.5:3材料单位数量数量数量数量数量数量32.5Mpa水泥吨0.4670.5770.5040.3790.3910.368石灰吨0.2340.1440.0480.1920.0600.090中砂立方米0.4600.5801.0000.7601.1701.100水立方米0.6000.6000.6000.600.6000.600定额编号192021222324水泥白石子浆素水项目1:1.251:1.51:21:2.51:3泥浆材料单位数量数量数量数量数量数量32.5Mpa水泥吨1.1750.9790.7340.5880.4901.502白石子吨1.1471.2721.4721.5601.560--水立方米0.3000.3000.3000.300.3000.300
