问题:

背景:某工程用混凝土,经和易性调整、强度校核及表观密度测定,确定其单位用水量为190Kg,砂率宜用0.34,水灰比应用0.50,该混凝土的表观密度为2400kg/m3。

(一)计算该混凝土的试验室配合比。

(二)若该项混凝土用42.5强度等级的普通水泥(实测强度为48.0MPa)、碎石、中砂,估算其28天抗压强度。

(三)若掺用木钙减水剂,经试验减水率15%,计算每立方米混凝土的水泥用量。

(四)若施工现场砂含水率为3%,石子含水率为1%,计算施工配合比。

(五)若用I级粉煤灰取代部分水泥(取代率20%,超量取代率1.5),试调整其配合比(根据问题一所计算的试验室配合比)

附:

采用碎石时:αa=0.46,αb=0.07

几种材料的视密度:砂为2.68g/cm3水泥为3.0g/cm3粉煤灰为2.2g/cm3)。

施工现场配合比(以水泥用量为1计)为()。

A:1:1.76:3.22:0.40

B:1:1.74:3.21:0.42

C:1:1.72:3.32:0.40
