4、水：饮用水。dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
5、外加剂为广州建宝新型建材有限公司生产的FDN-5B高效减水剂（粉末状颗粒），掺量为胶凝材料的1.4%。dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
四、配合比计算dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
初步配合比计算如下：dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
1、试配强度的计算：FC=50+1.645*6=59.9Mpa；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
2、水灰比的计算：本配合比采用假定法进行选定W/C，0=0.32；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
3、选定单位用水量：因设计坍落度为70-90则取W=191Kg/m3，但FDN-5B减水率为17%，W，0=191*（1-0.17）=159Kg/m3，，dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
4、计算单位水泥用量：C，0=W/（W/C）=497 Kg/m3；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
5、根据经验确定砂率：SP=31%；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
6、计算减水剂用量：497*0.014=6.958 Kg/m3；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
7、计算砂、石用量MS0、MG0 (采用质量法)dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
假定砼密度为2452Kg/m3得：MS0=555Kg/m3，MG0=1234Kg/m3；dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
8、经初步配合比按8升量进行试拌，该配合比的实测坍落度80mm、78mm，满足设计的70—90mm的设计要求，棍度和含砂情况为中等，保水性和粘聚性均良好。所以该初步配合比做为基准配合比。dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
基准配合比各原材料单位用量如下：dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
水泥：砂：碎石(4.75-26.5)：碎石(4.75-16)：水:FDN-5B=497：555：926：308:159:6.958=1：1.117：1.863：0.620:0.32:0.014在基准配合比的基础上，保持用水量不变，水灰比各增加或减少0.02，砂率也相应各增加或减少1%，则对应的W/C=0.30，SP=30%和W/C=0.34，SP=32%。dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
则相应的配合比各原材单位用量如下：dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk

根据以上配合比试验结果分析,A组、B组配合比满足试配强度要求，但本配合比为室内配合比，砂及碎石的含水量为零，在现场施工中应实测现场砂及碎石的含水量，并根据砂及碎石的现场含水量换算为施工配合比。恳请试验监理工程师结合施工单位的施工水平以及施工现场的实际情况,选取A组或B组配合比指导现场施工,请贵办审批。dœßØé0Y!ûbbs.3c3t.com}•ƒÅ.ì–ïk
