一、随车携带一些备用的减水剂
1、 Carry some spare water reducer with you
减水剂是一种能在保持混凝土塌落度不变的情况下,减少拌合用水量,随车携带,能很好地调节混凝土性能的混凝土外加剂。但加减水剂时,一定要记
Superplasticizer is a kind of concrete admixture which can reduce the amount of water for mixing and carry along with the vehicle under the condition of keeping the slump of concrete unchanged, which can well adjust the performance of concrete. But when you add water reducing agent, you must remember
得有混凝土试验室的人在场,否则混凝土质量不合
Someone from the concrete laboratory must be present, otherwise the concrete quality will not be good
格,后果将十分严重。
Well, the consequences will be very serious.
二、检查搅拌罐中的水量
2、 Check the amount of water in the mixing tank
每一次搅拌车卸货后返回车内时,应检查储水罐内的水量,并保持储水罐内的水随时处于满罐状态,以备不时之需。
When the mixer truck returns to the truck after unloading, the water volume in the water storage tank shall be checked and the water in the water storage tank shall be kept in the full state at any time for emergency.
三、离站前对混凝土质量的检查
3、 Inspection of concrete quality before leaving the station
由于原材料的不同,每车混凝土的质量也会有所变化。装运混凝土离场时,必须注意检查罐内混凝土的塌落度及易度,注意混凝土的凝固及混凝土的离
Due to different raw materials, the quality of each truck concrete will also change. When the concrete is transported out of the site, attention must be paid to the slump and workability of the concrete in the tank, the solidification of the concrete and the separation of the concrete
析沉淀。
Precipitation.
四、尽量减少搅拌车在路上运输的时间
4、 Try to reduce the transportation time of mixer truck on the road
水泥运输距离一般在20内,出车前要规划好行车路线及车辆的运行状况,限度地减少车辆上路所需时间。
The transportation distance of cement is generally within 20 km. Before driving, it is necessary to plan the driving route and the running condition of vehicles, so as to minimize the time required for vehicles on the road.
五、特殊情况为减少损失先卸料
5、 In special cases, the material should be unloaded to reduce the loss
如遇到特殊原因,造成长时间不能卸料的情况,应随时查看罐内混凝土情况,一旦发现混凝土搅拌车开始凝固。必须立即进行卸料,以防止整个冷凝罐报废。
In case of special reasons, if the material can not be unloaded for a long time, the concrete condition in the tank should be checked at any time. Once the concrete mixer truck starts to set. Unloading must be carried out immediately to prevent the whole condensate tank from being scrapped.
