商混搅拌站混凝土配合比怎么调整?

来源:http://www.zkzdsljbc.com/ 时间:2021-10-22

当商混搅拌站新拌混凝土有泌水现象时,应及时进行查明原因,如果不是外加剂和胶凝材料的适应性的问题时,可以调整粗骨料的掺配比例,将级配调整到最佳级配,切不能套用固定掺配比例.
In case of bleeding of fresh concrete in commercial concrete mixing plant, the cause shall be found out in time. If it is not the adaptability of admixtures and cementitious materials, the mixing proportion of coarse aggregate can be adjusted to the best gradation, and the fixed mixing proportion must not be applied
现场坍落度超出配合比设计坍落度的限制时,要及时分析原因,对砂石料含水率重新进行测定,对配合比进行校正,如果含水量实测、计算没有错误时,可以将减水剂掺量增加或减少0.05~0.1%进行调整.
When the site slump exceeds the limit of the designed slump of the mix proportion, the reason shall be analyzed in time, the water content of sand and gravel shall be measured again, and the mix proportion shall be corrected. If there is no error in the measured and calculated water content, the dosage of water reducer can be increased or reduced by 0.05 ~ 0.1%
当商混搅拌站生产混凝土的砂率偏大或偏小时,应及时进行查明原因,将砂率进行适当调整,调整比例为±1%如果用上述方法并不能解决商混搅拌站生产出的混凝土的问题时,应当立即停止生产混凝土,并寻找专业的维修人员进行维修,及时采取有效措施,避免出现其他质量问题.

When the sand rate of concrete produced by commercial mixing plant is too large or too small, the reason shall be found out in time, and the sand rate shall be properly adjusted to ± 1%. If the above methods can not solve the problem of concrete produced by commercial mixing plant, the production of concrete shall be stopped immediately, professional maintenance personnel shall be found for maintenance, and effective measures shall be taken in time, Avoid other quality problems
凝土的模板拆除顺序一般是先非承重模板,然后承重模板;先侧板,后底板。遵循行支后拆,先拆非承重部位,后拆承重部位以及自上而下的原则,拆模时,严禁用大锤和撬棍硬砸硬撬。
The removal sequence of concrete formwork is generally non load-bearing formwork first, and then load-bearing formwork; First the side plate and then the bottom plate. Follow the principle of removing after supporting, removing non load-bearing parts first, and then removing load-bearing parts from top to bottom. During formwork removal, it is strictly prohibited to smash and pry with sledgehammer and crowbar.
拆模时,工作人员应站在安全处,以免发生事故,待该段模板全部拆除后,才可以将模板、配件、支架等运出码堆。拆下的混凝土模板、配件等,严禁抛扔,需要有人接应传递,按指定地点堆放,并做到及时清理、修理和涂刷好隔离剂,以备使用。自上料搅拌车
When removing the formwork, the staff shall stand in a safe place to avoid accidents. After all the formwork in this section are removed, the formwork, accessories and supports can be transported out of the stack. The removed concrete formwork and accessories shall not be thrown away. They shall be received and delivered by someone, stacked at the designated place, and cleaned, repaired and painted with isolation agent in time for use. Self loading mixer
