Some areas believe that pump mortar can charge construction unit fees instead of using lubricating agents. This phenomenon is only temporary. As market competition intensifies, lubricating pipes are only a service, and lubricating pipe costs will become a loss for concrete companies. . In addition, no matter who pays, the waste generated by the lubrication mortar is inevitable, such as labor costs, material costs during the production of mortar, fuel costs during transportation, vehicle usage fees, etc. Once pipe moistening mortar is used in concrete structures, it will cause corresponding quality hazards and will bring certain quality risks to concrete companies. However, general construction units use pipe-lubricating mortar in places other than settlement, which inadvertently brings the risk of losing money to concrete companies. For example, concrete companies regard the use of lubricants as a service to customers, which can virtually increase their competitive advantages and become a bargaining chip for successful project bidding. </p
