Abstract:
The mechanisms of concrete slump loss are analyzed, with ChongqingLichuan railway works as an example, so as to solve the problem of high slump loss of concrete in summer. It is concluded that the causes for the slump loss include improper ambient environment, improper raw materials and improper mixing ratios. Proposal is made to take proper protection measures in summer seasons, use new cements and waterreducing agents and adopt proper mixing ratios. This paper can be used as reference to solve similar problems in the future.
