According to the “Technical Specification for Construction of Highway Cement Concrete Pavement” JTG/T F30 and the “Code for Construction and Quality Acceptance of Urban Road Engineering” CJJ1, after the commercial concrete/on-site mixed concrete is transported to the paving site, except for the admixture dilution allowed by the laboratory, it is not allowed to add water arbitrarily; Only when the slump loss exceeds the standard and is confirmed by the supervisor and laboratory, can cement, water, and additives be added synchronously according to the mix proportion.
Simply adding water is a serious violation of regulations.
