Abstract: Abstract: Efficient water reducer plays a key role in the allocation of high performance concrete. The experiment uses four grades concrete of C15, C20, C25 and C30 by setting the different water-cement ratio. Each grade is divided into adding water reducing agent and not adding.To test the concrete strength of eight groups by testing compressive strength gains the relationship between the concrete strength added water reducer and water-cement ratio. Through processing experimental data, to get the role water …
