Influences of water reducing agent on concrete performance

First, water reducing agent can affect the fluidity of concrete. Under the same conditions, adding water reducing agent can change the fluidity of concrete by increasing the collapse degree. Secondly, water reducing agent can affect the condensation speed of concrete, adding water reducing agent can change its condensation speed, thus affecting the time used; Again, can affect its strength, adding water reducing agent can reduce the water-cement ratio, reduce the porosity of concrete inside, improve its strength; Fourth, the influence of its bleeding rate, in concrete mixed with air type water reducing agent, can reduce the water-cement ratio, improve its evacuation, so as to reduce the bleeding rate of concrete; Fifth, change its elastic modulus, adding water reducing agent can affect its elastic modulus by enhancing the hard movement of concrete; Sixth, can play a role in carbonization and prevent steel rust, by reducing the water-cement ratio, reduce the pore size of concrete, enhance its permeability, so as to reduce the occurrence of carbonization, better prevent steel rust.
