- high performance polymeric dispersants are primarily polycarboxylate polymer superplasticizers. These polycarboxylate polymers can increase the fluidity of the cement, thereby reducing the amount of water used to make the concrete material have higher mechanical strength. Such polycarboxylate polymers are also commonly referred to as polycarboxylate water reducers.
- Patent document CN102439063B discloses a compound having at least one phosphonic acid end containing linear polyglycerol.
- the use of such a compound as a water reducing agent can effectively maintain the slump spread of concrete.
- such a water reducing agent is expensive to produce and can cause a delay in solidification, and the solidification delay is prolonged as the amount of the additive increases.
