How does Concrete Superplasticizer Change the Strength of Concrete?

In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco, the propane contract price (CP) in March was $895 / ton, up $120 / ton from the previous month, up 15.48% from the previous month and up 43.20% from the same period last year. Butane contract price (CP) in March was 920 US dollars/ton, up 145 US dollars/ton compared with last month, up 18.71% month-on-month, up 54.62% compared with the same period last year; In March, CP in Saudi Arabia rose sharply, giving a strong boost to the international and domestic LPG market. Benchmark LPG prices are higher than a year ago as the economy continues to recover and demand for crude oil continues to repair. According to this trend, the market price of concrete superplasticizer will also be affected to a certain extent.

Concrete superplasticizer is one of the concrete admixtures which is used most frequently. It can increase the plasticity of concrete and change the strength of concrete. 

 

The essence of superplasticizer: increase the fluidity of concrete

We know, concrete water can provide plasticity for concrete, at this time to add superplasticizer, can make concrete fluidity increase, namely plasticity increase. 

But it needs to be clear that if there is no water in the concrete, even if you add more superplasticizer, no matter how to mix, the surface of concrete raw materials cannot be wet, so the friction between particles will still be very high, concrete is a pan of sand, completely do not have plasticity. 

On this basis, it can be considered that, in essence, a sufficient amount of water can wet the surface of concrete raw material, and reduce the friction between particles, thus providing plastic properties for concrete; After adding superplasticizer, you can amplify the effect of water, in this sense, adding superplasticizer is equivalent to adding water.

 

Principle of superplasticizer changing concrete strength 

Superplasticizer can amplify the action of concrete water, so as to replace part of concrete water, and play the role of water reduction.

As we know, the strength of concrete is affected by the water-binder ratio, the greater the water-binder ratio, the lower the strength, the smaller the water-binder ratio, the higher the strength. If we add superplasticizer in concrete, reduce water consumption at the same time, keep the fluidity unchanged, in the case of the same amount of cementitious material, the water-binder ratio will decrease, so improve the strength of concrete; If the water is reduced, the amount of cementitious material is reduced at the same time, and the water-binder ratio and fluidity remain unchanged, the cementitious material can be saved.

 

Concrete superplasticizer is used in this way to change the mix ratio of concrete then to improve concrete strength or save gelling material thereby.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the concrete superplasticizer would keep being influenced by the high energy prices.
