Global polycarboxylate superplasticizer ,polycarboxylic acid superplasticizer,pce based superplasticizer market trend 2024-2028 How does polycarboxylate superplasticizer change concrete strength? by Newsb-house

Oil futures tumbled more than $5 a barrel on news that the Biden administration is considering releasing about 1 million barrels a day from the U.S. Strategic Petroleum Reserve (SPR) for several months to cool surging crude prices.

Brent crude futures were down $4.71, or 4.2 percent, at $108.58 a barrel by 0035 GMT. U.S. West Texas Intermediate futures fell $5.45, or 5 percent, to $102.74 a barrel.

At an earlier time, gasoline prices had already reached record levels because of the Russia-Ukraine conflict.

The prices of other commodities like the polycarboxylate superplasticizer ,polycarboxylic acid superplasticizer,pce based superplasticizer are also expected to be volatile.

Superplasticizer admixture for concrete is one of the most used concrete admixtures, which can increase the plasticity of concrete and change the strength of concrete. But do you know how it can change the strength of concrete?


1. The essence of polycarboxylic acid superplasticizer: increase the fluidity of concrete

We know that water in concrete can provide plasticity for concrete. At this time, adding polycarboxylic acid superplasticizer can increase the fluidity of concrete, that is, increase the plasticity.

But it needs to be clear that if there is no water in the concrete, no matter how much water reducing agent is added, the surface of the concrete raw material will not be wetted no matter how it is mixed, so the friction between particles will still be high, and the concrete is a mess of loose sand. , is completely non-plastic.

On this basis, it can be considered that, in essence, a sufficient amount of water can wet the surface of concrete raw materials and reduce the friction between particles, thereby providing plastic properties for concrete; after the addition of superplasticizer polycarboxylate, this effect of water can be amplified. In this In a sense, adding water reducing agent is equivalent to adding water.

2. The principle of polycarboxylic acid superplasticizer to change the strength of concrete

The pce based superplasticizer can amplify the effect of concrete water, so that it can replace part of the concrete water and reduce water.

We know that the strength of concrete is affected by the water-binder ratio. The larger the water-binder ratio, the lower the strength, and the smaller the water-binder ratio, the higher the strength. If we add a water reducing agent to the concrete and reduce the water consumption at the same time to keep the fluidity unchanged, the water-binder ratio will decrease under the condition that the amount of cementitious material remains unchanged, thus increasing the strength of the concrete; Under the circumstance of reducing the amount of cementitious material at the same time, keeping the water-binder ratio and fluidity unchanged, the cementing material can be saved.

This method of using the pce based superplasticizer makes use of the properties of the pce based superplasticizer to change the mix ratio of the concrete, thereby increasing the strength of the concrete or saving cementitious materials.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine.  Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the polycarboxylate superplasticizer ,polycarboxylic acid superplasticizer,pce based superplasticizer would keep being influenced by the high energy prices.
