These are highly effective at reducing water articles and drastically Enhance the workability of concrete.
Setelah memahami konsep superplasticizer, penting juga untuk mengenal berbagai jenisnya agar dapat menggunakannya dengan tepat dalam campuran.
They're high-performance plasticizers that drastically make improvements to workability and move, letting for your reduction of water content even though sustaining a fluid combine.
Having said that, air entrained concrete will not be essential in all locations, significantly Those people with milder climates that will not practical experience harsh freeze-thaw circumstances.
