Polycarboxylate Superplasticizer; Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, [9] follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
In materials science, superplasticity is a state in which solid crystalline material is deformed well beyond its usual breaking point, usually over about 400% during tensile deformation. [1]
Water reducers are special chemical products added to a concrete mixture before it is poured. They are from the same family of products as retarders.The first class of water reducers was the lignosulfonates which has been used since the 1930s.
Unfortunately, a growing body of research has detected contaminants and microplastics pretty much everywhere, including our tap water. Now, new research has detected microplastics in yet another ...
Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that ...

PVC, used extensively in sewage pipes, is only useful because of plasticizers. [1]A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
