Solid PCE Superplasticizer GR-B Heat Stable
GR-B is mainly used in construction precasting of high speed railway, high way, concrete station, dock, harbor, hydropower station, airport and etc. as well as in casting concrete, steel concrete and prestressed concrete. It can especially be used in the projects, such as nuclear power station construction, which require long construction time in premixing and high slump retention in concrete.
GR-B Heat Stable is a modified product of GR-B. It is customized according to customer requirements and is more stable in heat than GR-B.
