>Execution standard: B "Concrete Expansion Agent"
Product Introduction
>The abbreviation of calcium aluminate expansion agent ( ) is based on a certain proportion It is an anti-crack and waterproof expansion agent made from high-quality high-aluminum clinker, anhydrous gypsum and other inorganic materials. Its advantages include low alkali content, alkali-free aggregate reaction expansion, stable expansion rate, high concrete strength, and basically no impact on dry shrinkage in the later period. It is a safe and durable concrete admixture. Compensating shrinkage concrete can prevent or greatly reduce concrete cracking, improve concrete density and impermeability, thereby achieving self-waterproofing of the concrete structure. It has good technical and economic benefits in terms of simplifying the construction process, shortening the construction period, and extending or eliminating expansion joints.
>Specially recommended: crack-resistant and waterproof concrete to compensate for shrinkage concrete and filled concrete.
