Polycarboxylate Superplasticizer Powder for Mass Concrete: Controlling Heat of Hydration Without Sacrificing Structural Performance
Polycarboxylate Superplasticizer Powder for Mass Concrete: Controlling Heat of Hydration Without Sacrificing Structural Performance

Mass concrete is defined not by its strength requirement but by its thermal risk. Any concrete placement where the cross-section is large enough for heat of hydration to generate a temperature differential between the core and the surface above 20 to 25°C is at risk of thermal cracking — and thermal cracking in a dam foundation, a thick transfer slab, or a nuclear structure base mat is a structural problem that cannot be patched after the fact.
