Admixture technical notes
Practical articles written for concrete producers and buyers: how to keep slump in hot weather, how anti-clay agents work, how to fix common concrete problems with the right admixture.
How to control slump loss in hot weather
High temperature accelerates cement hydration and steals workability before the mixer arrives. Practical options: retarder, water-retaining agent and dosing timing.
Anti-clay agent: how it works with high-mud aggregate
Clay fines adsorb PCE superplasticizer and make dosage unstable. Anti-clay agents block the clay surface selectively. How to diagnose and dose them.
Foam, bleeding, slump loss: fixing concrete problems with the right admixture
A practical map from symptom to admixture: excess air and foam, bleeding and segregation, slump loss, and slow or fast setting.
