Types of Admixtures of Concrete Cement | Chemical, Mineral

To achieve a higher strength by decreasing the water cement ratio at the same workability as an admixture free mix. To achieve the same workability by decreasing the cement content so as to reduce the heat of hydration in mass concrete. The commonly used admixtures are Lignosulphonates and hydrocarbolic acid salts.

How to Speed Up Concrete Drying | Hunker

How to Speed Up Concrete Drying. Once concrete is poured, it needs time to solidify and form solid chemical bonds before it can support weight or withstand force. Concrete is pliable as it dries, so it is preferable for it to dry quickly to avoid damage during the drying process. While you can speed up concrete drying only so much,...

Moisture Mitigation in Slabs Concrete Moisture

Concrete with a high watercement ratio produces more capillaries, making it easier for moisture to move through a slab quickly, but more water must leave, which also takes time. Slab drying time is dependent on the watercement ratio and the resulting capillary structure.

Concrete Wikipedia

WorkabilityEdit. When the cone is carefully lifted off, the enclosed material slumps a certain amount, owing to gravity. A relatively dry sample slumps very little, having a slump value of one or two inches (25 or 50 mm) out of one foot (305 mm). A relatively wet concrete sample may slump as .
