Admixtures act like boosters for concrete, giving it special properties it otherwise wouldn’t have. They generally make up less than 5% of the total mix and can come in a powder, liquid, or fiber form.
Fly ash can help earn LEED certification.
For high-performance, high-strength applications, silica fume provides a number of benefits.
Add synthetic fibers to strengthen concrete for multiple applications.
Tiny steel fibers improve the mechanical properties of concrete.
Waterproof an entire concrete structure.
For more consistent setting times and workability than standard water reducers use a mid-range water reducer.
Recommended for conventional steel reinforcement as well as prestressed or post-tensioned concrete that will be exposed to chlorides from marine environments or deicing salts.
Gives concrete high early strengths without sacrificing workability.
Improves stability and segregation resistance without significantly reducing slump or flow.
Improves the adhesiveness and water repellency of bonding paste/mortar in pervious mixes.
Extends the plasticity of the concrete, increasing workability and reducing labor costs.
Where the use of calcium chloride is prohibited, speeds up the hydration (hardening) of the concrete, allowing the concrete to set faster and crews to finish earlier.
Ensures predictable and delayed set times.
Improves workability of concrete.
Creates microscopic voids for water to fill during freezing cycles, preventing cracks caused by the expansion of the beads of ice.
