Concrete Definitions

1. Accelerator: A substance added to concrete to speed up the setting and hardening process.
2. Admixtures: Chemicals added to modify concrete properties.
3. Aggregate: Granular material like sand, gravel, crushed stone used in concrete.
4. Air Entrained: Concrete containing tiny air bubbles, improving its freeze-thaw resistance.
5. Air Entrainment: Inclusion of air bubbles in concrete for improved workability and freeze-thaw resistance.
6. Batching: Measuring concrete mix ingredients and introducing them into the mixer.
7. Bleeding: Water rising to the surface of concrete due to sedimentation of particles.
8. Bull Float: A tool for leveling and smoothing freshly poured concrete.
9. Compressive Strength: The material’s capacity to withstand load-reducing size.
10. Consolidation: Removing entrapped air from freshly placed concrete.
11. Cubic Yard: A measure of concrete volume (3x3x3 feet).
12. Curing: Maintaining moisture and temperature in concrete to develop strength.
13. Elastic Modulus: Measure of a material’s elasticity under stress.
14. Finishing: Treating the surface of freshly placed concrete for desired texture and appearance.
15. Formwork: Molds into which concrete is poured to form structures.
16. Grade: Concrete designation based on compressive strength.
17. Gravel Mix: Concrete mix primarily using gravel as aggregate.
18. Grout: A fluid form of concrete used to fill gaps and reinforce.
19. Hydration: The chemical reaction between cement and water in concrete.
20. Joints: Breaks in concrete to allow for expansion and contraction.
21. Limestone Mix: Concrete mix with limestone as a significant aggregate component.
22. Mix Design: Selecting and proportioning concrete ingredients for desired properties.
23. Performance Mix: Concrete mix designed for specific characteristics.
24. Portland Cement: The primary binding ingredient in concrete.
25. Ready Mixed Concrete: Concrete batched and mixed at a plant before delivery.
26. Rebar (Reinforcing Bar): Steel bars or mesh used within concrete for tensile strength.
27. Sack: Unit of measure in the concrete industry, often a sack of cement.
28. Sack Mix: Concrete mix specified by the number of cement sacks.
29. Screeding: Leveling and smoothing the top layer of concrete.
30. Set Time: Time required for concrete to reach a certain hardness level.
31. Slump: Measure of concrete’s consistency and fluidity.
32. Sub Grade: The soil or prepared layer on which concrete is placed.
33. Troweling: Smoothing hardened concrete surface using a trowel.
34. Vibrated Concrete: Concrete subjected to vibration for compaction and air pocket elimination.
35. Volumetric Mixer: Truck carrying raw materials, mixing concrete on site.
36. Water Reducer: Admixture decreasing water content in concrete mix.
37. Water-Cement Ratio: Ratio of water to cement weight in a concrete mix.
38. Workability: The ease of mixing, placing, and finishing a concrete mix.
