2. Types of concrete - Wikipedia

   en.wikipedia.org/wiki/Types_of_concrete

   Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material as the aggregate, and often mixed in improvised containers. The ingredients in any particular mix depends on the nature of the application.

3. Concrete - Wikipedia

   en.wikipedia.org/wiki/Concrete

   Pervious concrete is a mix of specially graded coarse aggregate, cement, water, and little-to-no fine aggregates. This concrete is also known as "no-fines" or porous concrete. Mixing the ingredients in a carefully controlled process creates a paste that coats and bonds the aggregate particles.

4. Ready-mix concrete - Wikipedia

   Ready-mix concrete (RMC) is concrete ... It is a mixture of Portland or other cements, water and aggregates: ... Each plant will have a batching recipe book (or ...

5. Portland cement - Wikipedia

   en.wikipedia.org/wiki/Portland_cement

   When water is mixed with portland cement, the product sets in a few hours and hardens over a period of weeks. These processes can vary widely, depending upon the mix used and the conditions of curing of the product, [18] but a typical concrete sets in about 6 hours and develops a compressive strength of 8 MPa in 24 hours. The strength rises to ...

6. Roman concrete - Wikipedia

   en.wikipedia.org/wiki/Roman_concrete

   Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar, a binder mixed with water that hardens over time. The composition of the aggregate varied, and included pieces of rock, ceramic tile, lime clasts, and brick rubble from the remains of previously demolished buildings.

7. Cement - Wikipedia

   en.wikipedia.org/wiki/Cement

   Cement powder in a bag, ready to be mixed with aggregates and water. [1] Cement block construction examples from the Multiplex Manufacturing Company of Toledo, Ohio, in 1905. A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together.

8. Roller-compacted concrete - Wikipedia

   en.wikipedia.org/wiki/Roller-compacted_concrete

   The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement. [2]

9. Self-consolidating concrete - Wikipedia

   en.wikipedia.org/wiki/Self-consolidating_concrete

   Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).
