Plain or Ordinary Concrete. ...
The use of short, discontinuous fibers to strengthen and toughen such materials, which are much weaker in tension than in compression, goes back to ancient times.
Light weight concrete
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
High strength concrete
High strength concrete is defined as concrete that has compressive of 55 MPa or greater. … Chemical resistant concrete, early drying concrete
Self compacting concrete
Self-compacting concrete (SCC) has many benefits in terms of production and placement compared to traditional concrete namely, elimination of external or internal vibration for compaction, better flowability, workability and pumpability, as well as increased bonding with congested reinforcement.
Ice concrete
The process of hydration of a concrete mix is heat liberating whereby any increase in the temperature of the concrete accelerates the rate of generation of heat. Concrete, in itself, is a bad conductor of heat therefore the evolution of heat due to the process of hydration occurs much faster than the rate at which it dissipates. These high temperatures developed have a number of effects some of which might even hamper the performance of the concrete in the long run. Ice concrete helps to alleviate this problem
Fibre concrete
Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Fiber reinforced concrete are of different types and properties with many advantages. Continuous meshes, woven fabrics, and long wires or rods are not considered to be discrete fibers. Fiber is a small piece of reinforcing material possessing certain characteristics properties. They can be circular or flat. The fiber is often described by a convenient parameter called “aspect ratio”. The aspect ratio of the fiber is the ratio of its length to its diameter.
Colour concrete
There are two main ways to colour concrete. The first uses a dry pigment that is brushed across concrete once it has been laid. The second uses liquid or dry pigment that is mixed into the concrete before it is poured.
Normal Strength Concrete
The compressive strength of normal concrete is between 20 and 40 MPa. The strength of high strength concrete is above 40 MPa. The high strength concrete has compressive strength between 40 and 140 MPa which is discussed in this article. As time goes the difference between normal and high strength concrete also changes.
