Modern concrete and its types

A mixture of pate and clusters or rocks is known as concrete. The paste gets composed by Portland cement and water, and it gets coated on the surface into small or coarse aggregates.

Modern concrete is a difficult design. It depends on the required power and the needed look of the project that which mixes should be used. It also depends on the laws of construction in a specific area, codes of the building also matter in the mixture. The weather in which it will be exposed also need consideration when designing the mixture and to make sure that it is powerful and can stand for long, constructors take standard molded and standard-cures cylinder samples.  

The other important factor to be considered is the cost of the material that is being used in the mixture, also the tradeoffs, the slumps and most importantly the placement and the final presentation of the mixture. After all the mixing the mixture will be added with cement, water, chemical mixture, coarse and fine aggregates. There is a specific method of mixing all these things and condition to use it. These designs can be created with software programs. This software guide which type of mixing needed for which design.  

From the ancient times these concretes are being used for construction of buildings. Volcanic ash and hydrated lime were used in the regular common roman mixture. This was the most powerful mixture than other for buildings. Others were made of only with sand and lime. There was also the hydraulic concrete made of volcanic ash and clay.

Today when a batch needs to be mixed, it can be mixed with the recipe given on the packet of the concrete. The materials that can be used are Portland, dry sand, cement, water and dry stone. These things got mixed in a improvised container.  These materials get mixed in term of weight not volume. The sand should be of mortar or brick sand and should be used after filtrations and washed. It is important to remove all the organic materials from the sand and the stone if possible; this is what ensures the power of the mixture.

There are many types of modern concrete, and all of them are being used in many different construction purposes. These types are high-strength concrete, stamped concrete, high-performance concrete, ultrahigh-performance, self-consolidating, limecrete, previous and cellular concrete.

The formed mixture can be used in different constructions such as blocks and panels of walls, road sub-bases and maintenance, leveling floors, roof installations, bridge abutments and repairs, void fillings, and ground stabilization.
