What is concrete and the function of it's ingredients?

-
Concrete :- Concrete is a composite material defined as the mixture of cement, sand, coarse aggregate and water. Which is used for construction of building, infrastructure etc.



The function of ingredients of Concrete:-

1:- Cement:- Cement is the most important ingredient of concrete. It is used to bind the aggregates, fine sand and coarse sand.

2:- Water :- Water is used for the lubrication of the aggregates and to cause chemical action with the cement called hydration. Water used in concrete should be potable without any inpurities. Clean water should be used in concrete.

3:- Fine Aggregates:- The aggregates which can pass through the IS sieve No. 4.75 are called fine aggregates. It's used to make concrete dense by filling the the voids and gaps of coarse aggregate and also to reduce the shrinkage of the cement on hardening. The use of the fine aggregates to make the concrete mix economical.

4:- Coarse Aggregates:-  The aggregates which pass through the IS sieve 75 mm mesh and retained on the 4.75 mesh are called coarse aggregate. The function of the coarse is to make the concrete strong and weather resistant.

IMPORTANT MECHANICAL PROPERTIES OF MATERIALS

Important mechanical properties of materials:- ELASTICITY:-  In this property body regains completely its original shape & size then it is called perfectly elastic body. Elastic limit marks the partial break down of elasticity beyond which removal of load result in degree of permanent deformation. Steel, aluminium, copper, may be considered to be perfectly elastic within certain limit   ·      Plasticity:- The characteristics of material by which it undergoes inelastic strain beyond those at the elastic limit is known as plasticity.   This property is particularly useful in operation of pressing and forging. When large deformation occurs in a ductile material loaded in plastic region, the material is said to undergo plastic flow. Ductility:- It is the property of material in which a material can be drown out longitudinally to a reduced section, under the action of tensile force.   A ductile material must possess a high degree of plasticity and strength. Ductile

  The volume of one 50 kg bag of cement is 34.5 litres   About 19 litres (38%) of water is required to hydrate 50 kg cement in sealed container.   The ordinary Portland cement when tested for its compressive strength at 28 days   according to the method describe by the standard specification, yields a minimum compressive strength of 43N/mm2 is called 43 grade  cement . Too fine cement is susceptible to air set and deteriorates earlier.   The setting time of cement can be controlled by varying the quantity of gypsum in cement. Sometime with the addition of water to cement, a premature set occurs within 5 minutes. This is called false set an is due to  the presence of anhydrous gypsum which is formed due to grinding of gypsum with too hot clinker .this is not to be worried .continuous mixing aggregates , cement and water will break the false set without  harming any property of the concrete .  The ability of cement to maintain a constant volume is known as soundness of cement. The abilit
