What is different types of concrete

 ● Types of concrete:- there is mainly two types of concrete according to binding material which are used:-

 (1) cement concrete

 (2) lime concrete

 ● (1) cement concrete:- it is mixture of cement, sand and aggregate and water, in this cement binding material for mortar  is cement. It is placed in any size of roof ,beam ,column and plinth and allowed to form hard surface like stone.

 properties of cement concrete

 1) it has high comprehensive strength

2) it is free from corrosion and  any change in weather or atmosphere does not affect on it

 3) it is proved to more economical than Steel

 4) it hardens with age in the processing of hardening continues for long time

 5) It bind with steel to form RCC

 6) there is initial shrinkage of concrete which is mainly due to loss of water and its bubbles

 What are grade of cement concrete

there is a several grade of mix concrete of different mix ratio are used to form building construction work ,culvert formation ,heavy wall formation and road and Footpath construction.

There is M5 ,M10, M15, M20 ,M25 ,M30 , M 35 M40 type of concrete mix.

 2) lime is also called quick lime ,it has very high caustic properties and it can dissolve human body .

 3) when lime is mixed with water its form calcium hydroxide Ca(OH)2 it is called as slaked lime. Used as binding material for brick wall

 4 ) after binding with brick walls next several week it react with carbon dioxide to form calcite .

 5) lime concrete provide good strength to bear sufficient load and also provide certain degree of flexibility.

 6) it can be available must cheaper rate

 7) it also act as waterproofing

 8) also resist weathering.

 What are main drawbacks of lime concrete 

 1) lime concrete is soft and gain longer time for gaining strength then cement concrete

 2 ) it takes long time to cure and setting ,today there is a sort of time

  3) lime cement does not hardening in water
