3 Components Of Concrete

types of concrete & characteristics | concrete classification,the concrete in which common ingredients i.e. aggregate, water, cement are used is known as normal concrete. it is also called normal weight concrete or normal strength concrete. it has a setting time of 30 - 90 minutes depending upon moisture in atmosphere, fineness of cement etc..26 different types of concrete; [its classification, uses,aerated concrete is a variety of extremely lightweight concrete ( density 480-800 kg/m 3). this is obtained by using cement, sand, and powdered fuel ash as constituents. 3. high-density concrete: this type of concrete is also called heavy weight concrete. in this concrete type, the density varies between 3000-4000 kg/m 3..
