The term ?deflection? is defined as transverse displacement of a point on any straight axis to curved axis. It is expressed in metres (m).

The products of hydration are colloidal and increase surface area of solid paste during hydration and water is main ingredient which reacts chemically. The rate of hydration is mainly influenced by temperature of cement.

Dolomite bricks are made especially from dolomite it contains nearly 30% lime and 22% of magnesium se bricks are inferior to magnesite bricks. They are generally used in lining of blast furnaces.

The method ?Isoheytal? can be used for calculating run-off over an area. The remaining methods are effectively adopted to calculate slope and deflection at a point in any type of beam.

Plasticity in property of Material by which material can undergo permanent deformation and fails to regain its original shape on removal of load. Examples are gold, lead, etc.

Calcium chloride is more widely used as an accelerator. By adding two percent (2%) of weight of cacl2 admixture to Portland cement Maximum strength is attained within 1-3 days.

Macaulay?s method was devised by Mr WH Macaulay.
Advantages:
i. Gives one continuous expression for bending moment
ii. Constants of integration can be found by using end conditions
iii. By using this method, slope and deflection at any section can be determined throughout length of beam.

The slope at free end = A/EI = wl³/6EI
Maximum deflection at free end is Ax/EI; [x= ¾ l] y= wl³/6EI × ¾ l = wl⁴/8EI.

Lintel is a horizontal structural member spanning any opening to support loads of structure coming over it.
i) To facilitate fixing of doors and windows frames wherever.
ii) They used to receive load from wall constructed over m.

The Steel is be used for reinforcing a concrete for following properties:
i. Steel is about 30 times stronger in compression and 300 times stronger intention compared to concrete.
ii. It develops good bond with concrete
iii. It is highly fire resistant.
