Preparation of surface for waterproofing work.

HOW TO PREPARE SURFACE FOR WATERPROOFING :-

 

  •  All surface area should be cleaned well to make visible of hair cracks / aggregate texture and opened the all the joints and construction joints.
  •  Cleaning of RCC member should be done by hacking tool, wire brush, wire grinder & air blower etc.
  • Make sure all kind of dust particles, oil & grease should be removed properly 


·         All visible cracks & construction joints should be sealed with cement mortar with additive Conplast  WL after making V groove.

           All clean & treated area should test for water tightness by flooding water for minimum 75 mm head for 48 hours. 


   All wet spots, water leak & honeycomb areas should be mark for treatment. It shall be treated with        injection grouting with Cebex 100 as additive to be added in grout cement slurry @ dosage of 225         gm.  of packet per bag of cement or micro concrete.

·       Areas to be grouted should be prepared to ensure substrates are clean, sound, and then pre-wetted. The unrestrained surface area of the grout must be kept to a minimum. Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process. Adopt usual placing or pumping procedures ensuring a continuous operation.

    Great article and this is helful!
    Water Proofing is something that all home and property owners must deal with at one time or another.

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.

Important points & characteristics of good concrete.

  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.

Brick, Classification of bricks and properties of good bricks.

  Brick:- Basically brick is a type of block which is used for the construction of wall and other building components. Classification of bricks - The brick can broadly be divided into two categories ·          1. Unburnt brick :         T he unburnt or sun dried bricks are dried  with the help of heat received from sun after the        process of moulding .These bricks can only be used in the construction of temporary and     cheap structure.  Such bricks should not be used at places exposed to heavy rains. ·            ·          2 . Burnt bricks- These are classified in four categories. ·         (i) First class Bricks:-   These bricks are table – moulded and of standard shape and they are burnt in kilns.   The surfaces and edges of the brick are Sharp Square smooth and straight.   First class bricks have all qualities of good bricks.   These bricks are used for superior work of permanent nature.    (ii)  Second class Bricks T hese bricks are ground moulded and t
