PLASTER INSPECTION Ensure all the checks ( Brickwork Checklist ) after block work is complied with. The aluminium template for openings (sometimes we use sand to cover the electric holes) should be available at the site. The blockwork should have been cured for 7 days and dry before plastering is started. Button mark the surface to be plastered keeping the minimum thickness. 12mm plaster is the desired thickness. The distance of button marks should be within an aluminium straight edge length. Plastering mesh should be 8” wide and fixed rigidly before plastering on the junction between concrete and masonry surface with steel nails / wooden plug and nails. This strip has to be plastered and cured for a minimum of 3 days before the entire wall is plastered. Get the plastering specifications like lime finish, trowel finish, sponge finish, rough plaster and zone of application clarified from architects. In the case of external plaster grooves, it can be incorpor...

FOLLOWING ARE THE PROCESS INVOLVE IN REPAIRING THE PLASTER 1. Setting up Scaffolding: Scaffolding if required for the proper execution of the repair work should be erected. A ladder can also be used in case of scaffolding if the work can be done safely. 2. Cutting of Old Plaster: The mortar of the patch, where the existing plaster has cracked, crumbled or sounds hollow when gently tapped on the surface, is first removed. The patch is to be cut out to a square or rectangular shape at position where repairing is needed. The edges of cut plaster is made under cut to provide a neat joint. 3. Preparation of Surface: The masonry joints which become exposed after removal of old plaster is raked out to a minimum depth of 10 mm in the case of brick work and 20 mm in the case of stone work. The raking is carried out uniformly with a raking tool, and loose mortar is dusted off. The surface is then thoroughly washed with water, and kept wet till plastering is commenced. ...

Following tests are conducted on bricks to determine its suitability for construction work. Absorption test Crushing strength test Hardness test Shape and size Color test Soundness test Structure of brick Presence of soluble salts (Efflorescence Test Absorption Test on Bricks Absorption test is conducted on brick to find out the amount of moisture content absorbed by brick,  In this test, sample dry bricks are taken and weighed. After weighing these bricks are placed in water with full immersing for a period of 24 hours. Then weigh the wet brick and note down its value. The difference between dry and wet brick weights will give the amount of water absorption. For a good quality brick the amount of water absorption should not exceed 20% of weight of dry brick. Crushing Strength or Compressive Strength Test on Bricks Crushing strength of bricks is determined by placing brick in compression testing machine. After placing the brick in compression t...

BRICK WORK Brick wall is made by joining bricks with cement mortar. We make brick wall to arrange floor area for different purposes of uses. It also provides privacy to dwellers. Properly made brick wall increase the beauty of building and rooms. Today we are going to publish a quality checklist during making brick wall.  Of course for making quality brick wall we have to choose quality bricks.  Soaking: Make sure bricks are soaked for at least 12 hours in clean water to remove salt and other chemicals from bricks. Cement Mortar: Make sure cement mortar is mixed properly in dry condition on a clean place. Check mixing ratio is properly maintained.  Check clean drinking water is mixed.  Make sure the mixed mortar is used within one hour after adding water. If you want, you can maintain register for tracking mixing time and ratio.  Wall: Check wall is located as per drawing at the time of making brick layout. Don't make wall above 5 feet in sam...
