Brick work and workout task

 Masonry is required for the construction of foundations, walls, columns, partitions, steps, arches, and other similar structural components of the building. Masonry has an important role. 

• Supporting loads  
• Subdividing the space 
• Providing thermal and acoustic insulation 
• Providing fire and weather protection 

Classification of masonry walls can be done as. 

• Load-bearing walls 
• Non-load bearing or partition walls

 In this blog, we will study the different aspects of masonry such as materials, tools requirements, types of rubble, brick and block masonry, and a comparison of the type of masonry. preparation of masonry work, work procedure for masonry, checklist for masonry and woodwork, fixing details of door frames and windows, precautions to be taken while doing masonry work, points to be observed in masonry, etc. We will also go through the checklist for block/brick masonry.

 The thickness of the internal and external plaster MASONRY AND DOOR WINDOW FRAME FIXING depends on the quality of the masonry work. The cost of plastering work increases with an increase in the thickness of plaster. This means, at the time of the auction of masonry. the need for Good workmanship should be stressed, Practical Difficulties and their solutions will also be discussed in this Blog 

MATERIAL REQUIRED FOR MASONRY WORK AND ITS SPECIFICATIONS 

• Cement
• Sand
• Bricks
• Cement concrete blocks
•  Lightweight blocks 
• Stone rubble 
• Door and window frames (wooden and M.S.) 
• Chicken mesh & wooden planks 
• Scaffolding material like bamboo, Kathy or rope, and M.S. scaffolding 
• Primer, red oxide, and coal tar 
• Sieving screen 
• Holdfasts 
• Column strips (Column patti)

 

(1) CEMENT 

Generally. (OPC) ordinary portland cement is used for masonry and plasterwork. The quality and strength of masonry and plasterwork mainly de- pends on the quality of cement. So, cement should be tested in the field and laboratory, before use. Laboratory tests are time-consuming Which means quality can be ensured through field tests only. Cement should be checked for field tests like cement brand, manufacturing date. fineness, hardness, loading test & also laboratory tests like sound- Hess, setting time, etc. 

 (2) SAND

 Sand should be tested for silt content. It should not exceed 7%. Sand should also be checked for bulkage, for the correct quantity of sand can be added, and also check it for gradation, i.e., for khasua (very fine and shingle (very coarse). 

 (3) BRICKS 

Bricks should be checked for size, shape, frog. finishing, colour, soundness, breaking, etc. It should have a minimum crushing strength of 35 kg/cm  

(4) CEMENT CONCRETE BLOCKS

 are commonly used in masonry work. Two common types of blocks are Solid blocks and Cavity (hollow) blocks.

 (5) LIGHTWEIGHT BLOCKS

 It is a lightweight, structural material of steam cured cellular (aerated) concrete. It is available in blocks and large prefabricated units for floors, walls, and roofs of all types of buildings. These blocks are available in the following width, with various sizes such as 200mm, 150mm, 125mm. and 100mm. Commonly available light-weight blocks in the market are of SIPOREX make.

 (6) STONE - RUBBLE

 Stones for masonry work should be tested for different field tests like colour, appearance, absorption, hardness etc. as well as for laboratory tests. 

 (7) DOOR AND WINDOW  FRAMES (M.S.)

• WOODEN

 All frames should be checked for field tests like size, straightness, edges, wood material, colour, diagonals etc.  

• DOOR AND WINDOW FRAME (MS)

1.  Checklist for quality

•  Check the overall sizes, diagonals, and sections.
•  For the M.S. window, the type of section used e. g. Ahmedabad/Bombay, etc. is important. In the case of the Ahmedabad type section, there is a marking at every meter. 
• It is advisable to ensure that welding joints are properly ground. 
• Provision of holdfast. 
• Hole sizes for Waldrop and tadi Patti fixing.
•  Ensure that all the vertical members are straight in line. Also, check their plumb.  

Brick manufacture is the best startup for the construction line. As brick manufacturing is low skill and less machinery is required.  Many individuals have started making the bricks on the outer side of the city, where the construction is going on and later also adopt all the cement products like pipe, covers and pots.

Bricks should have proper size and frog for grips, clay bricks should be well burnt and should not have silt. water absorption should not more then 20 %

Building construction is a vast subject involving more than 1000 activities in the execution of building work. The engineer in charge of the project should be well conversant with planning, estimating and execution of the work, He should be aware of material information, design aspects, and work procedure. etc. to achieve the desired finishing product. The data and the information required for various activities have already been discussed in the respective blog.

Any Work is related to Materials and labour. If sufficient material and labour are available at the site work will be much faster. The Excel sheet shows' the labour required for various works. With that reference, we can calculate the labour required.
