Because brick/blocks and RCC are different materials, they expand and contract differently. Because this differential expansion and contraction leads to separation cracks, the joint between the masonry and RCC member should be reinforced with chicken mesh (PVC) overlapping 50 mm on both the masonry and the RCC member before plastering.
How to prevent cracks in concrete walls:
Begin with a reliable subgrade. Ensure that the subgrade has been compacted
Change the concrete mix. Keep the water to cement ratio low
Establish joints.
Cure the concrete as directed
How to prevent cracks in plaster walls:
Protect the plaster from the sun and wind to prevent it from drying out too soon. Start the plastering process at a time when there won't be much direct sunlight or wind on the surface.
Prior to plastering, thoroughly wet the masonry wall. This will prevent the brick from collecting plaster's moisture.
If the weather is hot, windy, and dry, begin curing as soon as possible (less humid)
Use sand with a fineness modulus between 2.4 and 2.6 and avoid using sand with less than 15% of the mass passing a 0.150 mm filter. If sand lacks fine material, add lime to cement plaster.
Finally, to sum up, I would like to mention a few steps that will help you with how to prevent wall cracks;
As work on the project progresses, add joints for mobility. In unreinforced walls, the distance between these joints should never be greater than 15m.
Use slip planes to help relieve stress in the nearby materials by allowing construction pieces to slide in relation to one another.
I have recently constructed a 2 storied villa property. I’ve meticulously followed a few steps in the prevention of cracks in buildings. A structure's appearance is compromised by cracks, but they also raise concerns about the structure's general stability, durability, and safety. I can share the measures that I adopted for the same.
How to Avoid Cracks in Walls?
Good Construction Practices:
The key to avoiding cracks is to use high-quality building materials, hire competent workers, and follow the right construction methods. Regular structural inspections can also find risks early on and fix them.
Appropriate Design and Planning:
Good design and planning, which take into account the stresses and possible movements of the structure, aid in the prevention of cracks. It's crucial to have enough expansion joints and to position the load-bearing components correctly.
Regular Maintenance:
Timely repairs and planned maintenance assist in seeing and resolving little concerns before they become larger ones.
Appropriate Drainage:
Another important factor in minimising moisture-induced cracks is proper drainage. A well-thought-out drainage system will divert water away from the structure, lowering the possibility of moisture-related cracks and water damage.
Appropriate Ventilation:
Changing temperatures can lead to cracks, which can be avoided with proper ventilation. The risk of building materials expanding and contracting can be decreased by maintaining proper temperature and humidity control in a well-ventilated building.So I considered these points to assist me with how to avoid air cracks in walls.Get Your Wall Cracks Covered by Availing Expert Painting Service from NoBrokerRead More:Why Wall Cracks in New House?
