ABOUT THIS VIDEO :-
In this video Er.Chetan Sharma & Corporate Trainer of Civil Guruji (Civil Engineers Training Institute) is Explaining about How to remove cracks in slab by easy method.
Dr. Fixit Super Latex is based on modified Styrene butadiene latex used for high performance applications in
waterproofing and repairs. It is used for repairs of spalled concrete such as - floors, columns, beams, chhajjas, slabs &
waterproofing of toilets & bathrooms & terraces. It bonds strongly to old & new concrete & plaster.
Typical Applications
} As a bond coat - Plaster to plaster, concrete-to-concrete, plaster to concrete for plastering over brick masonry.
Bonding coat & mortar for tiles & panels, underlays for special finishes such as top rendering coat for chemical resistant
floors.
} As waterproofing - Waterproofing of small roof terraces, sunken portions of toilet & bathrooms, chajjas & lift pits,
balconies & staircase.
} As crack repair - Repairs of plaster cracks more than 5 mm & in gaps developed between masonry and RCC
members.
} As rebar coating - Coating for prevention of corrosion over rebars.
} For Cladding - Fixing or refixing of slip bricks, tiles, stones & marble bedding.
} Concrete repair mortars - Improves the durability of the mortars and it can be used for making polymer
modified mortars for patching and concrete repair.
} Cement mortars - For filling holes, reconstructing damaged areas and finishing surfaces on buildings and
precast elements in concrete .
Features
} Multipurpose - It is multipurpose & economical product, easy to use
} Cracking - It prevents cracking by improving flexural strength
} Hardness - Improves the hardness & prevents dust generation
} Shrinkage - Reduces drying & aging shrinkage cracks
} Bonding - Bonds strongly to concrete, masonry, stone work, plasters, steel & mostof the building materials.
} Erosion & corrosion - Improvers erosion resistance & prevents corrosion.
} Abrasion resistance - Improves abrasion resistance of cement mix.
} Waterproofing - Prevents leakage & dampness.
} Durability - Enhances strength of a repair mortar & provides durability.
} Rebound loss - Less material wastage- material does not fall back/ rebound, when used as bonding agent.
} Coverage - Excellent Coverage -70-80 sq.ft per kg/ in 2 coats, hence economical.
Method of Application
1 SURFACE PREPERATION
} Clean the surface with wire brush or scrubber to remove hidden dirt, loose particles, laitance, & dust. Degrease the
surface by using suitable solvents.
} Repair the concrete spalled portion by saw cutting the extreme edges of the repair location to a depth of at least 10
mm to avoid featheredging & to provides strong substrate.
} Clean the concrete surface to remove any contamination where breaking is not possible. Roughen the surface by light
scabbling or grit blasting.
} Expose corroded rebars in the repairing area fully. Remove all loose scales & corrosion deposits & immediately clean the surface.
Crack Types & Solutions
There are three main types of cracks in concrete. Each has its own cause and strategies to prevent or minimize.
Plastic shrinkage cracks. These occur during the first few hours when the concrete is still in a “plastic” state. They are caused when the surface moisture evaporates too quickly, usually during hot or windy weather. Synthetic fiber additives can help reduce this type of cracking, but do little once the concrete has cured.
Drying shrinkage cracks. These occur as moisture leaves the concrete after the slab has hardened. The main cause is concrete that is too wet, referred to as a “high-slump” mix. The best solution is to use less water in the concrete mix. Concrete suppliers sometimes add water to make the concrete easier to work with, but this weakens the concrete.
