Hocking in Construction, Hocking means doing small hits for concrete Constructed structure wall, floor, slab or roof, so that Piller or roof surface will become rough. Hocking in terms of building construction is process of making RCC Surface rough before applying plaster. If the surface is rough with little ups and downs, cement will get attached to the concrete surface with base level. Reer striking surfaces such as RCC Walls, columns, beams, slabs etc. in the concrete column, RCC member cutting available.
Hacking Concrete Pillar Construction
Bricklaying in which the bottom edge is set in form the plane surface of the wall. Striking a surface with a special tool so as to roughen it to take plaster. While doing hocking for concrete surface maestri has to hit a concrete roof/pillar for every 1.5/2 inches. same minimum dimension sizes for set RCC members. Perform this activity immediately after removing sheet centering/pillar boxes. Minimum recommended sizes for hocking buildings advisable to have 300 to 350 dents on an average per square meter. as well recommended to have mechanical bonding for plaster surfaces although you use chemical bonding materials.
Recommended and the best time to casting concrete. Hocking should be done at least after 3days from the date of construct concrete slab. Proper curing should be ensured before hacking is done to avoid any hairline cracks. concrete Hacking is used to making a smooth RCC wall, columns, slabs rough so that we can easily Apply plaster on it Hacking on construction surfaces is a manual process and is done by striking hacking hammers all over the old surfaces so as to create closely spaced notches for better interlocking.
Why Concrete Pillar, Slab Hacking Done ?
At this time concrete will be wet and soft. Otherwise, after a few days, concrete will become hard and workers need to put more effort to perform this activity. Before plastering a wall it is made rough so that plastering can be done efficiently. to better strick options Many people and construction labor don’t know about Hocking. In civil engineering, the word ‘hacking’ is used for this process of making the background rough before plastering for better bonding of mortar with R.C.C. Structure.
To understand local workers, In Local language hacking called Tacha. for plastering hacking is very important, it helps to hold mortar while plastering works. Hacking should be done at least after days from the date of removing the shuttering plate. RCC Works shall hack with tacha. tools also available for make simplified and removing shuttering plate data. Minus negative points covered like hacking is that it weakens the structure and hairline cracks develop which is vulnerable to water seepage. Hacking is about striking of surfaces such as RCC Walls, columns, beams and slabs. dent to the surface in order to create a proper mechanical bond with cement mortar, gpysum plaster directly applied on it.
Concrete finished surfaces is smooth, plastering materials would not bond with such surface. it will help in the mechanical bonding of plasters. Recommended having mechanical bonding by hacking always for plaster surfaces although use chemical bonding materials. Although bonding chemical helps in bonding between surfaces, mechanical movement keys will always enhance the plaster bonding with the substrate. Concrete Hacking in pillar, slab to gain more strength to attached materials. it should be done at least after 3days from date of casting the concrete. Proper curing should be ensured before hacking is done to avoid hairline cracks.
