Types of concrete slab

Types of concrete slabs in construction:-

There are 16 different types of Slabs in Construction. Some of them are outdated and some of them are frequently used everywhere. In this article i ll give a detailed explanation about an each slab where to use particular slab. Below are the types of concrete slabs.

Hardy slab and where it use

HARDY SLAB :- These kind of slabs are generally seen in Dubai and China. This slab is constructed by hardy Bricks. Hardy bricks are hollow bricks and made up of concrete Hollow blocks are used to fill portions of the slab thickness it saves the amount of concrete and hence the own weight of the slab is reduced. This kind of slab has a more thickness when compared with the conventional one. The thickness of hardy slab is 0.27m. The method of installing Hardy slab is different from normal and it is clearly explained below: This is a one of the types of concrete slabs. The dimensions of Hardy brick is 40cm x 20cm x 20cm The process of execution is as follows: Step 1 : Formwork is arranged and then shutters are fixed on the formwork. Step 2 : Hardy blocks are placed on the shutter with one brick gap on the entire shutter. Step 3 : The gaps between the bricks are called as rib. Reinforcement is provided in a form of beam within the gap. Step 4 : After placing the

About slump cone test in concrete

Concrete Slump Test for Workability -Procedure and Results. Concrete slump test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Procedure for Concrete Slump Test: Clean the internal surface of the mould and apply oil. Place the mould on a smooth horizontal non- porous base plate. Fill the mould with the prepared concrete mix in 4 approximately equal layers. Tamp each layer with 25 strokes of the rounded end of the tamping rod in a uniform manner over the cross section of the mould. For the subsequent layers, the tamping should penetrate into the underlying layer. Remove the excess concrete and level the surface with a trowel. Clean away the mortar or water leaked out between the mould and the base plate. Raise the mould from the concrete immediately and slowly in vertical direction. Measure the slump as the difference between the height of the mould and that of height poin

About Dome,Pitch roof,Arches slab

Dome Slab:- These kind of slab is generally constructed in temples, Mosques, palaces etc. And Dome slab is built on conventional slab. Thickness of Dome slab is 0.15m. Domes are in semi circle and shuttering is done on conventional slab in dome shape and concrete is filled in shuttering forming dome shapes. This is a one of the types of concrete slabs. PITCH ROOF SLAB: Pitch roof is an inclined slab , generally constructed on resorts for a natural look. Compared to traditional roofing materials Tile-sheets used in pitch roof slab are extreamely lightweight. This weight saving reduces the timber or steel structural requirements resulting in significant cost savings.Tile-sheets are tailor made for each project offering labour cost savings and reduced site wastage. And the thickness of slab is depends on the tiles we using it may be 2″-8″. This is a one of the types of concrete slabs. Advantages : 1. It sheds off rain water better. 2. It gives you internal storage or ro
