Waffle slabs are two-way spanning slabs whose beams(in two diresctions) are at very close centres whereas a ribbed slab is a one way spanning slab whose secondary beams are at very close centres, but not their primary beams.

What is the difference between one end continuous slab and both end continuous slab?
nothing
What are the different types of concrete slabs?
Different types of Slabs :1. Conventional solid slab:-- the slab which is braced with beams and columns is called conventional slab this kind of slab is small whereas the depth of the beam is large and load is transferred to beams and from beams to columns. These types of slabs are used in constructing Floors of multi stored building. It is of two types.a) One-way Slab.b) Two Way Slab.2. Flat Slab:-Flat slab is a reinforced concrete slab secured directly by concrete columns or caps .flat slab doesn’t have beams.3. Waffle slab:- Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides. This kind of slab is majorly used at entrance hotels, malls, restaurants
What is the difference between one way and two way slab?
if LY/LX>2 than we use one way slab if <2 than use two way slab.One way slab supported only two direction and two way slab supported in all four direction.
Advantages of waffle pod slab foundation of home?
There is only one advantage of waffle pod slab construction - reduced cost. The waffle pod slab is no more than a slab of concrete placed on the ground, with polystyrene blocks in a grid pattern within. This results in a system consisting of a slab with a grid of stiffening and edge beams, giving the (reverse) effect of a 'waffle' if viewed from underneath.If construction is to take place on reactive soil, consideration needs to be given to the future maintenance of the slab. There is some requirement to ensure consistency in the landscaping and general treatment of the areas surrounding the slab. Typically, having concrete on one side, for example a driveway, gardens on another side, perhaps gravel on a third side and a timber deck on the fourth side can result in different soil moisture conditions which in turn can lead to structural movement and failure. Of course it is difficult to regulate the area underneath the slab.Builders often advise that consistent landscaping or even a concrete apron around the house is required to ensure reliable performance of the slab, unfortunately this advice is sometimes given when it is too late. Typically, category 1, 2 and sometimes category 3 cracks appear, and when the builder is advised he engages an engineer (usually the engineer who designed the slap) to give an opinion. Invariably, it seems to be the fault of the owner.The problem is that houses commonly have concrete on one side (the driveway) and gardens or lawn on another side, so the question really is, is it acceptable that the slab and foundation material be so fragile? Usually, stable foundation material will be found at a reasonable depth - perhaps 600mm - 1200mm. Home builders should obtain a quote for the price difference between a waffle pod slab and a conventional slab & beam construction, keeping in mind the cost of rectification in a cracking building and the effect on resale value.Builders should advise their clients accordingly and give them the option. At the moment, clients are not given the option, the display homes they are shown are not cracked, the brochures do not warn of the likelihood of cracking, they are not told of the onerous maintenance requirements, and it is not until it is too late that the issue arises.
Difference between one way slab and two way slab in construction?
Ans: One way slab is the slab having ratio of longer span to shorter span equal to or more than 1.5 . If the ratio of longer span to shorter span is equal to or less than 1.5, then such slabs are called as two way slab. In one way slab main tensile reinforcement is placed parellel to shorter side which will be the main steel, where as in two way slab both direction required main steel.
What difference suspended concrete slab between unsuspended concrete slab?
Supended slab are slab not sit on the ground directlySuspended slab is a slab supported by beams.
Can a waffle slab span 20 meters?
Yes waffle can be provided for 20m x 20m span but it becomes uneconomical
What is the difference between one end continuous slab and both end continuous slab?
nothing
Flat slab and oneway slab difference?

What are the disadvantages of a waffle slab?
Slab penetrations are limited to the maximum area of a single cell. One must have a structural engineer determine the viability of creating a slab penetration any larger than the size of a single cell to determine if reinforcement is necessary.
What is the difference between one way slab and two way slab?
when l/b ratio more than or equal to 2 then slab is designed as one way and when l/b ratio is less than 2 then slab is designed as two way.
Difference between one way and two way slab in reinforcement?
A one way slab reinforcement supports 2 walls while a two way slab reinforcement supports 4 walls. The one way slab reinforcement only supports walls in one direction.
