Deficiency in construction
Poor workmanship is one of the most important causes of problems in buildings. Inadequate control in batching, mixing, transporting, placing, compacting, finishing and curing of concrete leads to various problems including spalling, segregation, poor strength etc. Often insufficient cover is provided for reinforcement. Poor quality formwork and poor preparation of joints also cause discomfort.
-
Deficiency of material
Use of poor quality materials, physical and chemical properties of concrete, increased water–cement ratio, etc. are also some of the major reasons.
-
Deficiency in design
Poor design is a major cause of structural failure. This may include load underestimation, poor mix design, poor specification, poor analysis, poor foundation etc.

Concrete Deterioration
Concrete is the most important construction material and today the worldwide consumption of concrete is 8.8 billion tons per year. Concrete, although a very durable material, can exhibit strength loss and deterioration over time for a variety of reasons.

Introduction to Building Maintenance
A safe and trouble-free structure is the dream of every engineer and resident. As far as medium and small buildings are concerned, leaks and cracks are the main cause of concern. An engineer or supervisor should be able to identify the type of inconvenience or damage and the cause of the malfunction, so that he…

What are Escalators
These are powered stairs. They are used when it is necessary to move a large number of people from floor to floor. These stairs run continuously without the need for operators. These escalators are in the form of inclined bridges spanning between floors. The components of an escalator are a steel trussed framework, hand rails…

Buildings Fire protection
All structural components of the building shall be constructed in such a manner and of such materials that they will resist fire in the event of fire (i.e., 1) for the duration required by the type of construction as an integral member of the building. do -1 for 4 types of buildings 4 hours to…

Causes and prevention of fires
A fire cannot occur under any of the following conditions: Absence of an essential component for combustion.Inadequate ratio of combustible material to oxygen to form a combustion system.The available heat source is insufficient to ignite the combustion system.The heat source is not available long enough to ignite the combustion system.It is possible to determine different…

What is Asbestos cement
This material, which is made by mixing fibrous minerals with portland cement, has great fire resistance value. Asbestos cement products are mostly used for construction of fireproof partitions, ceilings etc. Because of the poor conductors of heat and non-combustible materials, structural members fused with asbestos cement offer great resistance to cracking, swelling or disintegration in…

What is Glass
Due to its low thermal conductivity, this material undergoes very little change in volume during expansion or contraction and is therefore considered a good fire resistant material. However, sudden and extreme changes in temperature can result in fractures or cracks. When glass is reinforced with a mesh of steel wires, such as in wire glass,…
