Errors During Concrete Construction at Site and How to Avoid Them
Construction errors during concreting at site may occur due to failure to follow specified procedures and good practice or outright carelessness. Most of these errors may not lead to failure or deterioration of concrete, but they may have adverse impact ...
HOW TO CONSTRUCT DURABLE CONCRETE STRUCTURES
Achieving Durability of Concrete Structures: The durable concrete structures are to be conceptualised, specified, designed, contracted, constructed and maintained. To achieve the design life of the structure at reasonable maintenance cost, the following aspects are required to be taken care ...
Why do We Test Concrete Compressive Strength after 28 Days?
Strength of concrete is generally tested after 28 days as concrete cube strength or concrete cylinder strength. The reason for testing concrete strength after 28 days is discussed. Why do we test concrete compressive strength after 28 days? Concrete gains ...
Compressive Strength Test on Concrete Core – Calculation and Results
Compressive Strength Test on Drilled Concrete Cores is required to determine the strength of hardened concrete in structure. Calculation and results of test on concrete core is discussed.
Types of cracks in Concrete Structures
Types of cracks in Concrete Structures Types of cracks in concrete structures are structural cracks and non-structural cracks. Structural Cracks in Concrete Structural cracks are those which result from incorrect design, faulty construction or overloading and these may endanger the ...
What is Crazing in Concrete? Causes and Prevention of Crazing
What is Crazing in Concrete? Crazing in concrete is the development of a network of fine random cracks or fissures on the surface of concrete caused by shrinkage of the surface layer. These cracks are rarely more than 3mm deep, ...
Types of Chemical Attacks on Concrete Structures
Introduction When a concrete structure is prone to chemical actions its durability gets affected. The chemicals may cause cracking of concrete, volume change and deterioration of structure. The life of structure reduces and it can lead to failure of structures. ...
