FACTORS AFFECTING CONCRETE CUBE & CYLINDER STRENGTH RATIO
The relation between compressive strength of concrete cube and cylinder is complex. The various factors including inherent variations in concrete quality and comparison between cube and cylinder strength affects the strength ratio. Factors affecting Concrete Cube and Cylinder Strength Ratios ...
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. ...
How does Aggregate Properties Affect Concrete?
Coarse aggregates have properties such as size, shape, moisture contents, specific gravity, density etc. which affects concrete strength and durability in many ways. These effect of aggregate properties on concrete are discussed in detail. Concrete is a mixture of cementitious ...
Selection of Durable Construction Materials for Concrete Structures
Durable concrete construction requires selection of durable construction materials. Selection and properties of these construction materials are discussed.
Behaviour of Concrete in Extreme Fire
The behavior of concrete in extreme fire is dependent on the composition and properties of the concrete structure. The type of aggregates used, the mix design, the moisture condition, and age are the factors that govern the behavior of concrete ...
Effect of Air Entrainment on Concrete Strength
Air entrainment affects compressive strength of concrete and its workability. It increases the workability of concrete without much increase in water-cement ratio. Compressive strength of concrete is inversely proportional to workability of concrete. When workability of concrete increases, its compressive ...
Factors Affecting Strength of Concrete
Factors Affecting Strength of Concrete Concrete strength is affected by many factors, such as quality of raw materials, water/cement ratio, coarse/fine aggregate ratio, age of concrete, compaction of concrete, temperature, relative humidity and curing of concrete. Quality of Raw Materials ...
