What are embedments in concrete? Embedments are any items for instance pipes, ducts, sleeves, and conduits placed in concrete elements for different purposes. Embedments are commonly manufactured f
Efflorescence in concrete is a whitish coloured powdered deposition of salts on the concrete surface that is formed due to evaporation of water from the concrete. It is caused when water soluble sa
Presence of impurities in water for concrete mix leads to decrease in structural properties of concrete such as strength and durability to a large extent.
Early-age cracking is a temporary shortcoming that crops up as a result of a faulty design and construction process. Such cracks can be repaired properly if necessary actions are taken on time. The
The sudden outpouring of rain on freshly placed concrete can give rise to unexpected challenges. The severity of the damage is dependent on the extent of surface protection and the curing procedure
There are various effects of fly ash on properties of hardened concrete such as strength, durability, creep, volume changes of concrete which are discussed.
Control joints are provided in a concrete slab to reduce cracks formed due to shrinkage. The specifications of the control joints such as the depth, timing and place of the cut play an important ro
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 prope
High-early-strength concrete can be developed using ordinary concrete constituents, special admixtures, and certain concreting practices. The high-early-strength concrete, which is also called fast
Accelerated Curing Method is used to get early high compressive strength in concrete. This method is also used to find out 28 days compressive strength of concrete in 28 hours. (As per IS 9013-1978
