Nano Concrete Introduction The addition of nano-sized particles to concrete can enhance its properties, such as strength, durability, and self-cleaning abilities. Nano concrete has a denser and stronger material due to the addition of nanoscale particles that fill in the spaces between larger concrete particles. Nano concrete is more resistant to water and chemical damage … Read more

As the name suggests concrete vibrator machine is a mechanical device for creating a vibration in wet concrete. It comes in various shapes and sizes. The concrete vibrator has a different needle-like 25 mm to 90 mm. The selection of vibrator needle is based on center to center spacing between two or more steel bars. If the … Read more
In reinforced concrete structures, understanding the differences between clear cover, nominal cover, and effective cover is crucial for ensuring the durability and strength of the construction. The concrete cover is provided in all structural members like footing, column, beam, slab, etc. It is provided for a long life of the concrete structure and to prevent … Read more
Prestressed concrete is a type of concrete that is strengthened by pre-tensioning or post-tensioning steel wires or bars inside it. This technique allows for the construction of stronger, more durable structures that can withstand greater loads and stresses than traditional reinforced concrete. The advantages of prestressed concrete include improved structural efficiency, reduced material usage, and … Read more

There can be different types of defects that can occur in concrete structures it may be crazing, cracking, blistering, dusting, delamination, efflorescence, scaling, spalling, and Curling. These defects can be due to various reasons or causes. Causes Of Defects … Read more
The Poisson’s ratio of concrete varies 0.1 to 0.2. Poisson’s ratio (ν) is a measure of the ratio of lateral strain to longitudinal strain when a material is subjected to an axial load. Poisson’s Ratio Of Concrete When a concrete specimen is subjected to axial loads the ratio of transverse strain to the longitudinal strain … Read more
Calcium chloride is a concrete admixture. It works as an accelerator. This blog article explains use of calcium chloride in concrete as an accelerator. Introduction Calcium chloride is used as an accelerator in the hydration process of cement. Calcium chlorides decrease the setting time of concrete and lead to the quick settlement of concrete to get high initial strength of … Read more
Introduction Pouring concrete on a sloped surface needs good skills and experience to perform the work as planned. Commonly, low slump concrete is used for sloped concrete members, driveways, and wheelchair ramps. Low slump concrete is used for the inclined members. Some examples of slope members are staircase, ramp, etc. The placement of low slump … Read more
