Honeycombs in Concrete – Causes & Prevention

What is Honeycombs in Concrete ? When the surface looks very rough with voids and gaps between concrete and the reinforcement it is called as ‘Honeycombs in Concrete’. It looks very similar like the honeycomb. Honeycombs in concrete are serious problems which not only reduces the strength of concrete but also makes the reinforcement vulnerable. … Read more Honeycombs in Concrete – Causes & Prevention

Construction Joints in Concrete & It’s Advantages

What are Construction Joints in Concrete ? Construction Joints are placed when the mass concreting works are done and cannot be completed on a single stretch. The interface of the past days hard concrete and present days fresh concrete is to be properly done, So as the bonding should be perfect for load transferring and … Read more Construction Joints in Concrete & It’s Advantages

Segregation of Concrete & How to Prevent it

Concept of Segregation of Concrete Segregation of concrete means separation of ingredients from design fresh concrete resulting in the non-uniform mix. More specifically this implies the separation of coarse aggregates from the mortar because of differences in size, density, shape and other properties of ingredients in which they are composed. Because of segregation honeycomb is … Read more Segregation of Concrete & How to Prevent it

What is High Performance Concrete

Concept of High Performance Concrete (HPC) A concrete mixture which has high workability, high strength, high modulus of physical property, high density, high dimensional stability, low permeability and resistance to chemical attack is generally said to be high performance concrete. The American Concrete Committee on High Performance Concrete includes the following six criteria: Ease of … Read more What is High Performance Concrete

What is Lightweight Concrete ? Types & Uses

Introduction to Lightweight Concrete Lightweight concrete is a special type of concrete which weighs lighter than conventional or normal concrete. Density of light weight concrete is conventionally low. Generally 300 kg/m³ to 2200 kg/m³ and thus normal concrete has density between 2200 kg/m³ to 2600 kg/m³. Principle of Lightweight Concrete The basic principle behind the … Read more What is Lightweight Concrete ? Types & Uses
