Problems of Steel With High Carbon

Recent posts


The concrete structure will guarantee stability and durability throughout its lifetime only if it gains an appropriate safety margin to resist and fight against the expected service forces and the environmental factors. The concrete deterioration can be studied by undergoing step by step levels of inspection.


The corrosion of steel reinforcement is the depassivation of steel with the reduction in the alkalinity through carbonation.

Requirements of Fresh Concrete

Fresh Concrete or Plastic Concrete is a Freshly mixed material which can be molded to any shape. The performance requirements of hardened concrete are more or less well-defined shape with respect to the shape, finish, strength, durability, shrinkage and the Creep. To achieve these objectives economically, the fresh concrete should satisfy a number of requirements from the mixing stage till it is transported, placed in the formwork and compacted.

Concrete Sealers- Buying Tips for Concrete Sealers

What are Concrete Sealers??
The concrete sealers are a special mixture that is applied to the concrete surface in order to protect from surface damage, corrosion and staining problems. These undesirable effects would result in the  formation of pores that would result in: Increase in porosity of the concrete surfaceWater penetration-causing freezing and thawingCrack FormationDecrease in durability of the concrete surfaceSubsurface failure due to water penetration, causing settlement

Bogue Compounds- Hydration Reactions

Chemical Composition of Cement The basic chemical composition of cement is given in table 1. For convenience, they are given short forms as shown in the table. The significance of each compound is discussed in the following sections. These compounds are together called as bogue compounds.

Stainless Steel Reinforcement in Construction - Designation And Standars

Stainless steel the name given to a group of corrosion-resistant steel alloys which contain a minimum of 10.5% chromium.When we refer "stainless steel" it won't simply refer to a single material type. But this will belong to a group of corrosion resistant highly alloyed steel. This type is in contrast to the unalloyed steel which won't show any kind of corrosion and rust forming that is noticeable in a normal environmental condition. 

Principle of Statics in Structural Analysis | Conditions of Static Equilibrium |Sign Convention

"Statics is the study of structures that are under equilibrium conditions. Equilibrium of the structure means - all the forces acting on the structure must balance and the net torque must be equal to zero".

Difference Between Carbon Steel (Mild Steel) And Stainless Steel

Understanding the main difference between the carbon steel and stainless steel is very essential when it comes to making a decision on which steel for a specified construction project. Choice in the grade of steel will come only after the choice between the carbon and stainless steel. In order to facilitate this choice, we will discuss the key difference between carbon steel and stainless based on different properties.

Light Weight, Heavy Weight & Normal Weight Aggregates - Properties & Applications

Based on the bulk specific gravity of the aggregates, the classification is made as Light Weight AggregatesNormal Weight AggregatesHeavy Weight Aggregates These aggregates have a major role in the manufacture of concrete with varied properties. The field application of these aggregates will hence vary based on the properties of the aggregates showed in the concrete made.

Polymer Composites in Construction

Polymer Composites are produced using polymers with the help of cement, sand or aggregates.

Factors Affecting the Strength and Density of Light Weight Concrete

The strength and durability of the LWA concrete is influenced by the following parameters:
· Grade and Granularity of the Aggregates · Grade and the proportion of the cement · Mixing water and consistency · Method of mixing · Compaction · Curing

Physical And Mechanical Characteristics of Lightweight Concrete

The following are the properties of LWAC
Particle Size, Shape and Surface Texture Specific Weight, Density, and Bulk Density Water Absorption Capacity Unit Weight Compressive Strength

Segregation in Concrete - Measurement, Causes & Types

Segregation of concrete can be defined ass the separation of the constituents of the material of concrete. A good concrete is one in which all the ingredients of the concrete are properly distributed to make a homogeneous mixture.

Segregation in ConcreteTypes of Segregation in Concrete
There are mainly three types or ways in which segregation can be observed in concrete. They are:
Type 1: The coarse aggregate will separate out or settle down from rest of the matrixType 2: The cement or the paste matrix will separate away from the coarse aggregateType 3: Water separating out of rest of material that has lowest specific gravity.Causes of Segregation in Concrete
There are many reasons behind segregation. This mainly depends on the handling, placing and the compacting operations. The chances to segregate are high with the increase in: Maximum size of the aggregateThe amount of coarse aggregateIncreased Value of Slump When there is a higher vibration carried out, the coarse aggregate will set…
