What are the Initial and Final Setting Time of Cement. Initial Setting Time of Cement. Initial setting time of cement is defined as the time elapsed between the moments when water is added to the cement to the time when the cement paste starts losing its plasticity. It can also be defined as the time … Read moreInitial and Final Setting Time of Cement
Hydration of Cement The Chemical reaction that takes place between cement and water is called as hydration of cement. This reacion is exothermic in nature, due to which considerable amount of heat is released during hydration of cement. This is called as ‘heat of hydration’. The hydration of cement is not a sudden process. This … Read moreWhat is Hydration of Cement ?
What is Fly Ash ? Fly ash is considered as one of the most important and advantageous waste material in construction industry. It is residue produced during the combustion of coal or any other form of coal. Nearly 30% of the coal is converted into ash on burning out of which 75% is in fine … Read moreFly Ash : Properties, Uses & Disadvantages
Concept of Stress Strain Curve For Mild Steel Generally mild steel rods are highly preferred for many construction purposes. As it has high tensile strength when used with concrete, knowing the behavior of mild steel rod under loading helps in choosing for better use. This behavior of a mild steel rod under loading can be … Read moreStress Strain Curve For Mild Steel
What is Workability of Concrete ? The term ‘Workability of Concrete’ is defined as the property of freshly mixed concrete which determines the ease and homogeneity with which it can be mixed placed, consolidated and finished. An ideal water-cement ratio alone is not going to give maximum strength. 100% compaction of concrete is an important … Read moreWorkability of Concrete & Factors Affecting It

What is Dampness ? Dampness is the presence of moisture in the various parts of buildings such as a floor, wall, roof etc. Dampness is either formed due to inclusion from outside or condensation within the building. Dampness in the building leads to unpleasant and unhygienic conditions to dwellers thus sufficient care must be taken … Read moreDampness & Damp Proofing Materials
What is Cement ? Cement is generally known as ‘Portland Cement’ in civil engineering works. It is generally used as a binding material, which sets well and hardens quickly under water and gives the desired strength. The purpose of each grades of cement is same, that is to bind the materials used in concrete. The … Read moreDifferent Grades of Cement
What is the meaning of Floor Space Index ( FSI ) ? FSI stands for ‘Floor Space Index’ also known as ‘Floor Area Ratio’. Floor Space Index means the ratio between the area of a covered floor to the area of that plot on which a building stands. This numeric value indicates the total amount … Read moreWhat is Floor Space Index & How to Calculate it
What is Meant By Concrete Spalling ? Concrete Spalling is breakaway of concrete surface which often extends to the top layers of reinforcing steel. Spalling maybe 150 mm or more in diameter and 25 mm or more in depth and the occurrence of smaller concrete spalls is also possible. Spalling of concrete also affects a … Read moreConcrete Spalling : Causes & Prevention
