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 moreWhat is Lightweight Concrete ? Types & Uses
What is Meant by Stone Dressing ? The stone dressing is a process of surfacing and shaping of rocks available naturally. The place where the rocks are abundantly available is called as a quarry. The process of taking stones from the natural bed is known as ‘Quarrying’. The operation of stone dressing is generally carried … Read moreWhat is Stone Dressing ? Stages and Types
What is the Concept of Prestressed Concrete ? In case of big concrete construction projects like bridges, steel reinforcement bars alone won’t be sufficient to provide the necessary tensile strength. Pre-stressed concrete is used in all kinds of structures from bridges to buildings, silos and tanks. It’s a great way to minimize cracking and take fuller … Read moreWhat is Prestressed Concrete ?
What is Grades of Concrete ? As an Civil Engineer you could have come across the mentions of grades of concrete such as : M25 concrete for the RCC work in a foundation. M20 concrete for the roof slab. M15 concrete for PCC works etc. Have you ever wondered what do these grades of concrete … Read moreDifferent Types of Grades of Concrete

WBM Road (Water Bound Macadam Road). WBM road means water bound macadam road. The wearing surface of WBM road consist of clean and crushed aggregates which are mechanically interlocked by rolling operation. The material is bound with filler material (which are also called as screenings) and water, laid on prepared base course. Materials Required For … Read moreWBM Road : Construction Procedure, Advantages and Disadvantages
