Introduction:
When dry, powdery hydraulic cement is mixed with water, it dries and sets. It is thought to have been made by the Roman Empire and is still used today to build and fix things. The ingredients in hydraulic cement work together to shorten the time it takes to set, so it can harden even when wet. Hydraulic cement is better than regular concrete because it doesn’t shrink when it dries and may grow a lot. In this article, we’ll talk about hydraulic cement, how it can be used, and why it’s a big deal in the building business.
Hydraulic Cement – Types and Uses
Greater Male Connectivity Project
Introduction:
It is a project between India and the Maldives which is the result of bilateral consultation between the two countries. The contract has been signed by an Indian Company (Mumbai-based), AFCONS. This will be the largest-ever infrastructure project in Maldives which is known as the Greater Male Connectivity Project (GMCP).
Key points of the Project:
- A 6.4 km long bridge and causeway link will be constructed between Male and nearby three islands: Villingli, Gulhifalhu and, Thilafushi respectively.
- The project will use only renewable energy. It will use solar power for lighting purposes.
- The project will be funded by a grant of USD 100 million and USD 400 million as a Line of Credit (LOC) from India.
- It is the greatest infrastructure project of the Government of Maldives. It will provide a major boost to connectivity between the four islands accounting for about half of the Maldivian population.
- It will enhance the regular cargo ferry service between the two countries to boost trade and commerce.
Denmark’s Artificial Island
It is a project of Denmark in which an island will be built artificially in the North Sea. It will be located about 80 km into the North Sea and will cover an area of 2.6 square kilometers which is slightly less than the Central Park of New York city in the USA. The name of the island is Lynetteholm. The plans for the island have been made since 2018. It is said that the construction of the artificial island will not begin before 2035 and will be completed in 2070 which is almost 50 years from now. The project is being called the largest project to be undertaken in Denmark’s history. It is said that the island will be as big as 18 football pitches (120000 sq m), but there are hopes to make it three times that size.
Durability of Concrete
Introduction
Durability of concrete implies that a concrete can withstand any harsh environment without undergoing any change in structure. IS 456-2000 has specified norms that address the issues of the durability of concrete. Usually, a concrete can stand severe environment but when certain conditions like sea water exposure or sulphate and chloride attack is encountered with concrete then it becomes difficult for concrete to withstand such exposures. In such cases, along with concrete certain additives like accelerators or admixtures are required to add with concrete to make it durable. All these will be discussed in details here.
India’s First 3D Printed House
Introduction:
3D printing AKA additive manufacturing uses computer-aided designing to make prototypes or working models of objects by laying down successive layers of materials. In 3D construction printing (3DCP) process, the printing method is used to fabricate buildings or different construction components. The 3D printing technology is now a popular concept in recent years with many new companies. The technology uses different approaches using industrial robots, gantry systems and autonomous vehicles for fabrication of on-site and off-site fabrication of buildings. It includes fabrication of housing, construction components like cladding and structural panels and columns, bridges and civil infrastructures, follies and sculptures.
Silver Line Project
Introduction
It is a proposed flagship project of the government of Kerala for High-Speed Rail (silverline) project. It is a semi-high speed railway corridor which will connect Thiruvananthapuram to Kasaragod and thereby enhancing the state’s railway infrastructure and economic growth. The total length of the corridor is 530.6 km. The estimated cost of the project is Rs. 63,941 crores. The project’s new alignment will connect 11 districts and it aims to ease transportation along the entire north-south length of Kerala.

What is Skirting in Construction?
Introduction:
When completing the interior design of your home, there are numerous factors to consider. Searching for long-lasting, practical, and visually appealing materials would be best. Installing skirting or baseboards on your walls is a crucial decision you can make. The lowest portion of the wall, where it meets the floor, is covered with skirting boards. Skirting is an interior part of a home or structure that covers the seam where the floor meets the wall. It defines the bottom portion of a wall next to a floor as a baseboard or skirting board. Additionally, it is secured to the wall on both sides. These baseboards come in various forms that may be used for residential, commercial, or any.
What is Injection Grouting – Its Types, Procedure and Benefits
Introduction:
One of the most common issues that most construction workers face is dealing with holes, cracks, fine pores, uneven surfaces, etc. These not only deteriorate the surface texture but also weaken the overall construction. Germs, pests, and bugs can thrive in holes, cracks, and other depressions. So injection grouting is the best way to solve these issues. It is a new method of filling holes rather than reapplying plaster to the entire wall. Despite its importance, only some people are aware of injection grouting.
What is Drywall – Construction and Installation Process of Drywall, and Types
Introduction:
Walls and roofs have been the primary and most fundamental needs of human dwellings ever since the concept of a house was first conceived. Bricks replaced stones as the preferred material for construction. We used a lot of water to make mortar and let it cure, but that’s no longer necessary thanks to cement; thus, stone and brick masonry is becoming increasingly obsolete. A drywall is a type of wall that is not made of bricks or plaster; both need water in some way. As the world’s water supply dwindles, this is crucial in ensuring that future generations can continue to benefit from our current resources.
The Drywall System was developed by the U.S. Gypsum Company (USG) in 1916. The Sackett plaster firm, a division of USG, is responsible for the product’s original name, “Sackett Board.” Small fireproof tiles were offered for sale, but subsequent years saw the product reformulate into multilayer sheets of gypsum and paper. In fewer than ten years, it evolved into its present form, with compressed gypsum between two thick sheets of paper.
What is Refractory Concrete- Installation, Types and Uses
Introduction:
Improvements in building materials are constantly being made. The construction industry relies on wide concrete varieties for its many varied projects. Various constructions use refractory concrete to withstand high temperatures. Normal concrete melts at a particular temperature. High-alumina cement is often used to make refractory concrete, which can withstand high temperatures, along with aggregates that can also withstand heat.
