Introduction:
Maintenance of roads is the continual work to ensure they are in good shape for drivers and pedestrians. It entails normal maintenance, like fixing small problems like potholes and cracks in the pavement, and major repairs, such as repaving or reconstructing larger stretches of road. Regular road maintenance is crucial to ensure the safety of drivers, passengers, and pedestrians, avoid vehicle damage, and lessen traffic congestion. Depending on where you live, municipal, state, or federal governments may be responsible for road maintenance.

Introduction:
Geocell is a cellular confinement system made from high-density polyethylene (HDPE) commonly used in road construction as a soil stabilization solution. Using geocell in road construction dates back to the 1970s when the U.S. Army Corps of Engineers developed the technology to stabilize the ground for military applications. The first documented use of geocell in road construction was in the late 1980s when the technology was used to stabilize the shoulders of an access road leading to a copper mine in Chile. This initial use was successful, and geocell began to gain popularity as a solution for soil stabilization in road construction projects worldwide.

Over the years, the technology has evolved, and the use of geocell has expanded to include applications in retaining walls, erosion control, and even green roofs. Today, geocell is a widely accepted and cost-effective solution for soil stabilization in road construction projects, particularly in areas with poor soil conditions or unstable terrain.

Introduction:
When making a roof, it’s important to know how the building is assembled and how each part supports the whole. Rafters are a key part of a roof’s frame. They must be cut and measured carefully so that weight is evenly distributed and the building stays safe. In architecture and construction, a rafter is a structural component that supports a roof and helps transfer the roof’s weight to the building’s walls.

Rafters are typically made from wood or metal and are placed at regular intervals along the length of the roof. The shape and size of rafters can vary depending on the roof’s design and the structure’s weight and load-bearing requirements. In traditional construction, carpenters often cut rafters on-site using hand tools, but today pre-cut and pre-engineered rafters are commonly used for efficiency and cost-effectiveness.

Introduction:
One of our ancestors wanted to separate two areas, so they thought of building a wall. All types of walls are made to protect, keep people out, or defend. Building a building on pillars and walls is a familiar idea. Even though the building elements have changed from the past to the present, the goal is still the same. There was a time when walls were built with dirt and trash using certain methods. Then came the stone wall, and the pieces are still being put together in new ways. Every day, different types of walls take on new forms because of changes and improvements.

What is a Wall?
A wall is a vertical structure, usually made of brick, concrete, or stone, that serves as a physical barrier or divider between spaces. Walls can be found in various settings, including residential, commercial, and industrial buildings, and outdoor environments, such as gardens and parks. In addition to providing a physical barrier, walls can offer security, privacy, and insulation from noise and weather. They can be decorative or functional and may serve various purposes, such as defining boundaries, supporting roof structures, or providing a surface for artwork or signage.

Introduction:
Thermal insulation materials are an important part of buildings. They are meant to stop heat from escaping and keep the temperature inside comfortable. Insulation materials are used in walls, floors, roofs, and ceilings to keep heat from escaping or getting in. It can save energy and cut down on carbon emissions. Several things, like the building’s design, the climate, and the money, affect the choice of insulation material. Some things that affect how well insulation works are the material’s R-value (thermal resistance), ability to keep air out, and ability to fight moisture.

Thermal insulation materials help save energy and have other benefits, such as reducing noise, preventing fires, and making buildings last longer. Because of this, thermal insulation has become an important part of building planning and construction in modern times.

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.

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.

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.

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.

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.
