Concrete expansion joint A concrete expansion joint or isolation joint is a gap that allows the concrete to expand and contract when the temperature changes. Expansion joints form a break between the other parts of a structure and concrete to allow movement without causing stress in concrete, leading to cracking. Expansion joints should be used in large concrete slabs such as concrete driveways and foundations. Need concrete expansion joints. All concrete will shrink slightly as the concrete dries and when concrete is set and then will contract and expand depending on the ambient temperature ..read more

Hydraulic cement A type of cement that hardens and sets very quickly with more water to the finely ground cement is called hydraulic cement. It is the most commonly used cement today. Nowadays, different usual compounds of modern Portland cement are commercially referred to as hydraulic cement on the market. Containing hydraulic calcium silicates (generally composed of calcium sulfate), It is a non-rusting, non-shrink and non-corrosive, substance widely used in construction projects. It is especially good for structures that are constantly resistant to water because it is impervious ..read more

Rainwater harvesting system We know that all living things like animals, humans, and plants needing water to live and carried out the different types of cellular activities. Rainwater Harvesting System So we can’t imagine a day without water. It’s very hard to imagine because we all use water for different kinds of daily activities, like cooking, cleaning, washing, drinking, and other more industrial and domestic uses. Today we all are heading towards the scarcity of water, and it’s mainly because of the lack of water conservation and also the pollution of water bodies. So let and don’t waste ..read more

Sheet Piling The sheet piling walls are used for large and small Waterfront structures, ranging from the small pleasure of boat facilities to massive dock structures where sea-going boats can take on or unload cargo. The pier of jutting into the harbor, consisting of two rows of sheet pining, makes a space between that it’s filled with paved and earth is same construction. The pilling of sheets is also used for erosion beach protection; for stabilized the ground slop and particularly for roads; and shoring walls of trenches and excavations; and for cofferdam. Sheet Piling When the height of th ..read more

Different scaffolding parts and types are used while constructing the temporary works for holding concrete work etc. The term scaffolding is generally used for the temporary structure used to support the concrete structure scaffolding or, more popularly, for supporting the worker during the construction (plastering, and brickwork or painting or repainting or renewal of structures, etc.). Scaffolding comes under safety regulations on construction sites. Therefore, use and standards have been prescribed for its layout.  For example, when a man is liable to fall from more than 3 me ..read more

what is rainfall Different types of rainfall occurs water moves from the streams or rivers up to there, forming clouds and the sky. Also, water goes from sea to sky. All these are part of the hydrologic cycle or water cycle. This cycle makes water move from sky to river and sea to sky. Without it, we cannot have lakes, streams, and even the sea. Therefore without this cycle, it will not be possible for animals or humans to live at all. Following are some stages of the water cycle: The cycle starts at sea, where water is warmed by the sun. Rainfall causes the evaporation of seawater. Thus seaw ..read more

types of precipitation Waterfalls from the sky in different forms. precipitation all form from the clouds which are raised about 4 to 11 miles (8 to 16 kilometers) above the ground in the earth’s troposphere. they take place whenever all forms of water particles fall from these reach the earth’s surface and high levels of the atmosphere. The drop to the ground is caused by gravity and frictional drag. When one falling particle drops water from the cloud, continuing drops and causing faster, it leaves behind a turbulent wake. Different Types of Precipitation Rain Raindrops liquid from the clou ..read more

Sheep’s foot roller It is one of the most commonly used soil compactors used by builders and contractors all over the world. The sheepsfoot roller is self-propelled heavy machinery which is typically mowed and runs static. This type of roller is available in a different variety of sizes depending on the nature of the soils. sheepsfoot roller design. It has almost hoof-like structures protruding from a roller to provide pinpoint pressure all across the soil.  which provides a kneading action for Protruding studs on the drum is similar to a sheepsfoot. The teeth size slightly different fro ..read more
