Formwork
🔸 Formwork is a temporary ancillary construction used as a mould for the structure, in which concrete is placed and in which it hardens and matures.
🔸 The cost of formwork may be up to 20℅ to 25℅ of the cost of structure
🔸 The operation removing the formwork is commonly known as stripping
♦️ Stripping time for different components
👉 Walls, columns and vertical sides of beam : 24 to 48hr
👉 Slab soffits (Props left under) : 3 days
👉 Beam soffits (props left under) : 7 days
👉 Removal of props to slab :
1. Spanning upto 4.5m : 7days
2. Spanning over 4.5m : 14days
👉 Removal of props to beam and arches :
1. Spanning upto 6m : 14days

Types of Admixtures Used In Concrete ...cont... 5- Pozzolanic Admixtures Pozzolanic admixtures are used to prepare dense concrete mix which is best suitable for water retaining structures like dams, reservoirs etc. They also reduce the heat of hydration…
Types of Admixtures Used in Concrete ... conti...
7- Gas forming Admixtures
Aluminium powder, activated carbon, hydrogen peroxide are generally used gas-forming chemical admixtures. When gas-forming admixtures are added, it reacts with hydroxide obtained by the hydration of cement and forms minute bubbles of hydrogen gas in the concrete. The range of formation of bubbles in concrete depends upon many factors such as the amount of admixture, the chemical composition of cement, temperature, fineness etc. The formed bubbles help the concrete to counteract the settlement and bleeding problems. Gas forming admixtures are also used to prepare lightweight concrete. For settlement and bleeding resistance purpose, a small quantity of gas-forming admixtures which are generally 0.5 to 2% by weight of cement is used. But for making lightweight concrete larger quantity generally, 100 grams per bag of cement is recommended.
8- Air detraining Admixtures
Air-detraining Admixtures are used to remove the excess air from the concrete voids. Sometimes, the aggregates may release the gas into concrete and air-entrained is more than required then this type of admixtures are useful. Some of the most used air-detraining admixtures are tributyl phosphate, silicones, water-insoluble alcohols etc.
9- Alkali Aggregate Expansion Preventing Admixtures
Alkali aggregate expansion in concrete is happened by the reaction of alkali of cement with the silica present in the aggregates. It forms a gel-like substance and causes volumetric expansion of concrete which may lead to cracking and disintegration. Use of pozzolanic admixtures will prevent the alkali-aggregate reaction and in some cases, air-entraining admixtures are also useful. Generally used admixtures to reduce the risk of alkali-aggregate reaction are aluminium powder and lithium salts.
10- Anti-washout Admixtures
Anti-washout admixtures are used in concrete especially for an underwater concrete structure. It protects the concrete mix from being washed out underwater pressure. It improves the cohesiveness of concrete. This type of admixtures is prepared from natural or synthetic rubbers, cellulose-based thickeners etc.
11- Grouting Admixtures
Grouting admixtures are added to grout materials to improve the grout properties according to the requirement of the grout. Sometimes, there is a need for quick set grout and sometimes there is a need for slow set grout to spread into deep cracks or fissures. Hence, different admixtures are used as grout admixtures based on the situation. Accelerators like calcium chloride, triethanolamine etc. are used as grout admixtures when the grout is to be set rapidly. Similarly retarders like mucic acid, gypsum etc. are used to slow down the setting time of grout. Gas forming admixtures like aluminium powder is added to grout material to counteract the settle of foundations.

How tall buildings resist the wind
👉Setbacks
Besides the forementioned corner softening and tapering buildings to resist the wind, alternating a building’s profile as it rises and including setbacks can also reduce the strength of vortices as they move around buildings. Some of New York City's early skyscrapers achieved this in response to the setback ordinances of 1916 - which was a measure adopted primarily to stop massive buildings from preventing light and air from reaching the streets below, and established limits in building massing at certain heights, usually interpreted as a series of setbacks. The most notable example of setbacks today is the 828 metre Burj Khalifa in the United Arab Emirates (UAE). This remarkable structure uses a range of techniques to resist the wind and achieve its height - including an extreme taper, multiple setbacks and high degree of corner softening, in which their effect can be demonstrated in a simulation developed using software such as SimScale.

Highway 1 in Australia is a network of highways that run around the country joining all the state capitals in the mainland Australia. The Highway 1 covers a distance of 9,000 miles and is one of the longest highways in the world. Each day more than one million people travel on the part of the road. Highway 1 was constructed in 1955 after a compilation of the already existing local tracks and roads. It is the only route to connect all the Australian territories and states except of the Australian Capital Territory. Most of the country’s highways are tributaries of Highway 1.

Trans-Canada Highway - Canada
Trans-Canada highway is transcontinental systems of roads maintained by both the federal and provincial governments and stretches from the west coast of Pacific Ocean and passes through all the ten provinces of Canada to the east coast at the Atlantic Ocean. The highway covers a distance of 4,999 miles long. The highway was approved by the Trans-Canada highway act of 1949 and the construction begun in 1950. It was officially inaugurated in 1962 and its completion was in 1971. At its completion it was the world’s longest uninterrupted highway and it was distinct with the white on green maple leaf markings along its stretch. In 2012, a number of public vehicle charging stations were installed along the highway by the Sun Country Highway company to allow owners of electric vehicles to travel across the entire highway.
