Green roofs or Eco roofs have become the latest design trend in almost all buildings. A green roof, also known as a living roof, is a building’s roof that is covered in vegetation and a growing medium. This is because of its wide variety of benefits ranging from energy conservation to carbon sequestration.
Thermal bridging can have a major impact on a dwelling’s overall thermal efficiency, even in very well-insulated homes. According to recent studies, thermal bridging has been found to be responsible for up to 30% of a home’s heat loss.
Chain surveying is a form of surveying that only takes linear measurements in the field. This is appropriate for surveying small areas with clear details and a relatively flat area. It gets its name from the fact that the chain is the most widely used piece of equipment.
Lightweight aggregate is a coarse aggregate used to make lightweight concrete for structural as well as non-structural applications.
According to the recently released IQAir AirVisual 2020 World Air Quality Report, India is home to 15 of the world’s 20 most polluted cities. Would you believe it if I say that a public emergency was declared in a city after its air quality index plunged to ‘severe plus’ levels of about 530? This happened nowhere other than New Delhi. Read on to find more about the Delhi Air Quality Index and what were the causes of this extreme level of pollution.
Air Pollutants Examples, Air Pollutants meaning, Effects of Air Pollution, Hazardous Air Pollutants, Major Air Pollutants, Primary Air Pollutants, Secondary Air pollutants, Sources of Air Pollutants, what air pollution is, What are air pollutants?, What are air pollution causes?, What are criteria air pollutants?, What are greenhouse gases?, What are the air pollutants?, What are the five major air pollutants?, What are the main air pollutants?, What is air pollutants?
It’s the need of the hour to take measures for air pollution control and prevention since millions of Indians are constantly exposed to polluted air. For instance, they breathe up to 25 micrograms/cubic metre of the lethal, microscopic pollutant PM 2.5 on a 24-hour average. This is well above the World Health Organization’s (WHO) limit of 10 micrograms/cubic metre.
ALC Panel or Autoclaved Lightweight Aerated Concrete panel is composite material consists of cement, lime, and silica sand. These panels use two-way welded steel mesh as reinforcement. Reinforcements are treated with anti-rust liquid. ALC panels are manufactured at high temperatures and are steam cured.
The splitting tensile strength test is performed on hardened concrete to determine its tensile strength. Marginal variations in water to cement ratio, ingredient proportioning, increase in a slump, etc impacts the desired concrete strength. This in turn affects the strength and stability of structures. There are several tests to determine the strength of concrete.
Cement tests are significant because cement is the most important and highly recognized binding material used in construction. Cement is an integral part of all types of construction ranging from huge skyscrapers, bridges, tunnels, etc to small residential buildings.
