Plastic bags that are commonly used for packaging causes serious environmental problems. The accumulation of plastic bags increases every year. They can last in the environment for 1000 years without getting disintegrated. Disposal of a large quantity of plastic bags may cause serious land, water, and air pollution. The reuse of plastic bags can be done as one of the constituent materials for concrete, as plastic fiber improves certain properties of concrete.
MATERIALS
1. Cement - Ordinary Portland cement of 43 grade confirming to IS 8112-1989 is used.
2. Fine Aggregate – Natural river sand is used as fine aggregate, having properties which are determined by performing tests as per IS 2386(Part I). The results are:
3. Coarse Aggregate – Crushed granite stones from local quarries are used as coarse aggregates. The maximum size of the coarse aggregate that can be used is 20 mm. The properties of aggregate are determined by conducting the test as per IS 2386(Part III). The results are:
4. Water – Portable Water free from impurities and salt is used for casting and curing the concrete blocks as per IS 456-2000.
5. Plastic – Pieces of Polyethylene bag which are commonly used for packaging and carrying goods are used in concrete.
COMPRESSIVE STRENGTH- The compressive strength of concrete goes on reducing with an increase in the percentage of plastic pieces but the rate of reducing compressive strength is very low.
TENSILE STRENGTH- The splitting tensile strength observation shows the improvement of the tensile strength of concrete up to 0.8% of plastic.

The use of plastic can be possible to improve the properties of concrete which can act as one of the plastic disposal methods.

CYCLONE RESISTANT BUILDING CONSTRUCTION Cyclones have been an inescapable situation in India, especially in the eastern states of Odisha, West Bengal, and Andhra Pradesh. This calls for the construction of cyclone-resistant buildings in cyclone-prone areas to avoid loss of life and property. Low-lying coast areas, river floodplains, and sea-shore areas are highly vulnerable to cyclones. Certain settlement pattern even causes "funnel effect" which results in greater damage. While it's a common belief that heavier buildings are safer, in reality, a well built and engineered house provides better safety. Minimum standards for the design, construction, and performance of buildings to withstand extreme climate-related natural hazard events depending upon their locations should be set. We know cyclones are beyond human control but measures can be taken to reduce the loss of lives like evacuating people to safe areas, quick recovery of important fa...

Central Vista Project: Transforming the Political Face of India, the Civil Way

Image
    Source: Wikipedia     Central Vista Redevelopment Project  refers to the ongoing  redevelopment  to revamp the Central Vista, India's central administrative area located near  Raisina  Hill, New Delhi . The area houses India's government and parliamentary offices and has  been  described as the "power corridor" of the country. The project seeks to improve infrastructure for the Government of India, including retrofitting and refurbishing some heritage buildings to make them functional and safe.        Source: The Hindu   The Central Vista Redevelopment Project was launched in 2019 .   The project includes converting North and South Blocks into public museums while creating an ensemble of new secretariat buildings to house all ministries, relocating the Vice President and the Prime Minister's offices  and residences near the North and South Blocks, and revamping the 3 km (1.9 mi) long  Rajpath  between  Rashtrapati...

Demolition of Building Structures

Image
Demolition of a building is the process of dismantling or destroying a structure after its life of serviceability by pre-planned and controlled methods. It is the science and engineering in safely and efficiently tearing down buildings and other artificial structures . The tallest planned demolition of a building was the 47-storey Singer Building in New York City , built-in 1908 and torn down in 1967–1968 to be replaced by One Liberty Plaza Building Demolition methods: There are two types of demolition methods used for buildings and structures, Non-explosive demolition and Explosive demolition. In the non-explosive method, demolition of a structure is done with some equipment, without the use of any explosive. In contrast, in the explosive method, demolition is done with the help of bombs and explosives. Building Demolition Process: Different steps are involved in the process of demolition of building structures. They are: 1. Surveying 2. Removal of hazardous materials 3...
