Researchers from the Swinburne University of Technology have created a new type of concrete that is made from waste materials. The new concrete can bend under load, making it suitable for construction in earthquake zones. The waste product used in the concrete is fly ash, a by-product of coal-fired power stations. In earthquake zones, the brittle nature of traditional concrete can lead to building collapses. Concrete is the most widely used building material around the world.Traditional concrete is prone to shatter when stretched or bent and has a huge carbon footprint due to the calcination of limestone to produce cement, the key ingredient in concrete.
UltraTech Cement is planning to expand cement capacity from 9 MTPA to 14 MTPA in Anantapur district and Kurnool district of Andhra Pradesh.
The project will also include expansion of clinker capacity from 6.5 MTPA to 10 MTPA and waste heat recovery power plant capacity from 20 MW to 36 MW. The project worth Rs 1,250 crore will generate employment for 150 persons.
Vacuum Dewatered Cement Concrete (VDCC) roads, slip roads and 15 Cement Concrete (CC) roads will dot Secunderabad soon. The Greater Hyderabad Municipal Corporation (GHMC) is also taking up construction of reinforced cement concrete drain in Moula Ali and restoration of 70-km of arterial roads in Secunderabad.
The average plant load factor (PLF) of thermal power generation units is on a decline in the country. At 57.61%, the PLF in January touched a five-year low. In 2019, the PLF witnessed double-digit slump in most months. The fall corresponds to a decline in electricity demand, which recorded just a 0.28% growth in the year, the lowest since 2014
The coal ministry has plans for a big push on the use of domestic coal through gasification process to produce chemicals like methanol and fertilisers like urea for industrial purposes by 2023-24, a senior official reported.
Coal gasification is the process of producing syngas, a mixture consisting carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), natural gas (CH4), and water vapour (H2O).
