Scientists Have Reinforced Concrete With Plastic Waste

Researchers from James Cook University in Australia have created a type of concrete that's reinforced by plastic waste, rather than steel. The technique, which is a first in Australia, will greatly reduce the environmental impact of concrete, and we can't help but wonder why we're not doing this already.

Plastic Concrete: Building Bricks Made From Landfill Waste

sir,i want to know the mix design of Plastic Concrete: Building Bricks Made From Landfill Waste. Anonymous June 10, 2010 at 10:18 am I WANT TO A PROJECT IN PLASTIC BASE .


Most of waste materials produced by demolished structures disposed off by dumping them as land fill. Dumping of wastes on land is causing shortage of dumping place in urban areas. Therefore, it is necessary to start recycling and re-use of demolition concrete waste to save environment, cost and energy.


For working with concrete in hot weather, our CryoCrete™ Concrete Cooling Systems use liquid nitrogen as an alternative to traditional cooling methods. Manufacturing & Metal Fabrication Nitrogen is used as an effective way to prevent oxidation and provides a safe, inert atmosphere that “sweeps” off gases produced by furnaces.

Solvent Recovery and Waste Gas Purification

The liquid nitrogen evaporates and then enters as a cold gas in the first tube bundle of the cryo condensator. Here it transfers its cold to the exhaust gas flowing from below and warms up. The now warm nitrogen is now fed back to the evaporator and serves as a heat source for the evaporation of nitrogen.
