Selection of Sustainable Supplementary Concrete Materials

Due to resource scarcity, environmental impact, and socioeconomic constraints, sustainable criteria should be given prime importance in the construction industry. The sustainability in concrete can be attained using supplementary materials. The numbers of supplementary concrete materials (SCMs) are available ranging from industries by-products, agro-products, waste product, and newly

Use of Recyclable Materials in Sustainable Civil Engineering

The paper by S. Talukdar et al. investigated the use of waste materials, such as crushed glass, ground tire rubber, and recycled aggregate, in concrete. Test results demonstrated that ground tire rubber introduced significant amounts of air into the mixtures tested, affecting adversely their compressive strength.

Shotcrete - Wikipedia

The wet-process procedure generally produces less rebound, waste (when material falls to the floor), and dust compared to the dry-mix process. The greatest advantage of the wet-mix process is all the ingredients are mixed with the water and additives required, and also larger volumes can be placed in less time than the dry process concrete .

MIT students fortify concrete by adding recycled plastic

Oct 25, 2017 · Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world’s human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry’s global carbon footprint.
