May 22, 2024 · Scientists say they've found a way to recycle cement from demolished concrete buildings. Cement is the modern world's most common construction material, but it is also a huge source of...
The inability to test concrete (before it is cast) means structures are built with onerous strength reduction factors that allow for material variability. With ‘stock’ components, the performance can be assurance tested, so this is another opportunity to improve on normal practice.

Determining whether recycled aggregates are fit to use, and for which purposes, is a fundamental part of the production process. Classified as a waste recovery operation, recycled aggregate production must meet strict waste management controls. Producers are also required to maintain full compliance with WRAP’s quality protocol and testing criteria...
Recycled aggregates need to be tested to determine whether or not the material is fit for purpose. With many aggregates used for concrete and highways, strength, durability, and low maintenance are of paramount importance. Testing ensures recycled aggregates can be used with confidence, knowing that all necessary standards have been met – but visua...
Recycled aggregates undergo rigorous testing depending on the product’s future application. There are numerous tests used, including those for gradation, fines, plasticity, and contaminant content. Gradation A gradation test measures the size, coarseness, and distribution of particles in a sample using what’s known as a sieve analysis. The correct ...
At ETM Recycling, we take WRAP’s quality protocol extremely seriously, taking a number of additional measures to ensure our recycled aggregates consistently meet standards. We also continually look to improve our products in line with ISO 14001. Below, we take you through some of our rigorous processes. 1. Our strict protocols ensure all our aggreg...

Feb 1, 2022 · From a waste management perspective, a multi-dimensional approach is needed to determine the existing regulations associated with waste concrete disposal (e.g. landfilling restriction and/or taxation) to identify strategies to incentivise its use by the construction sector.
Feb 24, 2024 · Carbonation and microbially induced calcium carbonate precipitation were highly efficient and environmentally friendly for RA modification. Research progress in quantifying the environmental impacts associated with concrete from waste materials through the LCA methodology is presented.
