US: Lehigh Cement and Argos USA have agreed to pay a US$1.5m fine for alleged Clean Air Act violations at the Martinsburg cement plant in West Virginia. Argos has owned the plant since December 2016 and Lehigh Cement was the previous owner. The violations occurred from 2013 to 2016. Neither Lehigh Cement nor Argos USA admitted liability for the alleged violations as part of the settlement.

The Environmental Protection Agency (EPA) cited the companies for various Clean Air Act violations based on responses to EPA information requests and data collected and reported under the plant’s permit. These included exceeding particulate matter emissions, non-compliance with opacity testing, failing to comply with requirements for operating a kiln with dioxin/furan emission limits, failing to perform required stack testing on a kiln’s exhaust in a timely manner and other violations.

Trinidad & Tobago: The Caribbean Court of Justice (CCJ) has ruled that Rock Hard Cement does not have to pay more than a 5% tariff on imported cement. The regional court was ruling on the duty liable for ‘other hydraulic cement,’ according to the Jamaica Gleaner newspaper. Rock Hard Cement’s competitor Trinidad Cement and its subsidiaries had argued that such imports be liable to a 60% import rate that the importer had previously paid due to Barbados’ exemption from the region’s Common External Tariff (CET) in 2001 and its subsequent re-entry in 2015.

Philippines: Republic Cement has launched Kapit-Balay Masonry Cement. The type S high-strength masonry cement product is intended for plastering, brick or block laying and block filling. The product is being produced at the company’s Danao plant in Debu.

Mauritius: Lafarge Mauritius has launched Lakaz Mazik, a cement bag that dissolves in a concrete mixer. The bag has been developed by Sweden’s BillerudKorsnäs, according to the L’Express newspaper.

US: Illinois State University has been awarded a US$15,000 grant by the Environmental Protection Agency (EPA) to research the use of recycled glass as a substitute for Ordinary Portland Cement and fly ash in controlled low-strength material (CLSM). CLSM, also called flowable fill, is a cement-based construction material commonly used for backfilling trenches or other excavations, as well as soil-stabilisation. It can be produced at any ready-mix concrete plant by mixing cement, fly ash, sand and water in the correct proportions.

Project lead Pranshoo Solanki said that preliminary results are promising, and show that required flow and strength can be met by replacing cement and fly ash with recycled glass powder.

The EPA grant is for phase one of the recycled glass project for research at the laboratory scale. Funding for phase two will then be sought to test the product in real-world trials.
