India: The government of Andhra Pradesh will subsidise the purchase of cement for 122,000 new houses in rural Guntur district under its Housing for All scheme. The Hans India newspaper has reported that builders have laid the foundations of 14,000 of the properties, and will have completed a further 46,000 by the end of the working day on 9 July 2021. District revenue collector Vivek Yadav said that the administration will announce further housing projects under the scheme after builders complete 116,000 units.

Malaysia: Buddhist monks at the Dhamma Sakyamuni Caves Monastery have filed a petition to the state government of Perak to have the site recognised as a place of worship and the local Mount Kanthan area approved as a national heritage site. Mongabay has reported that the caves lie in YTL Cement’s Mount Kanthan quarry. The religious site is located on the still unquarried southern face of Mount Kanthan.

YTL Cement started eviction proceedings at the site in late 2020. It said, “Contrary to what has been claimed by irresponsible parties, we have co-existed harmoniously with the local community. The real issues at hand are safety and the sanctity of the law.” It added with regard to the safety issue, “As the rightful owner of the land, we are responsible for all that occurs on it. We cannot stand by the misleading of the public nor allow such negligence.”

A predecessor company of YTL Cement leased the site in the 1960s. However, the monks allege that they were using the area several decades prior to this. The relationship between both parties broke down in 2013 when the cement company started to ask the monks to leave the monastery during rock blasting.

Kenya: Nairobi Business Ventures (NBV) says it intends to buy 11.33 hectares of land in Machakos, near Nairobi, from its subsidiary Shreeji Enterprises Kenya to build a new cement grinding plant. It plans to invest US$140m in the project according to the Business Daily newspaper. A feasibility study for the construction of the plant has been concluded and the preliminary work to establish the plant is currently being conducted.

The former shoe manufacturer announced plans in late 2020 to build a 1Mt/yr cement plant following its acquisition by UAE-based Delta International Holding. The project will run as a grinding unit first before moving to clinker production at a later stage. The company also plans to diversify into vehicle and aircraft maintenance.

Austria/Australia: Refractory producer RHI Magnesita and Calix say they have started a memorandum of understanding to develop a flash calciner for use in the production of refractory materials, to enable CO₂ separation for either utilisation or storage. The companies have agreed to run studies up to and including basic front-end engineering and design for a commercial-scale demonstration facility at an RHI Magnesita site.

RHI Magnesita and Calix started discussing a collaboration in early 2019. The application of Calix's technology to refractory products has been the subject of pilot scale test work during 2020, with larger scale test work currently underway.

Luis Bittencourt, chief technology officer of RHI Magnesita said, "We are pleased to be working with Calix on this project, which is a key part of the research and development programme on CO₂ emissions reduction that we are carrying out over the next five years. Together with our partners at Calix, we are seeking to develop new technologies for the capture, storage and utilisation of CO₂ that would otherwise be emitted during the refractory production process." Phil Hodgson, the managing director of Calix added that the company was also looking at strategic opportunities in its magnesium oxide businesses.

India: Researchers at the Visvesvaraya National Institute of Technology in Nagpur, Maharashtra, have shown in laboratory studies that an enzyme called urease found in watermelon seeds can strengthen cementitious materials and repair cracks in concrete. The Times of India newspaper has reported that the study found around a 22% increase in compressive strength, a 19% reduction in water absorption and improvements in durability. It is hoped that the food industry waste product could potentially be used to replace chemical admixtures commonly used in concrete production. Field studies are now set to follow.

Study leader associate professor Madhuwanti Latkar said, “Watermelon seeds are magic beans when it comes to importing strength to cementitious materials.”
