Cuba: The Ministry of Finance and Prices has published a list of prices for a range of products, including cement, that are sold in state-run stores and agricultural markets. The ministry says that the initiative is intended to evaluate the local market at the municipal level in response to concerns about inflation following a government-mandated salary increases, according to 14ymedio. Shops that violate the regulated price lists may face sanctions.

Cuba: The University ‘Marta Abreu’ of Las Villas (UCLV) has started operating a 7t/day limestone calcined clay cement plant. The unit will be run by the Geominera del Centro Company, according to the Cuban News Agency. Building materials produced at the plant will be used locally.

Fernando Martirena Hernández, director of the Centre for Research and Development of Structures and Materials (CIDEM), said it was the first plant producing low carbon cement in the world. The project is a collaboration between the university and the Swiss Agency for Development and Cooperation as part of the LC3 project. Similar plants are planned for 18 countries including India, China, Indonesia, Thailand, Guatemala, Mexico, Ecuador, Colombia, Peru, Ivory Coast, Cameroon and Senegal.

Cuba: The Nuevitas cement plant expects to produce 0.12Mt of cement in 2018. Nearly 80% of this output will be used to build houses, according to the Adelante newspaper. The plant serves the Camagüey province as well as Las Tunas, Granma and Ciego de Ávila.

Cuba: A new railway cement terminal is being built at Ciego de Ávila. The unit will have five silos with a total storage capacity of 1600t, according to the Invasor newspaper. The terminal should be compelted by the end of 2018. The site is intended to support hotel construction, infrastructure projects and general housing in the region.

Cuba: The Nuevitas cement plant will test LC3 cement, according to the Adelante newspaper. LC3 is a blend of limestone and calcined clay that reduces the amount of clinker used. The plant is one of three units in the country earmarked for upgrades in 2018.

Cuba: The government has allocated over US$26m to upgrade three of the country’s cement plants. Pavel Cansino Ávila, deputy director of the Cement Business Group, told the Cuban News Agency that the Santiago de Cuba plant, also known as the José Mercerón plant, will be replaced with a new plant. The new unit is scheduled to be built by 2021 and it will have a production capacity of 1.2Mt/yr. The Siguaney plant and the Nuevitas plant will also be upgraded in 2018.

In 2017 the six local cement plants were unable to meet a government order of 1.57Mt of cement. Failures occurred due to lack of maintenance budget for the plants, issues due to a lack of packaging materials and logistics issues with deliveries.

Cuba: The Punta Alegre gypsum mine near Ciego de Ávila supplied over 56,400t of gypsum to the local cement industry in 2017. The mine mainly supplied Cementos Cienfuegos, according to the Invasor newspaper. Despite the disruption caused by Hurricane Irma in mid-2017 the mine beat its annual production target of 50,000t. The unit installed a new mill from Chinese suppliers that increased its production capacity to 100t/hr in 2015.

Cuba: Cementos Cienfuegos has gradually restarted production following Hurricane Irma hitting the island in early September 2017. Electricity was restored to the site on 14 September 2017 enabling the cement mills to be operated. The kiln was ignited on 19 September 2017, according to the 5 de Septiembre newspaper. Components damaged by the storm included the insulation covering electrofilters on the plant’s tower, broken power cables and a breach to a water dyke near the site.

Cuba: The Cuban cement industry is operating at a 58% capacity utilisation rate, according to the CiberCuba website. The low rate has been blamed on logistic and electricity supply problems.

India: Swiss, Indian and Cuban researchers have come together to develop limestone calcined clay cement (LC3), which can help reduce the carbon dioxide emissions of cement by almost 30%.

"The LC3 project is an example of scientific and technical collaboration between Switzerland and India. The innovative cement production process on which these institutions are working is of great economic and environmental significance," said Switzerland Ambassador to India Linus von Castelmur.

The LC3 is a synergetic hydration of clinker, calcined clay and crushed limestone to achieve the performance required from commercial cements, with clinker factors as low as 0.40. It also costs less than traditional types of cement.

"The testing and application phase is over, now it has to pass through standardisation committee before it is accepted by the industries. The research that has been done will not be patent protected but available to everyone," said Castelmur.
