This liquid mix does not differ much in process and result from the dry mixture but it does have a positive impact environmentally. This comes in the form of a reduction of carbon footprint. Due to the liquid state, the mixture can be transported from the quarry to the cement manufacturing plant without the use of trucks or fuel powered vehicles.

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill. The firing process consumes significant quantities of fuel, usually coal or petroleum coke.

If the cement industry were a country, it would be the third largest emitter in the world. In 2015, it generated around 2.8bn tonnes of CO2, equivalent to 8% of the global total – a greater share than any country other than China or the US.. Cement use is set to rise as global urbanisation and economic development increases demand for new buildings and infrastructure.
