Lafarge South Africa is one of the major cement producers in Southern Africa and a subsidiary of the international Lafarge Group, which is not only the world leader in building materials but also a leader in its industry for sustainable development. The production of cement is a high energy, high greenhouse gas emission process. The Group has for many years transparently put into effect a wide spectrum programme of actions to reduce the environmental impact of its manufacturing and products, as well as promoting sustainable development in general.

The focus of future sustainable development is on the accelerating global trend to urbanisation, which is especially strong in South Africa, and the need to provide solutions for building better cities. Lafarge South Africa is in the unique position to create more housing in cities, more compact cities, more durable cities, better connected cities, and more beautiful cities, through having a strong presence in all its construction related business lines: cement, aggregates, readymix and plasterboard. This same expertise developed for cities, will also continue to improve development of South Africa's rural towns and villages, the cities of the future.

Lafarge South Africa is also actively concerned for the conservation of the country's wildlife heritage. As a major supporter of the world's first dedicated baby rhino orphanage in Limpopo Province, the company donates a portion of the proceeds from sales of its environmentally-friendly Buildcrete cement to the orphanage.


Helping to build better cities

Lafarge South Africa's premium technical cement, Powercrete Plus, and the innovative self-compacting AgiliaTM Vertical readymix concrete were used to construct the Fulton Award winning building, The Podium at Menlyn in Pretoria. These products have helped make this landmark building more beautiful and durable in keeping with our capital city.


An important example of an effective response to the trend for urbanisation is the 75 000 m² super-regional Mall of the North retail development, which is providing the residents of Polokwane in Limpopo with top-class city shopping and other amenities for the first time. The ground-breaking complex embodied sustainable, environmentally-friendly and energy-efficient features in its design, construction and operating systems.


Lafarge supplied extended lower-carbon footprint cements and, concrete for the construction of the Mall, which involved laying over 8 million bricks and placing 37 000 m³ of concrete. In addition. Lafarge Gypsum's 6,4mm Plasterboard was used extensively throughout the project, providing an ideal solution for quality, space efficient interior finishes.











Impressive achievements in emissions reduction

Lafarge reduced its global cement plant carbon dioxide (CO2) emissions by 20% per ton of cement compared with 1990 levels, a year earlier than the original 2010 target date. Recently, an ambitious revised target was set at a 33% per ton of cement reduction by 2020 compared with 1990 levels.

Greenhouse gas emissions from the cement process come from the high temperature decarbonisation of limestone, the primary raw material, and from the combustion of hydrocarbon fuels to heat the limestone. In South Africa, Lafarge recognised the potential of quality siliceous fly ash (‘fly ash'), a by-product of the Eskom pulverised coal fired power stations, as a cementitious extender. It was the first cement company, and still the only one, to offer a complete range of extended, more environmentally-friendly cements throughout all strength classes.  Slag, the by-product from the iron-making process in a blast furnace, is also used but is only available in limited quantities. The term ‘extended' refers to the replacement of a portion of the cement clinker with a suitable alternative material such as fly ash.


South Africa leading the way

Lafarge South Africa's pioneering development work on extended, lower carbon footprint cements has resulted in a major reduction in the company's CO2 emissions and a range of products that offer considerable performance benefits for customers compared with standard ordinary Portland cements. The company's highly regarded technical resource, Quality Department Southern Africa (QDSA), which provides technical and laboratory services to Lafarge's plants and customers in South Africa and sub-Saharan Africa. QDSA is also an advisor on extended cements to the rest of the international Group, which operates cement facilities in 48 countries around the world.


Looking at performance, all of Lafarge South Africa's fly ash based products contribute solutions for better concrete in the form of enhanced durability, long term higher strength gain, improved impermeability for more watertight concrete that also resists ingress of aggressive chemicals, as well as having a lower heat of hydration. These attributes contribute to low life-cycle maintenance and enhanced sustainability. The high fly ash content of the CEM IV general purpose cements mean they are in fact classified as Sulphate Resisting (SR) cements in terms of EN 191-1: 2011.


General purpose but superior performance
The general purpose Lafarge South Africa CEM IV cements Buildcrete and Durabuild have more   than 40% clinker replacement using fly ash extension. Locally, Lafarge is the only major company offering CEM IV products. From a global warming perspective, the formulations reduce emissions of greenhouse gases by more than 50% compared with standard ordinary Portland cement. Buildcrete is also an early strength gain ‘R' class cement, while its overall strength performance enables significant savings to be realised in cement usage compared with typical general purpose cements.








The versatile premium technical product

The company's premium technical extended cement, Powercrete Plus CEM II 42,5R, is widely used in the readymix and construction sectors. Even in the water infrastructure sector which traditionally uses CEM I products, Powercrete Plus was recently chosen for the construction of the Metolong Dam in Lesotho, based on its versatility and heat of hydration benefits.


A solution for precast concrete

Developed for the precast concrete industry, the high early and ultimate strength cement, Rapidcem CEM II, is the only extended 52,5MPa class cement in South Africa. A major endorsement of the product's innovative formulation was its selection to be used in the production of one million concrete rail sleepers for Transnet Freight Rail. After a demanding specialised testing programme and on-site trials, Rapidcem met the exacting German specifications and outperformed non-extended CEM I products. 


The first specialised road binder

Anticipating the priority that would need to be given to road infrastructure refurbishment and construction, Lafarge South Africa worked with road contractors to understand their needs and developed the country's first specialised road binder, RoadCem. The company is believed to be the first in Africa to introduce a dedicated, branded road binder cement. RoadCem is a CEM II cement with 35% clinker replacement using fly ash and slag.

Future trends

There is an increasing trend to sustainable development, whether in the form of stringent environmental specifications in infrastructure tenders or developers realising the long-term      financial and marketing benefits of Green Star rated buildings. Lafarge South Africa believes           that the cement solution lies in its innovative new generation extended products that provide  engineers with assistance in lowering the carbon footprint of their designs, as well as the opportunity to design for strength at later ages, enabling reduced cement requirements.
