                     the Lafarge brand name stands for
                     leadership in building materials:
                     leadership that has been achieved
                     by applying the knowledge within the
                     Group to bring innovative products
                     and solutions to satisfy the needs of
                     our customers.

What makes a
Good Cement?
At Lafarge, cement is not a commodity but the exciting
bond that enables the creation of luxury apartment blocks
reaching a mile into the sky, huge sports stadiums, graceful
bridges, massive dams, elegant sculptures or just a simple
dwelling that you can call home!

We involve ourselves in the work of architects and developers and
pioneer cements that extend the boundaries of design. We talk to
new construction entrepreneurs and DIY homeowners and innovate
more user-friendly, efficient products and support services. We work
at building long-term business relationships. We listen to the market’s
needs and innovate new products and services that differentiate us
from our competitors.

Customers have the basic protection in South African law that, with the
phasing out of the SABS Mark, eventually all bagged cement sold in
the country will have to display a Letter of Authority number. This will
give the assurance that the cement has been formulated to achieve
the strength specified on the bag.

Our	cements	are	designed	to	give	you	more:	
•	   Industrial	control	standards	that	ensure	consistent	high	quality.
•	   Product	performance	and	handling	properties	that	exceed	your	
     expectations.

Lafarge	products	are	backed	by	service:	
•	   Access	to	technical	advice	from	our	Quality	Department	
     Southern Africa.
•	   Innovative	general	support	service	through	our	Customer	Care	
     Centre, “CELIA” (Customer Excellence at Lafarge in Action).
     CELIA has been set up to provide customers with a user-friendly
     channel for quick and effective resolution of any problems.




     A	word	of	advice	from	an	experienced	builder:

     “Save on the cost of your building materials by good
     control, never by lowering quality – it is a false economy!”

Misconceptions
about Cement
Myth: “It says 50kg on the bag, so it must contain 50kg of
      cement!”
Fact: It should contain 50kg but it is a case of ‘Buyer Beware’!
       Not all companies have accurate enough equipment or the
       management systems to achieve this.
       Buy a well-known brand name product. The Lafarge name
       is your guarantee: our Lichtenburg Cement Works has also
       been certified to display the SABS e-mark on its cement
       packaging, assuring buyers of the mass of cement they have
       paid for.

Myth: “Cement extenders reduce the quality of a cement.”
Fact: On the contrary, research and development over the
       last thirty years has shown that, formulated correctly,
       quality extenders significantly improve many performance
       characteristics of hardened concrete, while making concrete
       and mortar mixes more user-friendly for the builder.

Myth: “Any cement will do for general construction work: just go
      for the cheapest!”
Fact: Why risk having a poor concrete job? Ask your builder’s
       merchant for advice. A good quality branded cement can
       make concrete and mortar mixes that are easier to mix
       and place. The finished concrete is also stronger and more
       durable.

Myth: “A good mortar depends only on how well you mix the
      materials.”
Fact: Thorough mixing of the materials until a uniform colour
       is achieved is always essential to avoid a patchy finished
       appearance and areas of weak strength. However, a good
       quality cement, especially one based on fly ash (e.g.
       Buildcrete), makes mixing easier. The resulting more
       workable, ‘buttery’ mix leads to a higher work rate.

Myth: “The strongest concrete is made with pure cement, not the
      cements blended with extenders.”
Fact: Properly cured concrete containing quality extenders
       will achieve a more durable and higher ultimate strength
       concrete.

                              for Success
Whether building a dream home or furthering a business,
success comes from paying attention to some basic principles:
•	 Use	reliable	quality	materials                •	 Be	absolutely	consistent	with	mixing	your

•	 Plan	your	work	carefully                      •	 Think	SAFETY	before	you	start	any	job

Solid Foundations
Out of sight, out of mind! So often foundations are subjected to cost-cutting
and	yet	are	so	important	for	building	a	sound,	long-lasting	structure
•	   It	pays	to	employ	a	specialist	to	check	the	soil	conditions	of	the	site
•	   Prepare	an	area	for	mixing.		If	there	is	no	concrete	surface,	use	
     a sheet of metal to avoid the contamination and water variation
     problems with mixing on the ground
•	   Use	a	good	quality	general	purpose	cement.	(Buildcrete will give a
     good workable mix for easier handling, placing and finishing. Buildcrete
     mixes also develop their strength quicker – saving time and money)

industry searching for ways to allow people to enjoy
the benefits of economic growth, while minimising
the damaging impact on our earth. The Lafarge name
