Type A and D materials are generally considered high -quality base since crushed materials have, in general, higher stability than rounded materials. Type A and D are often used in combination with Grade 1 –2, which has the most stringent material requirements. Type D allows the use of Type A or crushed concrete.

The UK cement industry has agreed to reduce its primary energy consumption by 25.6% per tonne of cement produced by 2010, from a 1990 baseline. In return, the industry receives an 80% rebate from the Climate Change Levy. The reductions are phased over a number of years (Table 2.2.1) MINERAL PROFILE: CEMENT RAW MATERIALS 2: Extraction and processing

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
