Figure 1 Schematic diagram of the cement production process Transition of specific thermal energy consumption for cement production The specific thermal energy consumption for cement production in Japan fell drastically in the 1970s and 1980s (see figure 2) as older kiln systems were replaced by the suspension preheater kiln (SP kiln) or suspension preheater kiln with a precalciner • Chalk is porous and often has high moisture content that leads it to its use in the 'semi-dry/wet' manufacturing process of making cement This particular process represents some 16% of total production Shale • Shale is a pure sedimentary rock made of very fine silt clay and quarz Shale falls in the category of mudstones

Manufacturing process

The raw materials needed to produce cement (calcium carbonate silica alumina and iron ore) are generally extracted from limestone rock chalk clayey schist or clay Suitable reserves can be found in most countries These raw materials are extracted from the quarry by blasting They are then crushed and transported to the plant where they are stored and homogenized

The hazards of wet cement are due to its caustic abrasive and drying properties Wet concrete contacting the skin for a short period and then thoroughly washed off causes little irritation But continuous contact between skin and wet concrete allows alkaline compounds to
