Project Template Please provide us with the information about a potential program CDM project by filling the form below. Kindly send it back to us by Friday March 9, 2007. Thank you. 1. Name of the project

Investigation, survey of energy using efficiency

in cement production

2. Project type or sector 3. Host country 4. Project location 5. Size of the project, e.g. the number of participating households, provinces, sites, etc. 6. Project description

1.

Cement production technology

Cement classification bases: - Substance composition; - Clanke type; - Use significance; - Durability; - Velocity of compression; - Time of curdling; At present in Vietnam, cement has been produced accord dry and wet methods Technolo gy

2. Use input material

Material has mineralization components of clanke ens get cement with intensity minimum is 250 kg/cm2 after 28 follow TCVN 4029-4432-85, cement clanke has techno parameter: Saturated coefficient: KH = 0.84 - 0.87 Silic Modun: n = 2 - 2.4 Alumin Modun: p = 1.2 - 1.7 Mineralization components: C3S = 45 - 50% C2S = 27 - 32% C3A + C4AF = 20 - 24%

Raw materials use to produce clanke, which is ma contain calcium as limestone and pottery material as clay material is mixed water (wet technology) to form cement mo don’t mix water (dry technology) to form dry speck.

3. Use energy

In cement manufacture, 60% price is spending on ener stages: 3.1. Energy in manufature: - Grind material - Drying - Baking - Grind clanhke - Packing - Transport in factory - Mix material 3.2. Spending on energy includes: - Fuel component - Dry and wet production technology

- Production stage - Equiment Status - Management Status

4. Nowaday Viet nam has some specific norms for ce production

7. Project implementation structure 8. Project time 2007 -2008 schedule 9. Characteristics Cement of a technology to be employed

production technology

Nowaday, Cement Production Technology in Vietnam in 3 main stages: Material preparation stage

Clanke baking stage

Grind, paking stage

aterial preparation stage: To put material (limestone,

adjustment additive, mineralization additive) into a fact material mixing silo;

Japanese Ministry of Environmental Study on the Program CDM

- Clanke baking stage: From material powder removing st uniform mixing silo to clanke silo; - Grind, packing stage: From clanke removing stage in silo to finished product
