Cement - Import export

Cement is used for various construction works, for example, for pouring foundations, or, as a fixing mortar, for brickwork. In addition, cement is used to produce concrete and is used to make reinforced concrete. The use of reinforced concrete has spread in both industrial and civil construction.

Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process Sack kraft paper is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp Fully bleached kraft pulp is used to make high quality paper where strength, whiteness, and resistance to yellowing are important Applications: Kraft paper bags Plastic-hazard-free paper in paper sacks for cement, food, chemicals, consumer goods, flour bags Electrical insulation in large oil-filled transformers Paper grocery bags, multiwall sacks, envelopes and other packaging An inexpensive material for lining particle boards Properties: CAS Number 65996-61-4 Grammage (GSM) range 40-135 g/m2 Appearance poly coated natural kraft paper Color brown Odor none Auto ignition temperature 232-300°C

Burnt lime Calcium oxide (CaO), commonly known as quicklime or burnt lime, It is a white, caustic, alkaline, crystalline solid at room temperature Calcium oxide that survives processing without reacting in building products, such as cement, is called free lime Industries: Glass and ceramics production of glass, calcium aluminate cement, and organic chemicals production of aerated concrete such as blocks with densities of ca. the major use of quicklime is in the basic oxygen steelmaking (BOS) process the quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag Properties: CAS number 1305-78-8 WE number 215-138-9 Chemical formula CaO Molar mass 56,08 g/mol Customs tariff code 28259019 pH 12,3

Industry floors, concrete block-systems, plant pots, bicycle paths, clinkers, tiles, flags, joint wet mortar, cement adhesive, mineral paints,… NATURAL OXIDES: yellow, red, brown, black SYNTHETIC IRON OXIDES: yellow, red, brown, black DRAGON PIGMENTS: blue, green, grey CHROME OXIDE GREEN COBALTOXIDE BLUE CARBON- or PITCH-BLACK (limited) TITANIUM DIOXIDE WHITE A pigment is a substance that has the capacity of colouring a certain carrier (cement, plaster, synthetic fibres, paint, …). Contrary to dyes, pigments are insoluble. Therefore, pigments remain under the form of small particles and will just be dispersed in the carrier and so colouring the carrier. The colouring capacity of the pigment depends on the fineness of the particles composing the pigment. In general we can say that the finer the particles are, the higher the colouring capacity of the pigment will be. A pigment is only suitable for certain applications. The pigment shouldn’t react with the carrier.
