OUR PRODUCT RANGE
Cement is one of the most important building materials in the world and has been used for millions of years. It is created by combining calcium, silicon, aluminium, iron and other ingredients such as limestone, clay and sand. It is the main component of concrete and is essentially a substance used in construction to bind materials together such as sand and aggregate. Cement is often lime-based and can be characterized as either hydraulic or non-hydraulic. Hydraulic cement has the ability to set and harden very quickly when mixed with water. It is used to prevent leaks in concrete and masonry structures and therefore incredibly useful in the construction of swimming pools, drainage systems, foundations and fountains for example. Non-hydraulic cement reacts with carbon dioxide instead of water and is resistant to attack by chemicals after setting. There are many different types of hydraulic and non-hydraulic cement, each with its own properties, uses and advantages, and each variety that is manufactured has to comply with specific industry standards and norms. Cement is also graded based on its individual compressive strength. LafargeHolcim has 226 cement and grinding plants worldwide with 56 133 employees.
Saruji ni mojawapo ya nyenzo muhimu zaidi za ujenzi kote duniani na imetumiwa kwa mamilioni ya miaka. Saruji huundwa kwa kuchanganya kalsiamu, silikoni, aluminiamu, chuma na viungo vingine kama vile chokaa, udongo na changarawe. Saruji ndiyo sehemu kuu ya zege, na kimsingi ni nyenzo inayotumiwa katika ujenzi wa kunatisha nyenzo, kama vile changarawe na mawe. Mara nyingi, saruji hutengenezwa kwa chokaa na inaweza kufasiliwa kuwa saruji ya maji au isiyo ya maji. Saruji ya maji ina uwezo wa kuwekwa na kukauka haraka sana ikichanganywa kwa maji. Saruji ya maji hutumika kuzuia kuvuja katika miundo ya zege na uashi, na hivyo ni muhimu sana katika ujenzi wa vitu kama vile mabwawa ya kuogelea, mifereji ya maji, misingi na chemchemi. Saruji isiyo ya maji huchanganywa na kaboni ya dioksidi badala ya maji, na ukinzana na kemikali baada ya kuwekwa. Kuna aina nyingi za saruji ya maji na isiyo ya maji, na kila moja ina sifa, matumizi na manufaa yake maalum, na kila aina inayotengenezwa inapaswa kuzingatia viwango na kanuni maalum za sekta ya ujenzi. Saruji hukadiriwa kulingana na uwezo wake wa kubana. LafargeHolcim ina viwanda 226 vya saruji na kusaga mawe kote duniani, vinavyowaajiri watu 56,133.

BIDHAA ZA SARUJI
Lafarge Tanzania imekuwa ikiitengenezea nchi hii na mataifa jirani bidhaa yetu ya saruji ya Tembo, ambayo ni ya kiwango cha kimataifa, kwa zaidi ya miaka 30. Ofisi yetu ya kuu na kiwanda jumuisha kikamilifu zipo Songwe, Mkoa wa Mbeya, Kusini Magharibi mwa Tanzania.
Bidhaa za saruji ya Tembo huyalinda mazingira kwa kuwa zinazalisha kiwango kidogo sana cha kaboni ya dioksidi. Bidhaa hizi ni thabiri na za gharama nafuu, kwa hiyo hulinufaisha zaidi soko la Afrika. Poda hizi zote za saruji zina sifa na matumizi ya kipekee.
AGGREGATES
Aggregates are fragments of rock measuring from 0.08 to 80 mm in diameter. Typically the most common size of aggregate used in construction is 20mm. They are a vital component in construction and are extracted from quarries, crushed and then calibrated. They appear in a range of products such as gravel, sand and crushed rock.
Aggregates are the most mined materials in the world and have many uses and functions in residential and commercial construction such as support, structural filling, draining, reinforcement and aesthetic applications. They are commonly used as a low-cost extender that binds with cement or asphalt to form concrete and used in the construction of houses, bridges and other similar structures.
MAWE
Mawe haya yana kipimo cha milimita 0.08 hadi 80. Kawaida, ukubwa wa kokoto unaotumika zaidi katika ujenzi ni milimita 20. Mawe haya, ambayo hufukuliwa kwenye machimbo, kusagwa na kupimwa, ni muhimu katika ujenzi. Mawe haya hufanywa nyenzo mbalimbali kama vile kokoto, changarawe na mawe yaliyosagwa.
Mawe ndiyo madini yanayochimbwa kwa wingi zaidi kote duniani, na huwa na matumizi mbalimbali katika ujenzi wa majengo ya makazi na ya biashara. Matumizi haya ni pamoja na kujenga mihimili, kujazia majengo, kujenga mitaro, kumarisha na kurembesha majengo. Mawe haya hutumika sana kama nyenzo za bei nafuu za kuchanganywa na saruji au lami kuunda zege inayotumiwa katika ujenzi wa nyumba, daraja au miundo mingine kama hii.
