Holcim (Strong Structure), a Portland Composite Cement (PCC) complies with BDS EN 197-1:2003, CEM II/B-M (S-V-L), 42.5N standard. The usage of this type of cement started from last few decades in Bangladesh. Holcim (Strong Structure) is suitable for all types of construction works as raw material of concrete and mortar. Being PCC types cement containing PFA & slag, Holcim (Strong Structure) provides long term strength development advantage in concrete.
Long Term Strength: The Pozzolanic characteristics and Latent Hydraulic reaction initiated by Holcim (Strong Structure) helps to gain strength beyond 28 Days.
Improved Workability: The particles of PFA and slag presence in Holcim (Strong Structure) provide a ball bearing mechanism to concrete aggregates. This increases the workability of the concrete and eases placing.
Chemical Resistance: Usage of Holcim (Strong Structure) produces less permeable and denser concrete which restrict the penetration of moisture and air inside finished concrete. Thus reinforcements used in RCC are safe from corrosion effect
