INSEE RAPIDFLOW is an Ordinary Portland Cement (OPC) especially designed to produce unmatched early compressive strength, ideal for large-scale infrastructure projects such as bridges, roads, and high-rise buildings.
INSEE RAPIDFLOW addresses the demand for accelerated speed of construction with today’s rapid pace of development, reducing construction as well as project lifecycle time with rapid strength development. This also makes INSEE RAPIDFLOW ideal for precast concrete elements for high-rise structures, ensuring early occupancy and early returns.

INSEE RAPIDFLOW is compatible with:
INSEE RAPIDFLOW is especially designed for civil engineering and structural concrete applications,
which include:
Eg: Slab construction with G30 concrete with an expected slab cycle of 7 days for 30 nos. of slabs. Formwork removal is carried out after 3 days, once the required strength of the concrete is achieved. Early strength development of INSEE RapidFlow produces the required strength within 2 days. This results in a 30-day reduction of the total project lifecycle, and the elimination of related direct and indirect labor and operational costs.
The high early strength development of INSEE RAPIDFLOW contributes to significantly reducing the overall construction cycle of projects, and thereby also decreasing project cost.
Its high quality clinker allows for rapid setting times and high early strength development in concrete. This property is beneficial for time-critical constructions as well as for precast concrete elements.
