alccocrete (HS)
High Strength Ready Mix Micro-concrete
Description: Typical Uses:

alccocrete (HS) is a versatile, high strength,  Restoration of deteriorated reinforced

non-shrink cementitious micro-concrete concrete components such as slabs,
requiring addition of only water to produce a beams, columns, and walls
free flowing mix. It ensures clean and efficient  Where access is restricted, and
application process. It is composed of compaction cannot be achieved through
cement/ cementitious materials, “classified vibration
engineered sand,” and additives. It is designed  Enhancing the load-bearing capacity and
for repair of damaged reinforced concrete reinforcing vertical structural elements
elements like columns, beams & structural through the process of RCC column
elements, especially areas that are not easily jacketing
accessible for proper placement of concrete  Application on slender structural elements
like micro-piles
