Material Production
ESCC has recently diversified into production of Lightweight concrete. This material has proved to be an effective material with predictable characteristics used for decades in the construction industry.
Light weight concrete applications
-
Screeds and walls where timber has to be attached by nailing.
-
Casting structural steel to protect its against fire and corrosion or as a covering for architectural purposes.
-
Heat insulation on roofs.
-
Insulating water pipes.
-
Construction of partition walls and panel walls in frame structures.
-
Fixing bricks to receive nails from joinery, principally in domestic or domestic type construction.
-
General insulative walls.
-
Surface rendered for external walls of small houses.
-
It is also being used for reinforced concrete
Advantages of using Light weight concrete
-
Reduced dead load of wet concrete allows longer span to be poured unpropped. This save both labor and circle time for each floor.
-
Reduction of dead load, faster building rates and lower haulage and handling costs. The eight of the building in term of the loads transmitted by the foundations is an important factor in design, particular for the case of tall buildings. The use of LWC has sometimes made its possible to proceed with the design which otherwise would have been abandoned because of excessive weight. In frame structures, considerable savings in cost can be brought about by using LWC for the construction floors, partition and external cladding.
-
Most building materials such as clay bricks the haulage load is limited not by volume but by weight. With suitable design containers much larger volumes of LWC can haul economically.
-
A less obvious but nonetheless important characteristics of LWC is its relatively low thermal conductivity, a property which improves with decreasing density in recent years, with the increasing cost and scarcity of energy sources, more attention has been given the formerly to the need for reducing fuel consumption while maintaining, and indeed improving, comfort conditions buildings. The point is illustrated by fact that a 125mm thick solid wall of aerated concrete will give thermal insulation about four times greater than that of a 230mm clay brick wall.
