Al Asas cement
CEM I – 42.5 N – SRC
-
High strength Grade 42.5N
-
High sulfate resistance
-
Recommended for foundation elements, raft footings and piles
-
Recommended for all substructure elements such as irrigation and sewage systems which are exposed to severe sulfate salt attacks from ground water.
Al Asas Cement CEM I – 42.5 N – SRCSpecifically designed to be used for sub based structures where the soil is rich with Sulphur salts, whether clay or underground water. Al Asas SRC Cement consists of 95% SR clincker, protecting the structure from the deformation of concrete and rebar corrosion, which is mandatory even with the use of insulating materials. Using Al Asas Cement is ideal for safety and durability of the structure elements. |
