SRC is defined as the hydraulic bonding grey fine powder which is the result from crushing a dry mi
x made of clinker and gypsum.
Adding and mixing water to it harden this grey fine powder, and this is what makes it resistant to water and able to bare compressive stresses, as well as resistant to sulphates that exist in soil, such as clay soil.
In this type of cement it is necessary to decrease the ratio C3A less than 3.5%, because this component reacts with Ca SO4, which exists in soil or water. The result of this reaction is called Etringite, which is aproximately 277% of the volume of C3A, and causes cracks that leads to concrete failures.
Part of the sulphate resistance cement composition is an adittion of Fe2O3 mixed with row materials. Fe2O3 facilitates the reduction of Etringite and increases C4AF, which does not have the property of expansioning volume; so it has higher resistance against sulphates.
Uses and applications:
It can be used in all concrete constructions such as reinforced concrete foundations, sewage drainage tanks, bridge foundations, piles...which are exposed to be directly affected by sulfates.
It can also be used in sewage concrete pipes and lining steel pipes.
Shelf time:
6 weeks, since the production date.
Safety recommendations:
It is recommended to follow the coming instructions:
Avoid the contact of the cement with the eyes and the skin since it may cause allergic reaction.
Use gloves and glasses to protect hands and eyes in case of spry applications, or manual mixings.
It is no poison, according to all international specification for safety and health.
Packing:
Bags: 50 Kg/bag
Jumbo plastic bags:500 Kg/bag1000 Kg/bag1500 Kg/bag
It is also available in bulk
Storage:
It is recommended to follow the coming instructions:
Storage should be done in a dry place and away from ground moisture.
It is preferable to store it on wooden bases.
Cement should be covered to avoid the rain.
It is recommended not to pile up any more than ten bags, some on others.
How to clean the cement remains of the used tools:
Before setting: by using clean water.
After setting: by using mechanical methods.
Environment concept
It is advised and recommended to follow local environmental instructions.
