The Importance of Concrete Mix Design Concrete Supply Co.

Concrete mix design involves a process of preparation in which a mix of ingredients creates the required strength and durability for the concrete structure. Because every ingredient in the mix consists of different properties, it’s not an easy task to create a great concrete mix. It is imperative that all ingredients be tested to determine their physical properties and the bearing capacity ...

The surface of the most widely used exposed concrete can, however, be finished in many different ways: a popular way of changing the visual appearance of concrete is to skim the top layer of the concrete's mortar. This gives the concrete a more or less developed structure, a kind of relief on its surface. Secondly, the surface's texture changes, as the materials added to the concrete emerge ...

Sulfate attack in concrete and mortar. Sulfate attack can be 'external' or 'internal'. External: due to penetration of sulfates in solution, in groundwater for example, into the concrete from outside.

20/06/2020  Normally the concrete slab for such tanks have a very high requirement of crack control so i doubt that if thats not considered in design. I would recommend first check the design of the wall pocket (if the leak is there) and confirm with the site notes if the seal is provided. The remedial measures can only be suggested once the cause is known. There are several options which can be adopted.
