75mm is the maximum clear cover of concrete
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
The maximum thickness of a reinforced concrete wall is 203 mm.
minimum curing period of concrete is 21 days and maximum is 28 days
POUR THE CONCRETE OVER THE BRICK
The area that 5 kg of concrete can cover depends on the thickness of the application. For a standard thickness of 10 cm (0.1 meters), 5 kg of concrete would cover approximately 0.05 square meters, given that the density of concrete is around 2,400 kg/m³. If the thickness changes, the coverage area will adjust accordingly. Always verify with specific mix designs for precise calculations.
There are several reasons, but corrosion protection and concrete spauling are probably the most important factors.

To build a patio cover on existing concrete, you can use anchor bolts to secure the cover to the concrete. First, measure and mark the placement of the cover on the concrete. Then, drill holes for the anchor bolts and attach the cover frame to the concrete using the bolts. Finally, install the roofing material to complete the patio cover.

POUR THE CONCRETE OVER THE BRICK
The clear cover is the concrete from outer face of stirrups to outer face of concrete. cover is provided to safe guard reinforcement from various environmental agents like moisture, harmful chemicals like sulphates and chlorides , carbonation due to atmospheric CO2 and moisture, chemical gases , near sea, sea water spray etc. Thickness of cover depends on the importance of structure, exposure conditions, fire rating required.- Satyanarayana, Hyderabaad,India

Minimum and maximum tolerances for concrete slump are established to ensure the concrete mix achieves the desired workability and strength. A minimum slump ensures that the concrete is fluid enough for proper placement and compaction, while a maximum slump prevents excessive water content, which can lead to segregation and reduced strength. Adhering to these tolerances helps maintain structural integrity and durability of the concrete in its final application.
To cover a concrete patio effectively, you can consider options such as laying outdoor rugs, installing interlocking deck tiles, or applying a concrete overlay. These methods can help improve the appearance and functionality of your patio.
