Why we provide PCC in Every construction & Notes - CIVIL ...
A strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 compressive strength at 28 days. Do not pour concrete in the pit from a height of more than 1.5 m. Do not allow extra cement mortar on top of PCC. for smooth finishing.

What does the 20 of the M20 concrete stands for? - Quora
The 20 stands for the minimum compressive strength of concrete at the end of 28 days in Newton per milimeter square. This is determined by batching six cubes of dimensions 150 mm each. The cubes are allowed to set and are cured and the compressive strength test is performed at the end of 7 days and at the end of 28 days.

Concrete Mix Design Calculation for M15 Grade as per IS ...
Step 5: Cement Content Calculation. From step 2, Water cement ratio = W/C = 0.57. From step 4, Water content W = 191.6 liters = 191.6kg. 191.6 / C = 0.57. Finally, C = 336.14 Kg / m 3 of concrete. But from table 5 of IS456-2000, Minimum cement content required for moderate exposure condition for M15 grade concrete is = 240 Kg/m 3 of concrete.

What is the use of PCC? – AnswersToAll
The main reason of providing PCC is to provide a rigid impervious bed to RCC in the foundation before starting any RCC or masonry work directly on the excavated soil, PCC is done to form a leveled surface and to avoid laying concrete on soil directly so as to avoid mixing with soil and also to prevent soil extracting …

Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

PCC Pavement – Pavement Interactive
A rigid pavement structure is typically composed of a PCC surface course built on top of either (1) the subgrade or (2) an underlying base course. Because of its relative rigidity, the pavement structure distributes loads over a wide area with only one, or at most two, structural layers (see Figure 1). Figure 1. Rigid Pavement Load Distribution.
