This test method provides procedures to be used for determining the effect of variables of composition, treatment, environment, or other factors in the bleeding of concrete. It is also permitted to be used to determine the conformance of a product or treatment with a requirement relating to its effect on bleeding of concrete.
Factors affecting durability of concrete. Durability of Concrete depends upon the following factors. Cement content. Mix must be designed to ensure cohesion and prevent segregation and bleeding. If cement is reduced, then at fixed w/c ratio the workability will be reduced leading to inadequate compaction.

Jul 30, 2015 · Consequently, as the W/C ratio increases, the porosity of the cement paste in the concrete also increases. As the porosity increases, the compressive strength of the concrete decreases. STRENGTH OF CEMENT V/S STRENGTH OF CONCRETE. It is not possible to design a concrete mix of high strength with cement .
Strength is an important characteristic of concrete but other characteristics such as durability, permeability, and wear resistance may be equally or more important. These may be related to strength in a general way but are also dependent on other factors. For a given set of materials, strength is inversely proportional to the w/c.
I've heard that the twocone fracture pattern is typical when compressivestrength cylinders are tested. Does that mean any other fracture pattern indies a testing or concrete problem?
