Factors Affecting The Compressive Strength Of The Concrete

It has been observed that the compressive (crushing) strength of concrete is influenced by a huge number of factors. some of the most important factors are: i. type of cement: the composition, quality and ‘age‘ of the material which is used in the manufacture of cement that have been stored for the considerable time make concrete of lower.It is the most important factor for gaining the strength of concrete. the lower w/c ratio leads to a higher strength of concrete. generally, the water/cement ratio of 0.45 to 0.60 is used. too much water leads to segregation and voids in concrete. the water/cement ratio is.

Factors That May Affect On The Strength Of Cement Concrete

Sep 13, the factors affecting the strength of concrete are mentioned below. these factors can be either dependent or independent of each other when comes to the concrete strength. most of the factors are interrelated in certain means. the primary factor that has a higher influence on the strength of the concrete is the mix design factors. each of them is mentioned and explained in detail one by.Sep 18, home blog factors that may affect on the strength of cement concrete. factors that may affect on the strength of cement concrete. ... maximum particle size of the crushed stone should be under 30 mm and sandstone no more than 20 mm. crushing value of the coarse aggregate should be under 12%, no more than 20%. coarse aggregate needle.

Factors Affecting Strength And Workability Of Concrete

Factors Affecting Strength And Workability Of Concrete
A Study Of Factors Affecting The Flexural Tensile Strength

Strength and workability are both dominating factors in the making of concrete. strength can be increased by increasing cement content but this in fact reduces the workability. moreover,the water content can be increased for better workability, but this affects the strength. hence,a perfect balance is to be maintained for both strength and.Strength of concrete. the effect of the factors like age and con-finement of concrete on flexural strength has not been investi-gated properly and proper inter-dependency of various factors that affect the flexural strength has not been co-related. the effect of confinement on flexural tensile strength.
