Cutbacks are form by the combination of asphalt cement with solvent (kerosene oil, diesel, gasoline etc…). In cutbacks asphalt cements are mixed up with solvents due to the requirement of resultant less viscosity fluid, so …

Pavement Binding Materials | Emulsion | Emulsion Binding Process | Emulsion Benefits | Types Of Emulsion
Materials which are being used for bond between different constituents of pavement, and that bond remains intact under different conditions. Binding materials actually increase the resistance between individual elements of mixture and increase its strength …
Continue readingConcrete Secant Modulus | Procedure | Benefits
A slope of the secant between two points on the curve is known as secant modulus. Secant modulus is applicable when concrete specimen shows non-linearity or where initial tangent modulus not gives too much required …
Continue readingModulus Of Elasticity | Concrete Modulus | Initial Tangent Concrete Modulus | Procedure
Elastic modulus of concrete is not easy to determine, because of non-linear behavior of concrete. Concrete is very strong in compression but very weak in tension and this is the main reason for non-linear behavior …

Poison’s ratio is the ratio between lateral strains and longitudinal strains. Poisson’s ratio, mathematically can be given as: V= – (lateral strain)/(longitudnal strain) When compressive force acts on a specimen then with the increase in …

Strain is the change in length as compared to original length that is before any variation. Strains in concrete are the reduction in volume of concrete after the application of loading then change in volume …

Stress is defined as; ” force per unit area.” Stress is the combination of loads like dead loads, live loads, wind loads that will acts on the structure during construction and during service life. Mathematically …

Mainly water reducing admixtures are divided into two categories depending upon the amount of dose being use in concrete and in result the decrease in the required weight of water. Low range plasticizers or regular …

A type of chemical admixtures that are used as a replacement of water is known as water reducing admixtures. By using that kind of admixtures, amount of required water for a workable concrete will be …

Air entraining admixtures affect the strength of concrete up to large extent. Air entraining admixtures have almost 15-25% effect on strength as compared to normal concrete. By using air entraining admixtures strength of concrete diminishes.
