Abstract EN
This study is directed to evaluate the ability of using cone penetration test as a simple method to investigate the consistency level of fresh concrete.
A cone of 30 apex angle attached with different load values was used.
Eighteen concrete mixes divided into three groups were conducted.
Three types of coarse aggregate were tried.
Crushed dolomite, round gravel, and crushed basalt all of 20 mm maximum grain size were investigated.
For each type of coarse aggregate, six levels of concrete consistency calibrated by standard slump test were tried.
For the investigated mixes and at a specified consistency level, the displaced volume values were directly proportional to the applied load.
The inclination of this relation is termed as the displaced volume rate (D.V).
The results of cone penetration were analyzed and compared to the corresponding slump test values.
The displaced volume per unit mass, bearing strength, as well as shear yield strength were the evaluated properties.
The results introduce the cone penetration test as a simple instrument that could be adopted either at a laboratory or at site to evaluate fresh concrete workability.
Moreover, it is being more sensitive compared to the well known slump test.
It can simply and clearly distinguish between stiff mixes as well as floppy ones.
Very useful numerical limits for the evaluated properties controlling the workability levels of very low, low, medium, high and very high were proposed.
