of the cement stone.Accordingly, a graphical procedure is given for predicting the strength of ordinary concretes for a given water-cement ratio and lean air-entrained concretes for a given "equivalent" water-cement ratio.Compressive strength may also be predicted by means of numerical formulae.doi...
especially the RCS after elevated temperatures exposure, are quite few in number yet. In addition, studies related to predicting the behavior of concrete reinforced with nano additives, particularly its compressive strength, are extremely rare. The positive...
It is well known that the ultimate compressive strength of concrete filled tubular stub-column is higher than that of the simplified evaluating value because of the confinement effect of infilled concrete. In this paper, It is compared the experimental results of other researchers with estimated one...
compressive strength are not available yet. However, the formulation proposed for concrete in the Model Code 90 may be used. This code proposes a peak strain of 0.2% and a compressive fracture energy ofGf=15+0.43fc−0.0036fc2. It should be noted that this formula is only applicable for ...
According to the test results, Abram [20] concluded that the water-cement ratio (w/c) is the most significant factor among all the influencing factors of concrete strength and produced the empirical formula of the two, known as the renowned Abram principle. Despite the fact that Abram did ...
the compressive strength of concrete;the coarse aggregate used for making concrete should have adequate strength.Only the strength of coarse aggregate matching to those of mortar matrix,the better effect could be achieved,otherwise the strength of coarse aggregate and matrix couldn't be fully utilized...
There is a complex high-dimensional nonlinear mapping relationship between the compressive strength of High-Performance Concrete (HPC) and its components, which has great influence on the accurate prediction of compressive strength. In this paper, an efficient robust software calculation strategy combining...
The 28-day compressive strength is even used as the main parameter in the concrete design and can be regarded as an indicator for such materials. Moreover, the simplicity of measuring this property and its observed relationship with other properties at the microstructural level contributes to its ...
