Prediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Proposal Prediction on the Concrete Compressive Strength Using Supervised Learning
The high performance concrete is a highly complex material that consists of cement, water, blast furnace slag, super-plasticizer, coarse and fine aggregate. All of the materials play a certain role in the compressive strength of concrete. Combined with the information about age, the compressive strength of concrete is determined by eight attributes: 1. Cement (kg/m!) 2. Fly ash (kg/m!) 3. Blast...
متن کاملRidge Regression for the Prediction of Compressive Strength of Concrete
In this paper, regression analysis method i.e., traditional method and ridge regression is applied on the dataset collected for the prediction of compressive strength of concrete. When regression analysis is applied and data set is increased or decreased, the regression coefficients have drastically changed their values like the negative coefficients changed to positive or vice versa. So, tradi...
متن کاملNumerical validation of compressive strength prediction for hollow concrete blocks
The results of a numerical modeling program to evaluate the behavior of hollow concrete blocks under uniaxial compression are addressed. It has been considered appropriate to use interface elements to represent the confinement effect at the top and bottom of blocks. The response of the numerical simulations is compared with experimental data of masonry units. Laboratory tests were carried out u...
