The influence of mineral admixtures on the short and long-term performance of concrete
Tahir Gönen,Salih Yazicioglu +1 more
TL;DR: In this paper, a laboratory study on the performance of concrete by adding mineral admixtures, silica fumes (SF) or/and fly ash (FA) was conducted, which showed that adding of both SF and FA slightly increased compressive strength, but contributed more to the improvement of transport properties of concretes.

Evaluation of Chloride Penetration in High Performance Concrete Using Neural Network Algorithm and Micro Pore Structure
TL;DR: In this paper, a numerical technique for chloride diffusion in high performance concrete (HPC) using a neural network algorithm is proposed, where seven material components in various mix designs and duration time are selected as neurons in a back-propagation algorithm, and associated learning of the neural network is carried out.
