Cement

TL;DR: In this article, the authors determined the autogenous shrinkage of fly ash and blast-furnace slag containing binders using both manual and automated shrinkage measurements and showed that internal curing by means of superabsorbent polymers is successful, independent of this long term higher rate of shrinkage in mixtures with supplementary cementitious materials.

TL;DR: In this paper, the influence of carbonation on the microstructure of cement paste cast with Ordinary Portland Cement, fly ash based Portland Pozzolana Cement (PPC) and Limestone Calcined Clay Cements (LC3) using X-ray diffraction (XRD), thermal analysis (TGA), scanning electron microscope (SEM) and mercury intrusion porosimeter (MIP).

TL;DR: In this paper, the impact resistance and strength performance of concrete mixtures with polypropylene and silica fume is examined and it is shown that using 0.5% polypropane fiber in the silica mixture increases compressive split tensile, and flexural strength, and especially the performance of concretes under impact loading.

TL;DR: In this paper, the degradation mechanisms of natural fiber in the alkaline and mineral-rich environment of cement matrix are investigated by designing a contrast test to embed sisal fibers in pure and metakaolin modified cement matrices.

TL;DR: In this article, the compressive strength of MPC mortar with fly ash contents was measured at ages of 3h, 1d, 7d and 28d using XRD and SEM.
