TL;DR: Foamed concrete possesses characteristics such as high strength-to-weight ratio and low density as discussed by the authors, which reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the labor cost during construction.

TL;DR: In this paper, the mechanism of autogenous shrinkage of high performance concrete and influential factors in its development are discussed, and the effects of SCMs on autogeneous shrinkage, relationship between different types of shrinkage and auto-shrinkage as well as the effect of internal curing on auto-shrinkage are investigated.

TL;DR: Limestone powder has been widely used in cement-based materials; and reportedly, can influence their properties by filler, nucleation, dilution and chemical effects as mentioned in this paper. But, the action mechanism of LS mainly depends on its particle size and amount.

TL;DR: In this paper, microstructural changes in alkali-activated slag (AAS) mortars after carbonation using XRD, FTIR, DTG, 1 H NMR and SEM examinations were investigated.

TL;DR: In this article, an experimental study was performed to determine the effect of SiO2 nanoparticles on consistency, compaction, hydraulic conductivity, and compressive strength of cement-treated residual soil.
