Compressive strength of geopolymer concrete modified with nano-silica: Experimental and modeling investigations
TL;DR: In this article , a detailed review on the effect of nano-silica (nS) on the compressive strength (CS) of geopolymer concrete composites was provided, and a large amount of mixed design data were extracted from literature studies to create five different models including artificial neural network, M5P-tree, linear regression, nonlinear regression, and multi logistic regression models for forecasting the CS of GPC incorporated nS.

The Role of Calcium Carbonate in Cement Hydration
TL;DR: In this paper, it is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.
