Cement

TL;DR: In this article, the authors investigated self-compacting concrete (SCC) with levels of up to 80% cement replacement by fly ash in mixes adjusted to give constant fresh concrete properties.

TL;DR: In this paper, the properties of colloidal nano-silica (CS)/waste glass cement composites were investigated and compared with plain mortar, and the results showed that incorporation of WG has a positive effect on the mechanical properties of cement mortars especially when CS is presented.

TL;DR: In this article, an experimental program is presented in order to evaluate the influence of aggregates grading and water/cement ratio in workability and hardened properties of mortars, and some correlations are presented among hardened properties and the compressive strength.

TL;DR: In this paper, the impact of four different hydrated magnesium carbonates (HMCs) as cement replacements of either 20 or 50% accelerated carbonation (20 °C, 70-90% RH, 20% CO2) is compared with natural curing (20°C, 60-70% RH), ambient CO2).

TL;DR: In this paper, the results of the physico-chemical characterization of original mortars and plasters and the evaluation of the repair ones prepared with natural hydraulic lime (NHL) as binding material and siliceous sand and crushed brick as aggregates were presented.
