Nov 24, 2020· However, it was further observed that the strength development of the control PPC and PPC (H 2 O) increased significantly even after 28 days of curing. This was attributed to pozzolanic reaction. Presence of silica (SiO 2) in pozzolana further reacts with the resultant portlandite (CH) from cement hydration to form secondary C-S-H.This promotes additional strength gain in pozzolanic …

Setting on demand for digital concrete – Principles

Jun 01, 2020· Alternative cements include Calcium Sulfo-Aluminate cements (CSA), Calcium Aluminate Cements (CAC), Calcium Sulfate (C$), geopolymers or alkali activated cements and magnesia cements [, , , , ]. Limiting ourselves to binders primarily containing OPC, mixes with CSA, CAC and with different gypsum sources can give a large range of early age kinetics.

Influence of Starkeya novella on Mechanical and

Cement-based materials are subject to degradation during their service life. Most of the structural failures have been associated with corrosion of the rebar due to chloride ingress, alkali aggregate reaction, and/or sulfate attack. Microbial activities, especially in waste water collection points such as sewer lines, may compromise the integrity of concrete structures.

Laboratory Test to Evaluate the Resistance of Cementitious

The reaction of the acid with the cementitious matrix leads to the decalcifiion and the dissolution of calcium-bearing phases–mainly portlandite (CH) and C-A-S-H for Portland cement (PC)-based materials and katoite (C 3 AH 6) for calcium aluminate cement (CAC)-based materials–and the residual anhydrous phases [12,13,14].

Influence of Nano-SiO2 and Nano-TiO2 on Early Hydration of

Calcium sulfoaluminate (CSA) cements were currently receiving a lot of attention because their manufacture produced less CO2 than ordinary Portland cement (OPC). However, it was essential to understand all parameters which might affect the hydration process. This work dealt with the effect of two nanostructured materials, such as nanoSiO2 (NS) and nanoTiO2 (NT), on the properties of CSA …
