Drying shrinkage can be a major cause of deterioration for concrete structures,where the deformation of calcium silicate hydrate (C-S-H) gel is a key issue.
The balance between the silicate, aluminate and sulfate phases in cement is one of the most important aspects during hydration.In particular, a too low supp
Through characterization techniques (XRD, TG / DTA, chemical analysis classical, 27Al and 29Si MAS NMR,Blaine, BET, granulometry laser) and tests of reactiv
The purpose of this work is to investigate compensation function of aluminum sulfate for alite calcium sulfoaluminate cement containing citric acid.X-ray di
Returned concrete is the residual amount of fresh concrete that is not placed at the job site and returns to the ready-mix plant in the truck mixer.Accordin
Alkanolamines have been used to enable early and late strength development of Portland cement and blended cements for more than eight decades.Common alkanol
